Investigation on Properties of Reactive Powder Concrete with Automobile Grinding Steel Waste as Fine Aggregate

Abstract

High strength concrete is seldom used in normal construction practice due to its high cost and difficulties in achieving the desired design strength. This paper gives an insight on using waste material which has been disposed in lands as a sustainable construction material to replace sand and to achieve desired strength. The compressive strength of Reactive powder concrete (RPC) produced in this work was 88 MPa and the flexural strength was 20 MPa. Also the influence of different curing methods on the properties of RPC has been investigated. Durability studies also show that the material satisfies the durable parameters to be used as a construction material.
