| 摘 要： | 采用新的实验方法研究了矿渣对水泥浆体早期抗裂性的影响，同时测定了浆体早期抗压强度、抗折强度和收缩率。试验结果表明，在相同水胶比情况下，用矿渣取代水泥，可明显改善混凝上的早期抗裂性，且掺量越高，改善效果越好。通过浆体收缩拉应力的计算分析，证实了掺矿渣浆体的抗裂性高于不掺矿渣浆体．

| Abstract: | The effect of slag on the resistance to cracking of pastes at early age was investigated by a new method, and the compressive strength, flexural strength and shrinkage of the pastes were measured concurrently. The results show that at the same water-binder ratio, the resistance to cracking of paste is significantly improved by addition of slag, and the higher content of slag, the better improving effect. By theoretical calculation and analysis on the shrinkage stress, it is proved that the resistance to cracking of paste with slag is higher than that of paste without slag. |
