Reactive Powder Concrete with Composite Fibres

Abstract

Reactive Powder Concrete (RPC) is a composite material characterised with high strength and durability. Reactive powder concrete is a type of concrete which is made without coarse aggregate, contains cement, river sand, micro silica, super plasticizer and composite fibres with low water cement ratio. RPC can attain high strength characteristics with the addition of fibres. In this project we cast Reactive Powder Concrete specimens of suitable mix proportions by trial and error method and tested its compressive strength, tensile strength and flexural strength characteristics. In order to increase the strength of RPC we have adopted hot water curing at 90°C for 24 hours. Hence, rapid hydration of cementitious materials increases the strength of RPC.
