| 摘 要： | 分析了地下室顶板混凝土开裂的原因。混凝土减水剂的过量使用和用水量过多导致混凝土产生塑性沉降开裂 ;混凝土养护不充分导致膨胀剂UEA未能起到补偿收缩的作用 ;混凝土搅拌、浇注温度过高致使混凝土在冷缩和干缩的共同作用下产生开裂

| 关 键 词： | 混凝土开裂 膨胀剂UEA 混凝土收缩 |

| Abstract: | Analyzed the reasons forming cracks of basement concrete boards.Excess of water reducing agent and water resulted in concrete cracks because of settlement shrinkage.Poor concrete cure lead to UEA not play the role of concrete shrinkage compensation,and higher concrete temperature during concrete stirred and poured lead to concrete shrink with temperature decrease.The combined effect of dry shrinkage and temperature shrink brought on concrete crack. \ |
