Metakaolin and calcined clays as pozzolans for concrete: a review
B.B. Sabir,S. Wild,J. Bai +2 more
TL;DR: The use of metakaolin (MK) as a pozzolanic material for mortar and concrete has received considerable attention in recent years as mentioned in this paper, which is part of the widely spread attention directed towards the utilisation of wastes and industrial by-products in order to minimise Portland cement consumption, the manufacture of which being environmentally damaging.
