【摘要】:研究-3℃和標(biāo)準(zhǔn)養(yǎng)護(hù)條件下,礦物摻合料的摻加對(duì)混凝土抗壓強(qiáng)度、抗氯離子滲透性及孔結(jié)構(gòu)的影響,對(duì)比分析礦物摻合料對(duì)混凝土性能的影響規(guī)律。試驗(yàn)結(jié)果表明:在-3℃條件下養(yǎng)護(hù)時(shí),各個(gè)齡期摻加礦物摻合料的混凝土強(qiáng)度均低于不摻加的,這與標(biāo)養(yǎng)條件下的強(qiáng)度增長規(guī)律不一致;-3℃養(yǎng)護(hù)下礦物摻合料的摻加對(duì)混凝土抗氯離子滲透性能有一定程度的改善,也可以細(xì)化混凝土的孔結(jié)構(gòu),但改善效果沒有在標(biāo)養(yǎng)條件下的顯著。
