Effects of Calcined clay minerals and Silica fume on the compressive strength of concrete

Pozzolanic materials are well known as potential replacements for cement manufacturing in order to increase compressive strength and improve durability of concrete in different environments and leading to save energy particularly reducing global warming effect. The present study reveals the effect o...
