近年来对于大型混凝土结构,趋向于大规模连续浇筑并采用早强波特兰水泥,以缩短浇筑周期加快模板周转,从而降低工程费用。但也带来一些不利因素,如水泥水化热问题更加突出,有些结构产生了早期温度裂缝。本文主要讨论早期温度裂缝的成因、影 In recent years, large-scale concrete structures tend to be large-scale continuous pouring and early strength Portland cement to shorten the pouring cycle to speed up the template turnover, thus reducing the project cost. But also brought some unfavorable factors, such as cement hydration heat problem is more prominent, some structures have produced early temperature cracks. This article mainly discusses the causes and effects of early temperature cracks
