Basic Properties of Reactive Powder Concrete

Abstract

The objective of this research was to study the guidelines for the design and development ofreactive powder concrete. The properties studied were physical and mechanical properties of reactivepowder concrete. The physical properties were water reducing ability and setting time. Moreover, themechanical properties tested were compressive strength at the ages of 1, 3, 7 and 28 days. Frompreliminary test results, it was found that the optimal water reducing agent content for producing the ultrahigh strength concrete (UHSC) which caused the highest compressive strength of concrete at the age of28 days was 6% by weight of cement. The suitable content of silica fume was 25% by weight of cement.Furthermore, the optimal water-to-cement ratio (w/c) for producing the reactive powder concrete (RPC)was 0.23.
