| 摘 要： | 不同的胶凝材料组成对混凝土早期抗裂性能有着不同的影响,文中选择普硅水泥混凝土、微膨胀混凝土、大掺量粉煤灰混凝土和掺硅灰混凝土4种有代表性的混凝土,通过温度-应力试验,对这几种混凝土的早期抗裂性能进行了对比分析,验证了适当的掺合料对提高混凝土早期抗裂性能的有效性。

| Abstract: | Different cementitious material admixtures have different influence on concrete cracking resistance at early age.Four kinds of representative concrete,which are ordinary Portland cement concrete,expansive concrete,a large amount of fly ash concrete and doped silica fume concrete,were chosed to be tested in temperature-stress testing.With the result,the cracking performance of different varieties of concrete at early age were also compared and analyzed.Meanwhile,the efficience of appropriate admixtures to co... |
