Effect of Mineral Admixture (Alccofine-1203) on Durability of Hybrid Fiber Reinforced Concrete

Objective: To estimate effect of mineral admixture (Alccofine-1203) on durability of Hybrid Fiber Reinforced Concrete. Methods/Analysis: This paper presents effect of hybrid fibers and alccofine-1203 on estimation of durability of hybrid fiber reinforced concrete with different combinations. The final combination is used as fiber volume fraction - 1.5% (80% steel fibers and 20% polypropylene fibers) by volume of concrete and Alcoffine-1203 with 7.5% by weight of cement. Findings: The study presents behavior of hybrid fiber (steel fibers and polypropylene fibers) reinforced concrete including mineral admixture like Alccofine-1203. The hybrid fibers help to reduce the cracks due to shrinkage, creep and early age thermal cracking along with increase in ductility, toughness and fatigue resistance. The mineral admixture (Alccofine-1203) enhances strength of concrete, modulus of elasticity along with workability, durability and reduction in segregation. Novelty/Improvement: Addition of Hybrid fibers and mineral admixture (Alccofine-1203) increases the ductility, crack resistance strength and durability of concrete.
