ALCCOFINE 1206
ALCCOFINE 1206 performs in superior manner than all other mineral admixtures used in concrete
within India. Due to its inbuilt CaO content, ALCCOFINE 1206 triggers two way reactions duringhydration
Primary reaction of cement hydration.
Pozzolanic reaction: ALCCOFINE also consumes by product calcium hydroxide from the
hydration of cement to form additional C-S-H gel, similar to pozzolans.
This results in denser pore structure and ultimately higher strength gain.
INTRODUCTION
As a result of growth in advance technology in concrete, high performance concrete (HPC) has gained
world wide popularity in the construction industry since 1990. In practice, high performance concrete,are generally characterized by high cement factors and very low W/C ratios. Such concrete suffer from
two major weaknesses. It is extremely difficult to obtained proper workability, and to retain the
workability for sufficiently long period of time with such concrete mixes. High dosage of high range
water reducing agents(HRWR) then become a necessity, and resulting cohesive and thixotropic, sticky
mixes are equally difficult to place and compact fully and efficiently. These problem indicate that
there is probably a critical limit for the water content below which high HRWR dosage become not
only essential but also unhelpful and undesirable, and often even harmfull from a durability point of
view.
ALCCOFINE 1206 is a specially processed product based on slag of high glass content with high
reactivity obtained through the process of controlled granulation. The raw materials are composed
primary of low calcium silicates. The processing with other select ingredients results in controlled
particle size distribution (PSD). The computed blain value based on PSD is around 8000cm2/gm and is
truly fine. Due to its unique chemistry and fine particle size, ALCCOFINE 1206 provides reduced water
demand for a given workability, even up to 70% replacement level as per requirement of concrete
performance. ALCCOFINE 1206 can also be used as a high range water reducer to improve
compressive strength or as a super workability aid to improve flow.

PHYSICAL AND CHEMICAL PROPERTIES
ALCCOFINE 1206 also possesses reactive silicon dioxide (SiO2) in amount sufficient to providesignificant pozzolanic activity and benefits, in addition to the hydraulic properties of the cement. This
is largely associated with lowering the calcium hydroxide [Ca(OH)2] content of the concrete by
converting it into more CSH binder and lowering permeability. In hardened concrete, Ca(OH) 2 is
weaker than CSH, additionally SiO2 in ALCCOFINE 1206 reacts with the Ca(OH)2 to produce more CSH
binder. This means that correctly proportioned mixtures made with ALCCOFINE 1206 and Portland
cement can exhibit higher strength, greatly reduced permeability, and potentially greater durability in
many environments when compared to plain Portland cement concrete.

FINENESS, WATER DEMEND AND COLOR
ALCCOFINE 1206, although finer than Portland cement, does not typically have a higher water demand
compared to Portland cement in concrete. This is believed to be true due to its low absorption and
denser packing features (smaller particles of ALCCOFINE 1206 nestling between the Portland cement
grains).
Unlike gray Portland cements, ALCCOFINE 1206 is typically an off-white color. This is attributed to a
combination of inherent chemical and physical properties of blast furnace slag granules. Generally,
higher dosage rates of ALCCOFINE 1206 in a mix design will yield a lighter, brighter concrete color.
CONCRETE AND ALCCOFINE 1206
CONCRETE: PROPORTIONING
ALCCOFINE 1206 concrete may be proportioned by the same methods as Portland cement concretes.
When developing and/or selecting a concrete mixture, make certain that it meets the jobrequirements and applicable documents.
CONCRETE: MAKING AND HANDLING
Concrete made with ALCCOFINE 1206 protects the concrete from premature drying during all stages
of finishing and curing. As with all exterior concretes, proper curing and sealing are essential to obtain
maximum durability.

Generally the higher the ALCCOFINE 1206 dosage, the slower the set time. This provides some
advantages during hot weather concreting. Retarding admixtures and cold weather tend to slow set
times of ALCCOFINE 1206 concrete.
CONCRETE: COLOR
Sometimes, concrete made with combinations of ALCCOFINE 1206 and Portland cement may turn
green of blue-green in color, particularly if proper water curing has been applied. This is usually
attributed to either higher ALCCOFINE 1206 dosages, or to the use of a more finely ground GGBS
product. Once exposed to air for a few days, the concrete surface will usually become light gray or
nearly white with most Portland cements.

SHIPPLING AND STORAGE
ALCCOFINE 1206 is shipped, handled and stored similar to Portland cement. As with all cementitious
materials, ALCCOFINE 1206 should be stored in a clean, dry place. ALCCOFINE 1206 is typically shippedBags.
SUMMARY
The advantages of ALCCOFINE 1206 are observed in the concrete mix design, the initial rate of
strength development was found to be more as compared to other cementations material.
The use of ALCCOFINE 1206 can be effective in enhancing the properties of concrete, both in its fresh
and hardened state. Due to the lower water demand, ALCCOFINE 1206 can be ideally used to:
Lower the water/binder ratio
Use of more cost-effective admixture dosages
A combination of above
ALCCOFINE 1206 is a new generation supplementary cementitious material (SCM) with a built-in high
tech content. In spite of its high fineness it does not increase water demand at the dosage range of 5
to 15 percent of normal OPC in general. In fact concrete slump is seen to be improved, due to the
dense packing of cementitious material, producing low void content. The use of ALCCOFINE 1206
results in hydrated cement matrix to comprise of very small pores.
Strength development increases drastically at early ages and the later on strengths are higher
compared to traditional supplementary cementitious material due to its unique PSD. Judicious use ofALCCOFINE 1206 can produce concrete of superior properties and performance in every way
