What is it about?
Because of the high contents of cement and silica fume (SF) usually used in those types of concrete, the cost and environmental impact of RPC is considerably higher than conventional concrete.

Why is it important?
The use of supplementary cementitious materials is essential in the conception of new high-tech concrete with particularly tailored properties. Metakaolin allows RPC to achieve early high strength and lower silica fume content.
