摘要
研究了矿渣掺量(0、30%、50%、70%、100%)对泡沫混凝土试件抗盐侵蚀性能的影响,通过对试件尺寸、质量变化及强度的测试,得到了矿渣的最佳掺量。结果表明:矿渣的掺入可以在一定程度上削弱盐溶液侵蚀带来的试件尺寸、质量和强度的变化;矿渣的最佳掺量为50%,此时试件的平均厚度差最小,质量变化率较低,无侧限抗压强度最高。
The influence of slag content(0,30%,50%,70%,100%)on the salt corrosion resistance of foamed concrete specimens was studied.By testing the size,mass changes,and strength of the specimens,the optimal content of slag is obtained.The results indicate that the addition of slag can to some extent weaken the size,mass and strength changes of specimens by salt solution corrosion.The optimal content of slag is 50%,the average thickness difference of the specimen is the smallest,the mass change rate is low,and the unconfined compressive strength is the highest.
