초록

This study aims to evaluate the compressive strength of mortar and the carbon performance index of limestone composite cement to offer a couple of ways to reduce carbon emission in the cement industry. For this purpose, limestone cement made from two types of limestone powders with different fineness was tested under the same W/B and mortar flow conditions. As a result, under the same W/B condition, the mortar flow increased as the replacing rate of limestone increased, but the compressive strength decreased at all ages. On the other hand, under the same flow conditions, the compressive strength during days 1 to 3 decreased with the increase in limestone replacing rate; it was confirmed that the compressive strength of the mortar incorporating limestone for 28 days exhibited an almost same strength level with that of OPC mortar. To evaluate the carbon performance index of limestone cement more accurately, it is suggested that compressive strength and carbon performance should be considered at realistic conditions considering workability such as flow and slump, rather than at the same W/B and constant binder amount conditions.
