Forming progress of hydration productions CH are analyzed in this paper by ways of SEMs of hardened cement paste with or without ground granulated blast furnace slag and high-calcium fly ash. It presents that minerals with latently hydraulic or pozzolanic are apt to absorb CH crystal to grow around it. There are clearly hydraulic reactions in the partial surface of mineral grains connecting with CH crystal and there is little hydration in the part without CH surrounding. It indicates that increasing the absorbability of mineral grain for CH crystal is probably a useful method to advance reactivity of minerals with low activity.

To improve the application of low-quality aggregates in structural concrete, this study investigated the effect of multi-purpose mineral admixtures, such as fly ash and ground granulated blast-furnace slag, on the performance of concrete. Accordingly, the primary performance of low-quality recycled aggregate concrete could be improved by varying the replacement ratio of the recycled aggregate and using appropriate mineral admixtures such as fly ash and ground granulated blast-furnace slag. The results show the potential for the use of low-quality aggregate in structural concrete.
