ABSTRACT Reactive powder concrete (RPC) is a developing composite material that will allow the concrete industry to optimise material use, generate economical benefits, and build structures that are strong, durable and sensitive to environment.
Silica fume is an ultrafine material with spherical particles less than 1 μm in diameter, the average being about 0.15 μm. This makes it approximately 100 times smaller than the average cement particle. The bulk density of silica fume depends on the degree of densification in the silo and varies from 130 (undensified) to 600 kg/m 3.
