摘要：
A comparative analysis was made of the individual and combined effects of the constituents of ground hydrated mortar (GHM) on the properties of fresh and hardened alkali-activated slag cement (AASC) pastes, which took into consideration properties such as the liquid/solid ratio, setting time, water absorption, density and compressive strength development. From the results obtained, it is evident that GHM is a multifunctional mineral additive that consists of a 'nucleator seed' and a 'physically active additive'. Moreover, these components function both jointly and separately to micro-reinforce and fill the AASC paste, thereby accelerating its curing and providing a prolonged strengthening effect.
