Effect of ZnO on the pozzolanic activity and physico-mechanical properties of modified metakaolin cement mortar composites

Abstract Metakaolin (MK) is commonly added to enhance the mechanical and durability properties of concrete. The pozzolanic activity of MK can be improved by calcining approximately ≈ 1 wt% ZnO with kaolin. However, the role of ZnO in enhancing the pozzolanic activity of MK remains unclear. The aim o...
