SFRC Flooring and Nano Silica Densification : The Cutting Edge Green Technology
SuStainable and Green ConStruCtion
LTFS is a name that has become synonymous with quality
flooring solutions. We bring in state-of-the-art machinery
S 15 R laser screed machine with telescopic boom for
the purpose of laying the floors which has many advantages in
comparison to Conventional VDF. Flooring.
We prefer Steel fibre reinforced concrete as an alternate to
traditional mesh reinforcement. Glued Steel Fibre Reinforced
Concrete (SFRC)-provides you with a time saving and cost
efficient solution for flooring. Being multi-dimensional
reinforcement it offers following advantages:-
– Optimal Load Bearing,
– Optimal Crack Control,
– High Fatigue Resistance,
– High Impact Resistance,
– Easier to Maintain,
– Longer Lifespan,
– Optimized Thickness,
– Timesaving Construction,
– Better Performance,
– The Ductile Steel Fibre Floor With Stands
Moderate Deformations, Minimizes Curling of
Concrete Slab;
– Easier and More Accurate Installation of Super
Flat Floor.
Steel fibres are
commonly used in
concrete to provide
structural (load-
bearing) capacity
and for the control
of shrinkage-induced
cracking. Steel fibres
for reinforcing concrete
are manufactured from
cold-drawn wire and are
used in grade or ground supported floors. Normally the preferred
length is 60 mm, with aspect ratios of 80 (ratio of length to
nominal diameter). In order to gain pull-out resistance, fibres
have hooked end profile.
Use of Steel Fibres in industrial and warehouse flooring
reduces energy consumption by 16% (Approx.) per sq m in
comparison with steel bar / mesh reinforcement. Also, steel fibres
act as environment friendly concrete reinforcement designed
to offer an easy to use alternative for traditional steel mesh and
bar reinforcement. Depending on the finished product type,
different top wire rod sources are applied. On the overall Steel
Fibre Production volume, manufactures can state the percentage
of recycled steel used in their end product which may be around
20%.

Technology from Lythic USA for Densification & Dust-proofing,
creating “The HardWear FloorTM” for existing and newly
trowelled green concrete floors. Until recently, all densifiers used
alkali-metal compounds called “silicates” – such as sodium silicate,
potassium silicate, or lithium silicate. Silicates are old technology.
They have many drawbacks, which are overcome by a new type
of densifier chemistry, colloidal silica Nano Technology.
LYTHIC Colloidal Silica Nano Technology: New Technology for Better Concrete
Reactive Colloidal Silica – nano-sized particles in an acqueous
suspension – are the heart of Lythic advanced concrete treatment
system. Reactive Colloidal Silica is 99.5% pure
silica suspended in an ultra-low surface tension
liquid. The nanometer particles in their low-
viscosity suspension penetrate quickly, deeply, and
cleanly into concrete. Reactive Colloidal Silica also
bonds to itself, a property not found in any silicate
densifier. They react very efficiently with lime in
concrete, making them far more reactive than
conventional silicate densifiers. These reactions
form cementitious compounds in the concrete’s
pores that harden and densify the surface.
– Creates a Hard, Durable Floor
– Low Cost and Easy to Maintain
– “Green” Flooring
Lythic™ Densifier is a blend of inorganic polymer materials
that penetrates slab concrete to increase surface density and
hardness. Utilizing a proprietary and “green” manufacturing
process, Lythic™ Densifier’s unique formulation of uniform,
concentrated, Nano sized particles, suspended in an ultra low
surface tension liquid, penetrates deeply into concrete surfaces
bonding with the cement components of the slab. Lythic™
Densifier makes an extremely hard, dense floor surface that has
increased wear resistance to foot and fork lift traffic. It is water
based and environmentally friendly and is VOC compliant in all
states.
With experience of laying more than 1 Million M2 of floor
in last 4 years, we are here to deliver floors as per International
standards.
Old Technology: Silicate-based Densifiers
New Technology: Lythic Colloidal Silica
Highly caustic with 11 pH or greater
9 pH, a thousand times safer
High viscosity requires scrubbing to break surface tension, adding to labour cost
Low viscosity and simple spray-on application for quick penetration
Slow reacting, can require overnight dwell time
Reacts within minutes. Does not delay project
Alkaline residues require additional labour to remove and treatment as hazardous waste
No alkaline surface residue. No disposal costs
Surface must be rinsed to remove residue as water damage to building and finishes is possible
No rinsing required
Potential for difficult to remove surface whiting
No potential for whiting
Contains water soluble compounds that may be left in the slab and cause problems
Does NOT contribute to alkali-silica- reaction (ASR) which can cause swelling and cracking
Inconsistent and variable sized particles
Consistent 5 nanometer -sized particles
