Regenerated self-leveling mortar as well as preparation method and application thereof
The invention provides regenerated self-leveling mortar as well as a preparation method and application thereof, and belongs to the technical field of building materials. Waste pure concrete sand and waste aerated concrete micro powder are used as recycled aggregates, Portland cement, high-alumina cement, silica fume and semi-hydrated gypsum are used as cementing materials, and redispersible latex powder, magnesium aluminum silicate, a polycarboxylic acid water reducing agent, a polyether defoaming agent and a slump retaining agent are used as functional auxiliaries. The production cost of the regenerated self-leveling mortar can be remarkably reduced, meanwhile, the regenerated self-leveling mortar has the advantages of being high in bonding strength, high in flexural and compressive strength, good in flowing property and small in shrinkage rate, and resource utilization of building waste is achieved.
本发明提供了一种再生自流平砂浆及其制备方法和应用，属于建筑材料技术领域。本发明以废弃纯混凝土砂和废弃加气混凝土微粉为再生骨料，以硅酸盐水泥、高铝水泥、硅灰和半水石膏为胶凝材料，以可再分散性乳胶粉、硅酸铝镁、聚羧酸减水剂、聚醚消泡剂和保坍剂为功能性助剂，能够显著降低再生自流平砂浆的生产成本，同时所述再生自流平砂浆具有粘结强度高、抗折抗压强度高、流动性能好以及收缩率小的优点，实现了建筑废弃物资源化利用。
