| 摘 要： | 采用平板状试件研究了混凝土早期抗裂性与强度的关系。试验结果表明，混凝土强度越高，尤其是早期强度越高，其早期抗裂性越差。早期养护状况对混凝土抗裂性有重要影响。据此，提出了防止早期裂缝产生的相关建议。

| Abstract: | The relationship between the strength and the resistance to cracking of concrete at early age were studied by using plank concrete specimens.The testing results showthat the higher of the concrete strength are,the weaker of the resistance to cracking of concrete at early age are.Curing condition of concrete at early age can remarkably affect the resistance to cracking of concrete.Some suggestions about preventing from cracking of concrete at early age were also proposed. |
