for Rebar Applications Hilti HIT injection system


1. Post-installed simply works better than

cast-in.

by Jakob Kunz

Post-installed reinforcement works at least as well as cast-in rebars. This has been

proven by the comprehensive testing required for European Technical Approvals

for post-installed reinforcement connections. Consequently, the design process is

straightforward and in accordance with structural concrete codes (ACI 318 & Eurocode

2) for post-installed overlap splices, reinforcement anchorage at simple supports and

connections of columns mainly loaded in compression.

Only straight bars can be post-installed in cured concrete, but cast-in reinforcement

often uses hooks to reduce anchorage length or bends to divert forces. Hilti has thus

invested in extensive research to find solutions that allow post-installed reinforcement

to be used in situations where standard structural concrete detailing would requirehooks or bends. A revolutionary new design method has now been developed on the

basis of this research.

Hilti HIT Rebar Design Method

According to structural concrete building codes, the bond strength of cast-in bars is

limited, even where depth of concrete cover is considerable. Accordingly, in some

zones such as in walls where anchorage depth is often limited, welded transverse

reinforcement or hooks are used to compensate for the reduction in available anchorage

depth. The Hilti Rebar Design Method also makes it possible to reduce anchorage

length while maintaining the high bond strength needed to replace hooks or welded

transverse reinforcement.

Better results through more detailed research

Research has shown that the bond strength of bars anchored with Hilti adhesive

mortars is higher than that of cast-in-place bars, provided there is adequate concrete

cover1. The Hilti HIT Rebar Design Method takes advantage of this increased bond

strength in order to achieve anchorage length reductions of up to 50% compared to

the figures given in building codes.

Frame node connections with straight bars

According to standard reinforcement design concepts, bends are required at moment-

resisting connections. Working together with the Technical University of Munich and

the American University of Beirut, Hilti has carried out theoretical and laboratory

research in order to propose an adequate strut-and-tie model that takes the specific

characteristics of frame node connections with straight bars2 into account.

Connection of members under tension

Where a connection is made between concrete members under predominant tension,

the principles of anchor design should be applied3. As a specialist in anchoring to

concrete, Hilti is well qualified to provide the appropriate solutions. Factors such as the

possibility of concrete cone breakout must be given special consideration.

Post-installed reinforcement for shear loads

Thanks to many years of research, Hilti is also in an excellent position to provide

solutions for post-installed shear interface reinforcement4 for concrete overlays or

post-installed punching shear reinforcement5.

Bond strength depends on concrete cover. Where cover is limited, splitting is the controlling

factor and the red and grey lines therefore show more or less linear functions. Where cover

is sufficient, pull-out begins to become the controlling factor. With Hilti adhesives, the coverlimit is usually higher than that specified for cast-in in concrete building codes (fbd=bond

strength, c=cover, Ø=bar diameter).

2. Basic considerations for fire design

of post-installed reinforcement

Codes

specify minimum concrete cover for protection of the reinforcement against high

temperature depending on the required fire rating.

Since, in case of fire, the behaviour of the bonding material for post-installed bars is

somewhat different to cast-in reinforcement some back ground information is necessary

to provide equivalent behaviour of the post installed system.

Behaviour of steel in high temperatures

Steel changes material properties when its temperature is increased. This is especiallythe case for yield strength as shown by fig.1.

Note: at 560°C steel yield is approx. half of yield strength at room temperature.

Safety approach for fire design

The safety approach for fire design is semi- empirical because it is impossible to

determine a fire statistically. Therefore a standard fire temperature/time curve ISO 834

(fig. 2) has been agreed on for normal cases. In some cases, especially in road tunnels

more stringent temperature/time curves are applied.Note: Safety concept is based on experience, many simplifications on the safe

side have been accepted for design.

ScopeThe sensitivity for high temperatures of the adhesives used for bonded-in bars is

higher than the bond of cast-in bars. A design concept is provided for the design of fire

resistance for bonded-in bars with equivalent safety compared to cast-in bars.

Tests and design concept

Tests to evaluate the relationship between temperature and bond of the adhesives have

been performed. Taking into account the temperature gradients in the concrete for the

various fire ratings a design concept was derived. Testing, high temperature – bond

relation and the design tables are shown in the corresponding reports.

Be aware that steel yield under fire is reduced considerably, and safety factors for fire

design are reduced accordingly as specified in the code.Note that the fire design tables must not be used for cold design (accepted bond

stress under fire may be above the values acceptable for safe cold design).

a.) The maximum load for each individual fire design is performed by the engineer.

The designer determines his individual load depending on the load situation and

individual safety factor combination used.

With this load value he can determine the anchorage length by means of the Hilti fire

design tables.

b) It does not mean that the adhesives withstands the same temperatures as the steel

does, but the tables specify cover and anchorage length that are necessary to withstand

for the same duration the same force as is expected from the steel.

c) It is evident that for simplification the maximum load can be used on the safe side todetermine anchorage length, but maybe steel holds not the same force under fire in the

new building member e.g. with less cover.

Therefore if shorter embedment is requested it is worth to calculate the correct design

load for fire.

