DURABILITY OF HYBRID FIBRE REINFORCED CONCRETE

In Hybrid fiber reinforced concrete, hybrid fibers (steel fibers and polypropylene fibers) along with admixture like Alccofine-1203 will be used. The hybrid fiber will help to reduce the cracks due to shrinkage, creep and early age cracking along with an increase in ductility, toughness and fatigue resistance. The mineral admixture (Alccofine-1203) will help to increase the strength of concrete, modulus of elasticity along with workability, durability, and reduction in segregation. Both the mineral admixture (Alccofine) and hybrid fibers (Steel fiber and polypropylene fiber) will be beneficial to HFRC to achieve better structural performance. They also reduce the permeability of concrete and thus reduce bleeding of water. Experiments will be conducted to study the effect of steel fiber and polypropylene fiber in different proportion in hardened concrete. we are conducting Tests like Compressive strength test, Flexural strength test and durability tests like Water permeability test, Acid attack test, Water absorption test and Fire resistance will be conducted on hybrid fiber reinforced concrete using Steel Fiber, Polypropylene fiber, and Alccofine-1203.
