摘要
测得了掺有一定数量Ｆ矿粉或粉煤灰高强素混凝土试件的应力应变全曲线，与普通强度混凝土（Ｃ３０）和高强混凝土（Ｃ６０）的应力应变性能作了比较．证明掺有少量Ｆ矿粉或粉煤灰（约为水泥用量１／９）高强混凝土应力应变全曲线与普通高强混凝土应力应变全曲线相同．同时给出了高强混凝土应力应变全曲线方程，试验曲线与理论方程吻合较好．
The high-strength concrete colomns were tested under uniaxial compression on MTS and the complete stress-strain behavior of general high-strentgth condrete and high -strength concrete ohed with dineral powder Of ash were compared. The theoretical equa non of stress-strain curves of concretewere obtained. The difference of failure mechanism between high-strength and low-strength concrete were analysed. The stress-strain curve of high-strength concrete were selected and theorectical curves from calculation are in good agreement with the experimental curves.
