Multi-element solid waste concrete block and preparation method thereof
The invention discloses a multi-element solid waste concrete block and a preparation method thereof, and belongs to the field of building materials. The multi-element solid waste concrete block is prepared from phosphogypsum-based cement, recycled coarse aggregate, recycled fine aggregate, water, plant fibers and a water reducing agent in percentage by weight. The phosphogypsum-based cement is composed of phosphogypsum, slag, steel slag, limestone and a small amount of Portland cement clinker. The prepared gypsum concrete is vibrated and uniformly stirred, then put into a pressure forming machine, and prepared into a small hollow concrete block by means of extruding, vibrating, forming, demolding and curing. The compressive strength and the comprehensive performance of the prepared building block are guaranteed, the national waste resource comprehensive utilization industrial policy is met, the problem that construction waste and industrial waste residues are difficult to dispose is solved, and the building block has important practical significance and remarkable application value.
本发明公开了一种多元固废混凝土砌块及其制备方法，属于建筑材料领域。是由磷石膏基水泥、再生粗骨料、再生细骨料、水、植物纤维、减水剂按重量百分比组成。所述的磷石膏基水泥由磷石膏、矿渣、钢渣、石灰石和少量硅酸盐水泥熟料组成。将制备的石膏混凝土振捣搅拌均匀后放到压力成型机中，经挤压振动成型、脱模养护后制备成混凝土小型空心砌块。制备出来的砌块抗压强度及其综合性能得到保证并符合国家废弃物资源综合利用产业政策，解决了建筑废弃物、工业废渣处置困难的问题，具有重要的现实意义和显著的应用价值。
