用途广泛的二废资源──硅粉硅粉是从烟气净化装置中回收的一种灰白色粉尘，其主要化学成份为二氧化硅，属“三废”产品。目前，国内高强度混凝土、硅粉砂浆、硅粉喷射混凝土、复合增强密实剂、低水泥浇注料等科研成果已通过部、省、市级技术鉴定，并在众多工程中应用。在... The most widely used secondary waste resource—silica fume silica fume is an off-white dust recovered from the flue gas purification device. Its main chemical composition is silicon dioxide and belongs to “three wastes” products. At present, domestic scientific research achievements such as high-strength concrete, silica fume mortar, silicon powder shotcrete, composite reinforcing compact agent, and low-cement castable have passed technical appraisal from the provincial, provincial and municipal levels, and are applied in many projects. in...
