| 摘 要： | 通过试验来探讨外加剂和矿物掺合料共同作用下,不同坍落度对预拌混凝土开裂性能影响的规律和机理;考虑了不同掺量的粉煤灰和减水剂埘预拌混凝土坍落度的影响以及对其力学性能的影响,分析不同坍落度条件下,预拌混凝土的力学性能所反应的抗裂性能的优劣,为更加直观、准确的把握预拌混凝土工程的早期工作性能提供有效的依据.

| Abstract: | The law and mechanism of anti-cracking performance of ready-mixed concrete on different slump by the effects of additives and mineral admixture together are discussed by test.The influence of mechanical properties and slump of ready-mixed concrete under different amount of fly ash and water-reducing admixture is considered.The anti-cracking performance can be judged by the mechanical properties of ready-mixed concrete under the different slump conditions.Hence,an effective gist which can be more intuitive a... |
