Ambuja Cement introduces Alccofine 1203 and 1101 for concrete industry

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. We are proud distributors of Alccofine Owing to this laccofine level of fine-ness, the product has very high level of penetration, specially alccotine used for jobs such as grouting for voids or microcracks in concrete or rocks or voids in soil.
Title of ASTM C ASTM C says that this test method is applicable to types of concrete where correlations have been established between this test procedure and long term chloride penetration by ponding method. Packing effect retards ingression of aggressive agents in concrete even by diffusion and thus enhances durability apccofine concrete.
Ambuja Alccofine 1203
Thus, it reduces the penetration of chlorides in concrete and protects embedded steel from corrosion. Chloride ion penetration is the most frequently specified durability criterion for a long term service life of concrete structures. Engineers are, by nature, fascinated and indeed obsessed, by high strength and very high strength concrete.
Secondary hydrated products formed due to pozzolanic 2103 Cementitious hydration reaction fills the pores. 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.
Ambuja Cement introduces Alccofine and for concrete industry
It is extremely difficult to obtained proper workability, and to retain the workability for sufficiently long period of time with such concrete mixes. In 103 methodology, the binder content and admixture content were kept constant and the outcome on water requirement, workability and compressive strength were measured.
Such concretes generally suffer from two major weaknesses i.

Alccofine when used along with recommended admixtures, have penetration characteristics comparable to chemical grouts such as Silicates and Acryl amides, without the toxicity associated with these chemical grouts. 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.
High range water reducers HRWR are extensively used to ensure placement with low water contents. The average particle size of Alccofine is 4 to a,ccofine microns; the top size d90 alccofie only 10 microns. Novaka J, Kohoutkova A.
Chloride content of the sample from each depth were determined and alccofije. Alccofine is not only useful in delivering better strength, but is also commercially competitive. Misconception is widely-held that high strength concretes are, per se, highly durable.

This booklet presents results of examination carried out on ALCCOFINE in comparison with Silica Fume in concrete, and the effect it has on workability, water a,ccofine, admixture requirement, strength and durability.
Durability test measuring the water permeability showed better results than the Silica Fume. The study presents behavior of hybrid fiber steel fibers and polypropylene fibers reinforced concrete including mineral admixture like Alccofine Due to its unique particle size distribution and inbuilt CaOALCCOFINE results in to formation of dense pore structure, which results in improved workability, workability retention and compressive strength at all ages.
Indian Society of Education and Environment No: 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 harmful from a durability point of view. Apart from being environmentally friendly, Alccofine is also economy friendly since it is a major import substitute.
Such concrete suffer from two major weaknesses. We supply both in bulk and bag form.
