关于页岩陶粒混凝土破坏性质的研究

Study on Failure Properties of Shale Ceramsite Concrete

根据页岩陶粒形状的不同,分别使用圆球型、普通型和碎石型这3种不同形状的页岩陶粒进行了混凝土抗压强度试验,最终测定圆球型页岩陶粒制备的混凝土试块抗压强度值为最大,从而得出页岩陶粒的形状是限制混凝土强度等级的主要因素的结论,该结论有利于今后制备更高强度的轻集料混凝土。

According to the different shapes of shale ceramsite, the shale ceramsite with three different shapes, i.e.spherical, common and gravel types are used for testing the compressive strength of concrete, and finally the concrete prepared by the shale ceramsite is tested to have the highest compressive strength, which leads to the conclusion that the shape of the shale ceramsite is the main factor limiting the concrete strength grade. This conclusion is conducive to the preparation of higher strength lightweight aggregate concrete in the future.
