| Abstract |
High Early Strength cement (HEC) develops strength faster than Ordinary Portland cement (OPC) and is different in mineral composition,
fineness, and chemical composition. This study statistically analyzes the effect of mineral composition, fineness, and chemical composition of
36 HEC samples produced in a single cement plant on the compressive strength of mortar and concrete. The results reflect that Blaine had
the most positive effect on the 1-day compressive strength of both mortar and concrete, but the increase of Blaine showed a negative effect
on the 28-day compressive strength and concrete slump. The contents of C3S showed the most significant effect on the 28-day compressive
strength. Additionally, there was no significant correlation between the 1-day and the 28-day compressive strength of HEC. |
