如果在掺加超塑化剂的同时减少拌合水量,则C3S水化度下降,而硬化浆体的强度则提高。这主要是由于浆体孔结构改变的缘故,而C-S-H本身变化不大。
When mixing water is reduced , however , C_3S pastes show a lower degree of hydration and a higher compressive strength , This is mainly attributed to the change of pore structure , since only minor alteration of C-S-H nature is found .
