Abstract
In this study, the strength development of mortar specimens incorporating limestone powder is investigated varying the source, the specific surface area, and the dosage of limestone powder. The experimental results demonstrate that concrete incorporating limestone powder remarkably improves the strength development at low curing temperature. The effect of improving the strength development by limestone powder greatly depends on the specific surface area and the dosage of limestone powder. Finally, it is concluded that the mechanisms of the strength development by limestone powder are mainly based on contributing the surface of limestone powder to the site for forming C-S-H and the filler effects to macro pores in capillary pores.
