The formation of ettringite has a significant influence on the compressive strength development of CSA-SSC. According to Fig. 14, as the amount of ettringite increases, the compressive strength of CSA-SSC continues to increase. From 3 d to 7 d, the rapid formation of ettringite is accompanied by a large increase in the compressive strength.
