摘要：研究了预养时间对掺与不掺防冻剂的C30、C40、C50、C60强度等级负温混凝土抗压强度的影响规律，得出了混凝土的受冻临界强度和相应预养时间。试验结果表明，受冻临界强度随混凝土强度等级的提高而提高；无论是掺加无机防冻剂还是有机防冻剂，均可以降低混凝土受冻临界强度、缩短混凝土达到受冻临界强度所需的预养时间，对C30、C40混凝土的作用效果尤为明显。 Abstract: In this paper, the influence law of pre-curing time on the compressive strength of subzero-temperature concrete whose strength grades are C30, C40, C50 and C60 with or without antifreeze was studied. The critical freezing strengths of concrete and the corresponding pre-curing time were obtained. The test results show that the critical freezing strength increases with the increase of concrete strength grades. Whether it is added with inorganic antifreeze or organic antifreeze, it can reduce the critical freezing strengths of concrete and shorten the pre-curing time of concrete that reaches the critical freezing strength, the effect of pre-curing time on C30 and C40 concrete is particularly obvious.
