Effects of metakaolin and nano silica on the compressive strength and microstructure of cement mortar
This study examines the effects of metakaolin (MK) and nanosilica (nS) on the setting time, compressive strength, and microstructure of cementitious binders and cement mortar. Portland cement PC40 was partially replaced with MK at levels ranging from 5% to 20% by mass of the binder, while nS was added at concentrations...
