摘要
在水中冻融循环下,通过基准混凝土和掺加复合防冻剂负温混凝土在冻融循环过程中的试验研究,以抗压强度损失率和混凝土质量损失率作为混凝土冻融耐久性的评价依据,能准确地反映冻融过程中混凝土性能的劣化程度,为西北地区冬季施工提供帮助和理论依据。
With the test condition of freeze-thaw cycles in the water, through the research of benchmark concrete and negative temperature mixed composite antifreeze,it takes the loss rate of compressive strength and quality as evaluations for the freeze-thaw durability of concrete. These reflect accurately the degradation degree of concrete performance in the freeze-thaw cycles, and provide help and theoretical basis for the winter construction in northwest region.
