摘    要:目前冬期施工中,巳有相关数量的大流动度的负温防冻剂混凝土替代了原有的低塑性防冻剂混凝土。但防冻泵送剂尚无明确的检验标准。为此选取两种防冻剂进行试验,结果表明无论是高效减水剂还是增加用水量改善混凝土的工作性,混凝土硬化初期的性能均受到明显影响。

关 键 词:混凝土  冬期施工  防冻剂  强度  减水剂

Abstract:In nowadays winter construction, traditionally high slump antifreezing concrete has increasingly been replaced by more workable one with low slump. However, there is currently no test standard for pumping antifreeze compound. Experiment on two selected compound shows whether with high efficient water-reducing agent or by adding water volume to improve concrete workability,concrete performance during early hardening period is considerably affected.
Keywords:concrete  winter construction  workability  antifreeze compound  strength
