Ultrahigh-strength red mud light material and preparation method thereof
The invention relates to an ultrahigh-strength red mud light material and a preparation method thereof, and the method comprises the following steps: crushing and ball-milling red mud, uniformly mixing red mud micro powder, slag micro powder, fly ash and slaked lime powder, and adding sodium hydroxide and liquid sodium silicate. The purpose of light weight by using ultrahigh-strength water absorption of red mud particles and adopting an ultrahigh liquid-solid ratio mode is achieved, meanwhile, through the interaction among the red mud micro powder, the slag micro powder, the fly ash and the slaked lime powder, the polymerization reaction activity among the materials is fully exerted, so that preparation of the ultrahigh-strength red mud light material is realized. The red mud light material is prepared by taking red mud as a main raw material, resource recycling of wastes is realized, and meanwhile, the red mud light material has the characteristics of low preparation cost and ultrahigh mechanical properties.
一种超高强赤泥轻质材料与制备方法，该方法首先将赤泥进行破碎与球磨，然后将赤泥微粉、矿渣微粉、粉煤灰与熟石灰粉混合均匀，再加入氢氧化钠与液态硅酸钠，利用赤泥颗粒的超高强吸水性，采取超高液固比的方式达到轻质的目的，同时通过赤泥微粉、矿渣微粉、粉煤灰与熟石灰粉之间的交互作用，充分发挥材料之间的聚合反应活性，从而实现超高强赤泥轻质材料的制备。该赤泥轻质材料的制备以赤泥为主要原材料，实现了废弃物的资源化回收利用，同时具有制备成本低，超高强力学性能的特点。
