Abstract
Fly ash microsphere (FAM), a high value-added by-product, are powdered hollow beads separated from fly ash in power plants. This paper investigated the effects of FAM as a mineral admixture on the 3 d hydration and microstructure of cement. A composite binder containing inert quartz powder with a surface area similar to that of FAM was selected as the control sample. The results show that FAM has a low reaction degree at room temperature because...
