Alkali-activated clinker-free refractory self-leveling concrete and preparation method thereof
Alkali-activated clinker-free refractory self-leveling concrete is prepared from the following components in parts by mass: 225 to 550 parts of cementing material, 10 to 20 parts of alkali activator, 1000 to 1200 parts of coarse aggregate, 800 to 1100 parts of fine aggregate, 150 to 200 parts of water and 0.2 to 0.5 part of additive. The invention further comprises a preparation method of the concrete. The preparation method comprises the following steps: 1, crushing the steel slag, the waste glass and the phosphorus slag; 2, grinding the copper tailings to obtain coarse aggregate and fine aggregate; 3, grinding the crushed material in the step 1; and 4, adding an alkali activator, water, an additive, coarse aggregate and fine aggregate into the grinding material obtained in the step 3, and mixing and stirring to obtain the clinker-free refractory self-leveling concrete. According to the invention, solid wastes are fully utilized, the use of cement clinker is avoided, and the efficient utilization of solid waste resources is realized.
本发明一种碱激发无熟料耐火自流平混凝土，其质量份组成为：胶凝材料225～550份、碱激发剂10～20份、粗集料1000～1200份、细集料800～1100份、水150～200份、外加剂0.2～0.5份。本发明还包括该混凝土的制备方法，包括以下一，对钢渣、废玻璃、磷渣进行破碎；二，对铜尾矿进行研磨获取粗骨料和细骨料；三，对步骤一中的破碎料研磨；四，将步骤三中得到的研磨料加入碱激发剂、水、外加剂、粗骨料、细骨料进行混合搅拌制得无熟料耐火自流平混凝土。本发明充分利用了固体废弃物，避免了水泥熟料的使用，实现固废资源的高效利用。