That is especially true if higher safety factors or global safety factors for cold design are

used (than there is more reserve in the steel).

Bore hole drilling

Drill Hole to the required embedment depth with a hammer drill set in rotationhammer

mode using an appropriately sized carbide drill bit.

Blow 4 times from the back of the hole (if needed with nozzle extension) with the

hand pump until return air stream is free of noticeable dust.

Valid for:

bore hole diameter d0 20 mm and

bore hole depth h0 20 d (element diameter) or h0 250 mm

Brush 4 times with the specified brush size (brush Ø ≥ bore hole Ø, see Table 7)

by inserting the steel brush Hilti HIT-RB to the back of the hole (if needed with

extension) in a twisting motion and removing it.

The brush must produce natural resistance as it enters the bore hole -- if not the

brush is too small and must be replaced with the proper brush diameter.

Blow again with hand pump 4 times until return air stream is free of noticeable

dust.

Bore hole cleaning

Just before setting an anchor, the bore hole must be free of dust and debris.

For under water application see Table 6 and 7, Annex 11

a) Manual Cleaning (MC)for bore hole diameters d0 20mm and limited bore hole depth h0

Blow 2 times from the back of the hole (if needed with nozzle extension) over the

hole length with oil-free compressed air (min. 6 bar at 6 m³/h) until return airstream is free of noticeable dust.






Blow again with compressed air 2 times until return air stream is free of noticeable

dust.

b) Compressed air cleaning (CAC)

for all bore hole diameters d0 and all bore hole depth h0

c) Cleaning for under water


Injection preparation

Flush 2 times the hole by inserting a water hose (water-line pressure) to the back

of the hole until water runs clear.






Flush again 2 times the hole by inserting a water hose (water-line pressure) tothe back of the hole until water runs clear.

Insert foil pack in foil pack holder. Never use damaged foil packs and/or

damaged or unclean foil pack holders. Attach new mixer prior to dispensing a

new foil pack (snug fit).

Tightly attach Hilti HIT-RE-M mixer to foil pack manifold. Do not modify the mixerin any way.

Make sure the mixing element is in the mixer. Use only the mixer supplied with

the adhesive

Insert foil pack holder with foil pack into HIT-dispenser. Push release trigger,

retract plunger and insert foil pack holder into the appropriate Hilti dispenser.

Discard initial adhesive. The foil pack opens automatically as dispensing is initiated.

Depending on the size of the foil pack an initial amount of adhesive has to be discarded.

Discard quantities are 3 strokes for 330 ml foil pack,

4 strokes for 500 ml foil pack and

65 ml for 1400 ml foil pack.

Inject adhesive

from the back of the borehole without forming air voids

Inject the adhesive starting at the back of the hole, slowly withdrawing the mixerwith each trigger pull.

Fill holes approximately 2/3 full, or as required to ensure that the annular gap

between the anchor and the concrete is completely filled with adhesive along the

embedment length.

After injection is completed, depressurize the dispenser by pressing the release

trigger. This will prevent further adhesive discharge from the mixer.

Overhead installation and installation with embedment depth hef > 250mm

For overhead installation or under water application the injection is only possible

with the aid of extensions and piston plugs. Assemble HIT-RE-M mixer,

extension(s) and appropriately sized piston plug (see Table 7).

Insert piston plug to back of the hole and inject adhesive. During injection the

piston plug will be naturally extruded out of the bore hole by the adhesive pressure.

Under water application fill bore hole completely with mortar.

Bore hole drilling

Drill hole to the required embedment depth with an appropriately sized Hilti

TE-CD or TE-YD hollow drill bit with Hilti vacuum attachment. This drilling

method properly cleans the borehole and removes dust while drilling.

After drilling is complete, proceed to the “injection preparation” step in the

instructions for use.

The Hilti manual pump may be used for blowing out bore holes up to

diameters do ef .

Blow out at least 4 times from the back of the bore hole until return air

stream is free of noticeable dust

Brush 4 times with the specified brush size by inserting the steel brush Hilti

HIT-RB to the back of the hole (if needed with extension) in a twisting

motion and removing it.

The brush must produce natural resistance as it enters the bore hole -- if

not the brush is too small and must be replaced with the proper brush

diameter.

Blow out again with manual pump at least 4 times until return air stream is

free of noticeable dust.

Bore hole cleaning

Just before setting an anchor, the bore hole must be free of dust and debris.

Drill Hole to the required embedment depth with a hammer drill set in

rotation-hammer mode using an appropriately sized carbide drill bit.

Compressed air cleaning (CAC)


Injection preparation

Inject adhesive from the back of the borehole without forming air voids

Drill hole to the required embedment depth with an appropriately sized HiltiBlow 2 times from the back of the hole (if needed with nozzle extension)

over the hole length with oil-free compressed air (min. 6 bar at 6 m³/h) until

the compressor must supply a minimum air flow of 140 m³/hour.

Brush 2 times with the specified brush size by inserting the steel brush Hilti

HIT-RB to the back of the hole (if needed with extension) in a twisting

motion and removing it.

