Influence of curing temperature on flexural performance of engineered cementitious composites

In order to investigate the effects of different curing temperatures on the flexural performance of engineered cementitious composites (ECC), the four-point bending test is employed in this paper. Four curing temperatures are applied to the ECC specimens, which are 20°C, 40°C, 60°C and 80°C, respectively. The experimental result indicates that the deflection of ECCs at early age decreases gradually as the curing temperature increases. However, the deflection and toughness index of ECCs have no significant change as the curing temperature is above 40°C at later age.
