市政工程中的道路、桥梁、给排水构筑物等多半是混凝士或钢筋混凝土结构,所以混凝土工程施工和混凝土构件生产是工程实践中最常遇到的,大家有很多丰富的经验,但要做到混凝土不发生裂缝,却不是一件容易的事。这是因为混凝土由多种原材料组成,从原材料准备到养护拆模要经过多道加工程序,又要在露天下全年施工,受气候影
Municipal engineering roads, bridges, water supply and drainage structures are mostly concrete or reinforced concrete structures, so the concrete construction and concrete components production is the most commonly encountered in engineering practice, we have a lot of rich experience, but to do It is not easy to get concrete without cracking. This is because concrete consists of a variety of raw materials, from raw material preparation to maintenance demolition to go through multi-channel processing procedures, but also in the open air throughout the year construction, by climate
