Abstract

Concrete in construction, is a structural material consisting of a hard, chemically inert particulate substance, known as aggregate (usually sand and gravel) that is bonded together by cement and water. Concrete is good in compression but weak in tension, hence new advancements are implemented like using steel fibres (SF) in concrete which will strengthen the tensile zone. An increased compressive, splitting tensile and flexural strength, flexural toughness, surface hardness, and abrasion resistance, and a decreased water absorption and sorptivity of concrete with an increased steel fibre content from 1% to 2% can be observed (Kaplan et al.2021). The rice husk itself has a very rough surface which is abrasive in nature so, it cannot be degraded naturally. This would result in improper disposal problems. Hence the usage of RHA will be a sustainable approach. For the current study, 5%, 10% and 15% of cement will be replaced with RHA and a constant SF of 1.75% as total volume of concrete will be added. The fresh, mechanical and durability parameters of the modified concrete will be studied to know the combined effect of SF and RHA. Moreover, non-destructive tests will also be performed to know the in-depth hardened concrete properties
