Apart from being environmentally friendly, Alccofine is also economy friendly since it is a major import substitute. Alccofine Site powered by Weebly. Elevated temperatures effects on Novaka J, Kohoutkova A. Packing effect retards ingression of aggressive agents in concrete even by diffusion and thus enhances durability of concrete.
Remember me on this computer. Email this article Login required. 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.
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.
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.
The study presents behavior of hybrid fiber steel fibers and polypropylene fibers reinforced concrete including mineral admixture like Alccofine Crushed Basalt rock was used as coarse aggregate and local river sand was used as fine aggregate.
Sukerkar Mansion, First Floor, M. 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. 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.
Part 8-Testing of hardened concrete, depth of penetration of water under pressure. It is extremely difficult to obtained proper workability, and to retain the workability for sufficiently long period of time with such concrete mixes.
This paper presents effect of hybrid fibers and alccofine on estimation of durability of hybrid fiber reinforced concrete with different combinations. The final combination is used as fiber volume fraction — 1. Strength development increases drastically at early ages and the later on strengths are higher compared to traditional supplementary cementitious material due to its unique Alccifine.
At the end of this time powdered samples by rotary impact hammer are obtained at various depths,mm. Fire response of hybrid fiber reinforced concrete to high temperature. 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.
The slabs used were water cured for 28 days. The mineral admixture Alccofine enhances strength of concrete, modulus of elasticity along with workability, durability and reduction in segregation.
Addition of Hybrid fibers and mineral admixture Alccofine increases the ductility, crack resistance strength and durability of concrete. Alccofine Tech Info Muhammed Muktar — Alccofine is a microfine material comprising of particles much smaller than that of regular Ordinary Portland Cement.
This reduces the permeability of hydrated products to great extent and protects concrete from chemical attack.
