混凝土是人类最大的建筑结构材料。从我国目前的生产力发展水平、混凝土配制技术、施工性能、设计和使用要求及操作水平来看,目前正处于高强混凝土的配制和使用阶段,这一时期还将经历很长一段时间。文章结合太平湖大桥工程实例阐述了高强铁钢砂混凝土的配合比设计,说明了主要原材料及其性能要求,提出了配制技术和配合比试验。 Concrete is the largest building material of mankind. From the current level of productivity development in our country, concrete preparation technology, construction performance, design and application requirements and operation level, it is currently in the stage of preparation and use of high strength concrete, which will take a long time. Combined with the engineering example of Taiping Lake Bridge, the article describes the mix design of high strength steel grit concrete, explains the main raw materials and their performance requirements, and puts forward the preparation technology and the mix proportion test.
