COMPOSITION OF REACTIVE POWDER CONCRETE (RPC)

The Constructor

Portland cement – type V 1000 kg/m3 2. Portland cement – type V 955 kg/m 3 2. This compactness gives RPC ultra –high strength and durability.Reactive powder concretes have compressive strength ranging from 200 Mpa to 800Mpa. Typical composition of reactive powder concrete 800 Mpa 1. Fine sand ( 150 – 400 micron) 5001 kg/m3 3.
