Abstract
An experimental work was performed to study the effect of hybrid fibres on the strength and durability behaviour of waste glass powder (GP) based High performance concrete (HPC). HPC of M60 grade was designed using the IS method with 15% waste glass powder and four different proportions of hybrid fibres are added with concrete ingredients. Hooked end steel fibres and polypropylene fibres were used in hybrid form. The variables considered were (i) Hooked end steel fibres in volume fractions viz. 0.75%, 0.85% and 1% and (ii) polypropylene fibres viz. 0.15% and 0.25%. Addition of fibres in hybrid form enhanced the engineering properties such as the compressive strength, split tensile strength, flexural strength, first crack and failure load under impact. To study the durability, two laboratory tests, water absorption and porosity were carried out for 15% waste glass powder with different proportions of hybrid fibers for different curing periods. The hybrid mix with the combination of 1% steel fibres and 0.25% polypropylene fibres in volume fractions gave better performance based on the strength and durability properties than the other combinations.
