自密实超高强混凝土力学性能试验研究

The experimental study on mechanical properties of super high-performance self-compacting concrete

首先对自密实混凝土的定义及优点作了简介,并列举了几篇国内外关于自密实混凝土的基本力学性能、自密实混凝土与振捣混凝土力学性能的比较以及掺入超细粉煤灰和超塑化剂对自密实混凝土性能的改善。随后,作者通过试验的方法对自密实混凝土的基本力学性能做了研究,并比较了圆柱体抗压强度与劈拉强度、圆柱体抗压强度与弹性模量以及三者与混凝土密度之间的关系。

This paper firstly introduces the definition and advantages of self-compacting concrete(SCC). Several native and foreign studies on the basic mechanical properties of SCC, the comparison between SCC and normal concrete and the reform on the properties of SCC with ultrapulverized fly ash and superplasticizer. Subsequently, the author has carried out an experiment to study the basic mechanical properties of SCC. The relationship between cylinder strength and splitting strength, cylinder strength and elastic modulus and the above three mechanical parameters and the density of concrete has also been listed.