The brush must produce natural resistance as it enters the bore hole -- if

not the brush is too small and must be replaced with the proper brush

diameter.

Blow again with compressed air 2 times until return air stream is free ofnoticeable dust.

Tightly attach new Hilti mixing nozzle HIT-RE-M to foil pack manifold (snug

fit). Do not modify the mixing nozzle. Observe the instruction for use of the

dispenser. Check foil pack holder for proper function. Do not use damaged

foil packs / holders. Swing foil pack holder with foil pack into HIT -

dispenser.

Discard initial adhesive. The foil pack opens automatically as dispensing is

initiated. Depending on the size of the foil pack an initial amount of

adhesive has to be discarded.

Discard quantities are

Inject the adhesive starting at the back of the hole, slowly withdrawing the

to ensure that the annular gap between the anchor and the concrete iscompletely filled with adhesive along the embedment length.

Overhead installation and installation with embedment depth hef > 250mm.

For overhead installation the injection is only possible with the aid of

extensions and piston plugs. Assemble HIT-RE-M mixer, extension(s) andappropriately sized piston plug. Insert piston plug to back of the hole and

inject adhesive. During injection the piston plug will be naturally extruded

out of the bore hole by the adhesive pressure.

After injection is completed, depressurize the dispenser by pressing the

release trigger. This will prevent further adhesive discharge from the mixer.

10. Frequently asked questions

a.) Why is it important not only to specify mortar but the overall application?

Post-installed rebar connections typically have signicant embedment lengths. Theequipment used must therefore allow drilling to be carried out accurately, avoiding crossing

with neighboring holes. If dust remains on the walls of the holes drilled, bond strength as

specied cannot be achieved. The holes must therefore be properly cleaned along their

entire length using a steel brush tted to an electric drill.

Injection without creation of air pockets and bubbles is possible only when it’s done from the

bottom of the hole and when mixer extensions and “piston” plugs are used. Air bubbles may

cause pressure to build up when the rebar is inserted into the adhesive. This pressure can

become so high that the adhesive is squirted out of the hole towards the worker, causing a

hazard. Air can also inhibit proper curing of the adhesive and, last but not least, the presence

of air impedes bonding, reducing the effective bonding length.

b) What does a European Technical Rebar Approval attest to an adhesive?

The product has passed a number of acceptance tests proving that the behavior of post-installed rebar connections is at least comparable to that of cast-in-place rebar connections

(comparable load transfer with a comparable load-displacement behavior) under various

conditions.

c.) Which conditions are assessed for a European Technical Rebar Approval? Bond

strength in different grades of concrete, substandard hole cleaning, wet concrete, sustained

load and temperature inuence, freeze-thaw conditions, different installation directions,

maximum embedment depth, avoidance of air bubbles during injection, durability (corrosion,

chemical attack).

d.) The acceptance tests don’t include re or fatigue loads. Can loads of this kind be

taken up by post-installed reinforcement?

It’s true that the adhesive forms a layer between the concrete and rebar, which may

result in cast-in-place and post-installed rebar connections having signicantly different

characteristics under such conditions. Hilti has performed specic research on these loading

conditions and can provide corresponding design recommendations.

e.) What’s the main difference between cast-in-place and post-installed reinforcement?

While detailing of cast-in-place reinforcement often requires bends or hooks or welded-on

transverse reinforcement, post-installed reinforcement is limited to straight bar ends because

only straight holes can be drilled.

f.) What’s the advantage of the Hilti HIT Rebar Design Method for post-installed

anchorage where depth is limited, e.g. when connecting a slab to a wall?

With cast-in reinforcement, anchorage length can be reduced by using hooks or weldedtransverse reinforcement, which is not possible with post-installed reinforcement. Hilti

adhesives, however, usually provide higher bond strength than that specied in building

codes for cast-in-place reinforcement. Since such applications have a large concrete cover,

the designer can take advantage of the high bond strength of the adhesive by reducing the

anchorage length signicantly.

g.) How can moment-resisting connections be designed for post-installed

reinforcement?

Such connections normally require bends in the connecting reinforcement. The Hilti HIT

Rebar Design Method includes a strut-and-tie model for the design of moment-resisting

connections with post-installed straight bars anchored using Hilti adhesives. Laboratory

tests have proven this model to be correct and it has been assessed by independent experts.

h.) How can concrete members under tension be connected using post-installed

rebars?

Reinforcement in such members is usually hooked back by bending it around the

perpendicular reinforcement in the base member which, again, isn’t possible with post-installed reinforcement. As a highly experienced specialist in the eld of anchoring to

concrete, Hilti is well qualied to provide recommendations on how these principles should

be used to connect such members. It should be noted that due to the possibility of concrete

cone breakout failure, the design of connections of this kind must take brittle failure mode

into account as it is done in Hilti PROFIS Rebar 2.0

i.) Can the post-installation technology also be used for shear reinforcement?

Although this topic is still under research, Hilti already offers well-proven solutions for post-

installed shear interface reinforcement and for post-installed punching shear reinforcement.
