碱激发废渣配制绿色高性能混凝土

传统水泥生产时,原生资源消耗大,废气、粉尘排放量大,对环境造成严重的污染。为降低水泥生产时的环境负荷,节约生产混凝土的资源与能源,满足混凝土可持续发展的要求,生产绿色混凝土势在必行。本研究利用矿渣、粉煤灰、锂渣、硅灰等工业副产品配制出28天抗压强度达87.5MPa的高强绿色混凝土。

Using Alkali-activated Waste Slag to Produce High Performance Green Concrete

In traditional cement industry,large raw resource consumption and huge waste gas and powder discharge have brought serious pollution to environment. In order to decrease the environmental load and save the energy and resource,meet the requirement of sustainable development,it is urgent for the green concrete. This study used such by-products as slag,fly-ash,lithium slag and silica fume to produce high strength green concrete with 28d compressive strength as high as 87.5MPa.
