摘 要: | 低温早强耐久高性能混凝土,是专门为青藏铁路而进行研制的,就是掺用DZ外加剂,搅拌出的混凝土强度确保混凝土灌注24小时内防止被冻。采用严密的保温措施和先进的施工技术,保证冬季混凝土的施工质量。实践表明:对解决低温条件对混凝土的冰冻损害和解决高原地区混凝土的防腐蚀是一种行之有效的方法。

Abstract: | The low temperature of durable high performance concrete,specifically developed for the Qinghai-Tibet Railway,an additive is mixed with DZ,mixing the concrete strength to ensure that the pouring of concrete to prevent a freeze within 24 hours.Insulation measures and the use of strict construction of advanced technology to ensure the construction quality of concrete in the winter,practice shows that:on the low temperature conditions to the concrete damage and the settlement of frozen plateau corrosion of concrete is an effective way. |
