摘要
高强砼由于水泥用量较大,水灰比很低,当用于较大体积(最小的断面尺寸>1m)构件时,砼内部有较高的温升,早期强度较高,在砼内部温度下降到负温以前,砼已产生足以抵抗冰冻的强度。故可不用防冻剂进行冬季施工。
There will generate higher temperature evolution and higher early strength in high strength concrete because of higher cement content and lower w/c. Before the temperature of concrete center is minus-temperature of strength concrete has been enough to against frost. Therefore, the antifreezing admixture cannot be used in winter construction for high strength concrete in bulk.
