We supply both in bulk and bag form. 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.
In fact concrete slump is seen to be improved, due to the dense packing of cementitious material, producing low void content. Part 8-Testing of hardened concrete, depth of penetration of water under pressure.
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. According to this test the cubes were initially water-cured for 28 days, and then exposed to water pressure of 5 bars for 72 hours after which the cube was divided and the depth of water penetration measured.
This reduces the permeability of hydrated products to great extent and protects concrete from chemical attack. 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.
Chloride ion penetration is the most frequently specified durability criterion for a long term service life of concrete structures. The slabs used were water cured for 28 days. Denser pore matrix restricts chloride penetration and alkalinity forms passive layer on steel and protect it from corrosion.
Help Center Find new research papers in: The final combination is used as fiber volume fraction – 1. Misconception is widely-held that high strength concretes are, per se, highly durable.
Addition of Hybrid fibers and mineral admixture Alccofine increases the ductility, crack resistance strength and durability of concrete. Email this article Login required. International Journal of Structural and Civil Engineering.

Alccofine is not only useful in delivering better strength, but is also commercially competitive. Such concrete suffer from two major weaknesses.
Physically the product is unique with regards to its particle size distribution. The processing with other select ingredients results in controlled particle size distribution PSD. Engineers are, by nature, fascinated and indeed obsessed, by high strength and very high strength concrete.
We supply pozzolanic fly ash from various sources to cater and suit the needs of the batching units requiring fly ash. Alcdofine estimate effect of mineral admixture Alccofine on durability of Hybrid Fiber Reinforced Concrete.

Ambuja Alccofine 1203
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.
This refines the concrete microstructure and enhances the degree of impermeability and the strength characteristics of concrete. This paper presents effect of hybrid fibers and alccofine on estimation of durability of hybrid alcdofine reinforced concrete with different combinations. Thus, alccpfine reduces the penetration of chlorides in concrete and protects embedded steel from corrosion. The decrease in water demand is because of high glass content which has water repelling property.
In high performance concrete applications, Silica Fume is generally proposed as the appropriate cement extender where high strength, low permeability are the prime requirements.
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. These materials used were dried completely before using. Development and application of hybrid fiber reinforced concrete.
It is a non-metallic product consisting essentially of glass containing silicates and Alumino Silicates of lime. Indian Society of Education and Environment No: Owing to this high level of fine-ness, the product has very high level of penetration, specially when used for jobs such as grouting for voids or microcracks in concrete or rocks or voids in soil.
ALCCOFINE is a specially processed product based on slag of high glass content with high reactivity obtained through the process of controlled granulation. Durability test measuring the water permeability showed better results than the Silica Fume.

The raw materials are composed primary of low calcium silicates. Site powered by Weebly. Presently, we only cater to the Maharashtra region. It is produced using specialized machinery to attain the desired level of particle size distribution.
This results in denser pore structure and ultimately higher strength gain. At the end of this time powdered samples by rotary impact hammer are obtained at various depths,mm. These trials results shown following benefits:
