低ca/si比的c-s-h凝胶产物在抑制aar中的作用
DOI: 10.3969/j.issn.1671-7627.2004.04.024, PP. 98-102
Keywords: 碱,ca/si比,c-s-h凝胶,碱-集料反应
Abstract:
碱是混凝土发生碱-集料(aar)反应的重要因素之一.许多资料报道低ca/si比的c-s-h凝胶对碱有强烈的吸附作用.从c-s-h凝胶的组成出发,指出低ca/si比的c-s-h凝胶在抑制aar中的作用,解释了低ca/si的c-s-h凝胶对碱的吸附能力强的原因及其影响因素.为在实际工程应用中掺加混合材来抑制aar反应,提高混凝土耐久性有重大指导意义.
