| 摘 要： | 当前对混凝土的抗裂性能提出的要求越来越高。本文结合九·五国家科技攻关课题《提高碾压混凝土抗裂能力的研究》 ,主要从水泥矿物成分和掺合料对抗裂性能的影响进行试验研究分析。在保证混凝土的强度基本不变的情况下 ,外掺水泥矿物成分和掺合料能降低混凝土的弹性模量 ,提高混凝土的极限拉伸值 ,从而提高混凝土的抗裂能力

| Abstract: | Today,high crack resistance concrete has been more and more required.We associate this paper with the scientific task:The Research of The Improvement of The Crack Resistance of The Concrete,and study the influence of the mineral compositons and the admixtures on the crack resistance.The result shows that the elastic modulus of the concrete can be decreased and the ultimate extensibility can be increased by adding mineral components and admixtures with little change of strength,and then the crack resistance of the concrete is improved. |
