引气混凝土的应力-应变曲线试验研究

Experimental study on the stress-strain curve of air-entrained concrete

在对普通混凝土应力-应变曲线研究的基础上,分析评价了引气混凝土峰值应力和峰值应变的关系,提出了引气混凝土的应力-应变曲线方程式,并指出了方程中的参数和含气量的定量关系。

Based on the research of stress-strain curves of ordinary concrete, the relation of peak stress and peak strain and the equations form of stress-strain curves of air-entrained concrete was put forward.The relation of parameters of the equations and air content was gaven.
