浅谈施工中高性能混凝土的应用.pdf

题 目：浅谈施工中高性能混凝土的应用及出现 异常凝结的原因 浅谈施工中高性能混凝土的应用及出现异常凝结的原因 内容摘要 高性能混凝土是常规混凝土发展的必然趋势，它不仅满足了建设工程向更高、 更强、更耐久、更多元化的发展需要，而且满足了人类的可持续发展的需要。它 能更多地节约水泥熟料，更多地掺加以工业废渣为主的细掺合料，减少环境污染， 更多地发挥高性能的优势，来降低水泥及混凝土的用量。本文从高性能混凝土的 定义、性能及应用出发，重点介绍了其在施工过程中的质量控制的要求，简要阐 述高性能混凝土在施工中出现异常凝结的现象，并对产生的原因进行了分析。 关键词：高性能混凝土；外加剂；矿物掺合料；配合比；异常凝结 I 浅谈施工中高性能混凝土的应用及出现异常凝结的原因 目 录 内容摘要·······················································································································I 引 言························································································································1 1 高性能混凝土的定义、性能及应用·····························································2 1.1 高性能混凝土的定义 ·····················································································2 1.2 高性能混凝土的性能 ·····················································································2 1.2.1 高性能混凝土的高强性 ·······································································2 1.2.2 高性能混凝土的高工作性 ···································································3 1.2.3 高性能混凝土的高耐久性 ···································································3 1.2.4 高性能混凝土的高体积稳定性····························································3 1.2.5 高性能混凝土的特殊功能 ···································································3 1.2.6 高性能混凝土的经济合理性 ·······························································4 1.3 高性能混凝土的应用 ·····················································································4 2 高性能混凝土的配制····················
