引气橡胶混凝土的力学性能研究

Mechanical strength of air-entrained rubcrete

以引气橡胶混凝土为研究对象,对引气橡胶混凝土在不同引气剂掺量下的含气量、坍落度进行测定,同时对引气橡胶混凝土的抗压强度、抗折强度、弹性模量进行力学试验,表明引气剂在一定范围内对混凝土的工作性、力学性能有利。在掺量小于0.03%时,对抗压强度、抗折强度有一定程度的提高;作为新型建筑材料,必定具有良好的发展前景。

The air-entrained rubcrete is studied and mensurated about the air content and slump when the air-entraining agent was plunged in different quantity.Meanwhile, its mechanical strength values, such as compressive strength, flexural strength, elastic modulus are tested.The exper- iments show that air-entraining is benefit to improve workability and mechanical property of air-entrained rubcrete within a suitable range of air content.Air-entraining can increase strength in some extent when air content is less than 0.03 percent.As a new architectural material the air-en- trained rubcrete should have a bright future.
