由于外加剂的使用,可以更迅速获得承受荷载所必需的结构强度。于是,人们从冰点下降与方便施工的角度考虑。力图通过掺入相当数量的所谓“高效防冻剂”(如—15℃、-20℃防冻剂等),以期达到消除冻害。取消繁琐的保温设施,实现负温早强等目的。然而。既使掺入水泥重量15%的复合外 Due to the use of admixtures, the structural strength necessary to withstand the load can be obtained more quickly. As a result, people consider the drop from the freezing point and ease of construction. It seeks to eliminate frost damage by incorporating a considerable amount of so-called “high-efficiency antifreeze” (eg, -15°C, -20°C antifreeze, etc.). Remove cumbersome insulation facilities and achieve negative temperature early and other purposes. however. Even compounded with a 15% weight of cement
