摘要
试验结果表明 :粉煤灰掺量为 2 0 %的混凝土在适量引气的条件下具有良好的抗盐冻性能 ;粉煤灰掺量为 5 5 %的混凝土在掺加UEA膨胀剂后其抗盐冻性能有明显改善 ;
The result of experiment shows that under the conditions of proper air-entraining,concrete with 20% fly ash has excellent frost-resistance The Frost-resistance of concrete with 55% fly-ash which is admixed with united expansive agent(UEA) has been improved greatly The Frost-resistance of sulfate aluminate cement concrete with high volume of fly-ash is dramatically lower than that of silicate cement concrete with the same volume of fly-ash
