Silicon-manganese water-quenched slag concrete
Physical treatment and chemical modification are carried out on silicon-manganese water-quenched slag, an excitant, quartz tailings, sand, stone and other components are comprehensively utilized, andthe advantages are complementary. According to the invention, the silicon-manganese water-quenched slag contains high vitreous body, potential hydraulic property and volcanic ash activity, and the activity is excited by an exciting agent which is formed by mixing lime and sodium carbonate, so that active substances are generated in the secondary reaction of cement, and the strength of the materialis improved. The silicon-manganese water-quenched slag partially replaces cement, cement consumption is reduced, the gelling effect of the slag is used to solidify heavy metal, the slag is environmentally friendly, gaps among particles are filled, and the compactness is high. The silica content of the quartz tailings is high, the hydration reaction of silicate is promoted, secondary utilization of natural resources is achieved, the radioactivity of part of substitute sand is low, and the manufacturing cost is reduced. Compared with reference concrete, the prepared concrete has the advantagesthat the mechanical property is improved to a certain extent, and the concrete has good impermeability, freezing resistance, dry shrinkage resistance, durability and the like and can be widely appliedto engineering.
本发明对硅锰水淬渣进行了物理处理和化学改性，综合利用激发剂、石英尾渣、砂、石等组分，优势互补。本发明利用硅锰水淬渣中含较高的玻璃体、潜在水硬性和火山灰活性，通过石灰和纯碱混合的激，发剂激发活性，在水泥二次反应中生成活性物质，使材料强度得以提升。硅锰水淬渣部分代替水泥，减少水泥使用，其胶凝效果固化重金属绿色环保，填补颗粒间空隙，密实度高。本发明中石英尾渣的二氧化硅含量较高，促进硅酸盐水化反应，实现自然资源二次利用，部分替代砂放射性低，制作成本缩减。本发明制得的混凝土力学性能较基准混凝土有一定提升，具有良好的抗渗性、抗冻性、抗干缩性、耐久性等，可广泛用于工程中。
