本文主要讨论了再生粗骨料在普通混凝土配合比设计的基础上进行预吸水。并通过掺加粉煤灰、粒化高炉矿渣粉和缓凝高效减水剂的方法成功配制出同时满足工作性和强度要求的再生混凝土。再生骨料的有效利用替代了天然骨料,即资源化利用,具有重大战略意义,不仅有利于推进绿色、低碳、循环经济发展。还有利于建设生态文明、建设资源节约型、环境友好型社会发展,在转变经济发展方式中培育新的经济增长点。
This paper mainly discusses the pre-absorption of recycled coarse aggregate based on the mix design of ordinary concrete. And by adding fly ash, granulated blast furnace slag powder and retarding superplasticizer successfully prepared at the same time meet the requirements of workability and strength of recycled concrete. The effective utilization of recycled aggregate instead of natural aggregates, that is, the use of resources, with great strategic significance, not only conducive to promoting green, low-carbon, recycling economy. It is also conducive to building an ecological civilization, building a resource-saving and environment-friendly society and fostering new economic growth points in transforming the mode of economic development.
