掺矿物掺合料混凝土抗氯离子渗透性龄期研究

Research on the ages of osmosizing performance of mineral admixture anti-chloride

采用ASTM C1202标准测试了分别掺有粉煤灰、矿渣、硅灰的混凝土28 d和91 d的6 h电通量并测试了7 d,28 d,91 d抗压强度,分析了矿物掺合料对6 h电通量的影响规律以及强度增进率和电通量变化率之间的关系,为合理确定矿物掺合料混凝土抗氯离子渗透性能测试龄期提供了依据。

It adopting the standard detection ASTM C1202 detects the 6h dielectric flux of the concert 28 d and 91 d which mix with fly ash, slag, wollastonite and the anti-pressure strength of 7 d, 28 d and 91 d, analyses the affection redes of mineral admixture to 6 h dielectric flux and the relation between the enhancement ratio and the rate of change of dielectric flux, gives the reference to reasonable decide the ages of osmosizing performance of mineral admixture anti-chloride.
