Ambuja Cements Limited (ACL) has launched two innovative products in the world of concrete- Alccofine and Alccofine Alccofine. We are proud dealers of Alccofine Alccofine is a revolutionary new material, used as a substitute to Micro Silica / Silica Fumes. This product is not.

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. Thus, it reduces the penetration of chlorides in concrete and protects embedded steel from corrosion. The presence of extremely fine particles decreases the permeability and improves durability.
International Journal of Structural and Civil Engineering.
Site powered by Weebly. The results are similar even in other two methodologies. Such concretes generally suffer from two major weaknesses i. Packing effect retards ingression of aggressive agents in concrete even by diffusion and thus enhances durability of concrete. Indian Society of Education and Environment No: Development and application of hybrid fiber reinforced concrete.
The impetus for higher and higher concrete strengths also came from demands for exceptional increases in the height of high-rise buildings and for long span bridges. Misconception is widely-held that high strength concretes are, per se, highly durable. Presently, we only cater to the Maharashtra region. ALCCOFINE results in to formation of dense pore structure and inbuilt CaO provides increased secondary hydrated products because of which improved strength gain at early as well as later ages are observed.
Elevated temperatures effects on HSC. Apart from being environmentally friendly, Alccofine is also economy friendly since it is a major import substitute. The following are the salient features of Alccofine Enhances the strength for higher and mid range grades of concrete with optimum utilisation Provides economy in higher grades of concrete Enhances durability of concrete Improves impermeability and eliminates or minimizes thermal cracking Assured quality in terms of even and consistent Particle Size Distribution Environmentally friendly and non-hazardous to health unlike Silica Fumes Immaculate supply chain, delivered around the globe.
The final combination is used as fiber volume fraction – 1. 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 requirement, admixture requirement, strength and durability. Secondary hydrated products formed due to pozzolanic and Cementitious hydration reaction fills the pores. 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.
It is extremely difficult to obtained proper workability, and to retain the workability for sufficiently long period of time with such concrete mixes.
Study on durability of high performance concrete with alccofine and fly ash. Chloride content of the 12003 from each depth were determined and reported. 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. Skip to main content. The processing with other select ingredients results in controlled particle size distribution PSD.
ALCCOFINE is a specially processed product based on slag of high glass content with high reactivity obtained through the process of controlled granulation.
Crushed Basalt rock was used as coarse aggregate and local river sand was used as fine aggregate. Chloride ion penetration is the most frequently specified durability criterion for a long term service life of concrete structures. We are proud distributors of Alccofine The mineral admixture Alccofine enhances strength of concrete, modulus of elasticity along with workability, durability and reduction in segregation.
Such concrete suffer from two major weaknesses. Click alccofin to sign up. 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 123 efficiently. High range water reducers HRWR are extensively used to alccofnie placement with low water contents. This refines the concrete microstructure and enhances the degree of impermeability and the strength characteristics of concrete.
In this methodology, the binder content and admixture content were kept constant and the outcome on water requirement, workability and compressive strength were measured. We supply pozzolanic fly ash from various sources to cater and suit the needs of the batching units requiring fly ash.
Denser pore matrix restricts chloride penetration and alkalinity forms passive layer on steel and protect it from corrosion. Sukerkar Mansion, First Floor, M. Fire response of hybrid fiber reinforced concrete to high temperature. 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.
Help Center Find new research papers in: To estimate effect of mineral admixture Alccofine on durability of Hybrid Fiber Reinforced Concrete.
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 alccotine undesirable, and often even harmful from a durability point of view. Durability aspects of standard concrete.
