Alkali-activated recycled red brick micro-powder synergistic slag-based recycled concrete and preparation method thereof
The invention discloses alkali-activated recycled red brick micro-powder synergistic slag-based recycled concrete and a preparation method thereof. The alkali-activated recycled red brick micro-powdersynergistic slag-based recycled concrete is prepared from the following components in percentage by mass: 10%-30% of recycled red brick micro-powder, 10%-30% of slag, 5%-15% of fly ash, 15%-35% of natural river sand, 35%-55% of recycled coarse aggregate, 0.1%-2% of sodium hydroxide solid, 1%-5% of water glass, 0.1%-2% of sodium carbonate and 10%-20% of water. The water-binder ratio is 0.40-0.52 (the mass sum of the regenerated red brick micro powder, the slag and the fly ash in the mass ratio of the water), and the water comprises water contained in the water glass and additional water. Compared with ordinary cement recycled concrete, the strength of the alkali-activated recycled red brick micro-powder synergistic slag-based recycled concrete is obviously improved, meanwhile, solid wasteis comprehensively utilized, meanwhile, good working performance such as fluidity and workability can be achieved, the alkali-activated recycled red brick micro-powder synergistic slag-based recycledconcrete is more efficient and environmentally friendly, and resources are saved.
本发明公开了一种碱激发再生红砖微粉协同矿渣基的再生混凝土及其制备方法。所述的碱激发再生红砖微粉协同矿渣基的再生混凝土，由再生红砖微粉、矿渣、粉煤灰、天然河砂、再生粗骨料、氢氧化钠固体、水玻璃、碳酸钠和水按质量百分比10％～30％:10～30％:5％～15％:15％～35％:35％～55％:0.1％～2％:1％～5％:0.1％～2％：10％～20％制备而成，水胶比(水的质量比上再生红砖微粉、矿渣和粉煤灰的质量和)0.40～0.52，其中水包括水玻璃中所含的水以及外加水。该碱激发再生红砖微粉协同矿渣基的再生混凝土相对于普通水泥再生混凝土来说强度得到了明显提升，同时在综合利用固体废弃物的同时能够达到较好的流动性、和易性等工作性能，更加高效环保，节约资源。
