Composite micro-powder partially replacing cement and cement-based material
The invention provides composite micro-powder partially replacing cement and a cement-based material, and belongs to the field of building materials. The mass coefficients of the water-quenched manganese slag micro-powder and the slag micro-powder meet the requirements (K is greater than or equal to 1.2) in GB/T 203-2008; the gelling activity brought by a large amount of vitreous bodies containedin the water-quenched manganese slag and the furnace slag is utilized, and the comprehensive utilization of the water-quenched manganese slag and the furnace slag is realized; meanwhile, the use of water-quenched manganese slag micro powder and slag micro powder is limited, the micro powder is obtained by refining particles through mechanical grinding, the inert glass state inside the particle canbe destroyed, then the large defect is generated on the surface and the particle reaction activity is increased; and the beneficial environment is provided for the further dissociation of the silicanetwork and the formation of calcium silicate hydrate, ettringite and other hydration products through the activation effect of the gypsum as the activator.
本发明提供了一种部分替代水泥的复合微粉及水泥基材料，属于建筑材料领域。本发明中水淬锰渣微粉与炉渣微粉的质量系数均符合GB/T 203‑2008中的要求(K≥1.2)，利用了水淬锰渣和炉渣所含大量玻璃体带来的胶凝活性，实现了水淬锰渣和炉渣的综合利用，同时限定了使用水淬锰渣微粉与炉渣微粉，微粉是经过机械粉磨使颗粒细化得到的，能够破坏颗粒内部的惰性玻璃态，使其表面产生较大的缺陷，利于颗粒反应活性的增加，同时通过石膏作为激发剂的活化作用，为进一步硅氧网络的解离和水化硅酸钙、钙矾石等水化产物的形成提供有利的环境。
