Moreover, taking the C0 specimen as a benchmark, adding LS or CS alone to replace cement, the non-evaporated water content of hydration all showed a decreasing trend, if double-mixed with LS and CS, the non-evaporated water content increased and then decreased with the mass ratio of LS/CS (0.5, 1.0, 2.0), and the optimum mass ratio of LS/CS was about 0.5.
