摘　　要：采用湿磨处理工艺制备一系列细度的混凝土浆状掺合料,研究浆状掺合料混凝土在人工海水环境中的抗化学侵蚀性能。结果表明,不同方式处理的粉煤灰及原状粉煤灰的掺入,一般均在一定程度上改善其混凝土抗化学侵蚀性能;不同方式处理的矿渣掺合料的加入,均在一定程度上恶化了混凝土的抗化学侵蚀性能;粉煤灰同矿渣的复合能明显改善矿渣混凝土抗化学侵蚀性能差的弱点。A kind of miner admixture slurry with different fineness was manufactured by means of wet-milling with stirring mill.The effect of mineral admixture treated by dry milling and wet milling on chemical corrosion resistance of concrete in artificial seawater was investigated in this paper.Results showed that,the chemical corrosion resistance of concrete with fly ash treated by different grinding mode is improved,and the chemical corrosion resistance of concrete with slag is relatively inferior.The compound of fly ash can improve chemical corrosion resistance of concrete with slag.
