摘　　要：定义了海砂型内掺氯离子与普通型内掺氯离子,研究了二者在混凝土中的结合规律,并探讨了粉煤灰对海砂型内掺氯离子结合的影响。结果显示,海砂型内掺氯离子存在一个固定的结合率(低于普通型内掺氯离子);掺加粉煤灰使海砂型内掺氯离子结合率降低。Sea- sand- inner- introduced - chloride and normal - inner- introduced - chloride are defined in this paper. The difference between the bonding of these two kinds of chloride, and the affect of fly ash on the bonding situation am studied. As the results suggest, them is a constant bonding ratio of sea sand inner introduced chloride which is lower than that of normal chloride. In addition, fly ash makes the bonding ratio of sea - sand - inner - introduced - chloride lower.

关 键 词：内掺氯离子 海砂 氯离子结合率
