| 摘 要： | 研究了砂率变化对混凝土塑性收缩裂缝的影响,指出较小砂率和较大砂率混凝土拌合物的塑性收缩裂缝相对较小,而中间某一砂率对应的裂缝相对最大,这一最大裂缝的砂率变化范围大致在36%-43%之间,水分蒸发速率随砂率的增大而减少。

| Abstract: | The effects of sand percentage on plastic shrinkage cracking of concretes placed in laboratory-controlled environment condition were investigated. Point out concretes with lower or higher sand percentage were not more sensitive to plastic shrinkage cracking than concretes with moderate sand percentage which changed in about 36%--43%. Water evaporation rate decreases as the magnitude of sand percentage increases. |

| Keywords: | plastic shrinkage cracking sand percentage evaporation rate |
