摘要
对夏季高温日晒、风吹的施工环境进行了模拟,考察了采取两种养护措施和掺加三种特殊材料对混凝土在此模拟环境下早期收缩性能的影响。通过复掺聚丙烯纤维和膨胀剂,研制了一种在夏季施工环境下10d内几乎不产生收缩的混凝土,并对在夏季环境下混凝土的养护提出了具体的建议。
The high temperature and wind-blown environment of concrete construction in summer is simulated.In this simulated environment,the effects of two kinds of curing measures and three kinds of special materials on the early shrinkage properties of concrete are studied.Through combined adding polypropylene fibers and expansion agent in concrete,a kind of concrete which is almost non-shrinkage in this simulated environment within 10 days is developed.And specific curing measures of concrete construction in summer are proposed.
