摘　　要：研究了粉煤灰掺量、细度和水胶比对粉煤灰混凝土抗氯离子渗透性能的影响。结果表明:掺入粉煤灰,可显著改善混凝土早期抗氯离子渗透性能,其抗氯离子渗透性能随水胶比的减小而提高。This paper have studied influence on chloride ions penetration resistence of fly ash concrete from fly ash content, fineness, ratio of water and glue. The results show that mingled fly ash may improve notably Properties of chloride ions penetration resistance in early concrete. This properties increase with ratio reducing of water and glue.
