Jan 01, 2018· However, GGBS and SF distinctly improve the mechanical properties of ECC with fly ash. For instance, the compressive strength, flexural strength, and first cracking load of ECC (30% FA+ 40% SL) are higher than those of ECC (50% FA). Remarkably, the abovementioned mechanical properties of ECC (65% FA+ 5% SF) are similar to those of ECC (70% FA).
