| Abstract |
This study examines the relationship between the flexural and compressive strengths of early strength portland cement (ESPC) mortars
containing limestone powder (LP). Nineteen different mortar mixtures were classified into three groups based on the blaine of the LP. The
addition ratio (��� ) of LP for the partial replacement of ESPC varied from 0% to 30% in 5% increment for each group. Test results
revealed that both the 28-day compressive strength and flexural strength of ESPC mortars decreased with an increase in ��� , with steeper
decreases for mixtures with higher blaine of LP. This pattern was insignificantly affected by the curing condition. Flexural strength of
ESPC mortars could be evaluated as the square root of the 28-day compressive strength. Based on regression analysis of the test data,
empirical equations were proposed to assess the flexural strength gain of ESPC mortars containing LP. |
