Recycled aggregate perforated brick and preparation method thereof
The invention discloses a recycled aggregate perforated brick and a preparation method thereof, and relates to the technical field of building material production. When the recycled aggregate porous brick is prepared, the self-made capillary crystalline material is firstly used for pretreating the recycled aggregate, and then the porous brick is prepared; wherein the self-made capillary crystalline material is prepared by mixing Portland cement, polyamide, calcium carbonate and calcium chloride; the self-made capillary crystalline material fills pores and cracks, so that the crack extension resistance of the recycled aggregate is enhanced, the water absorption capacity of the recycled aggregate is reduced, the strength of the porous brick is enhanced, the water absorption capacity of the recycled aggregate is reduced, and the strength of the porous brick is enhanced; and when the porous brick is prepared, firstly, the aggregate is pre-sintered in an electric field, pressurization is carried out while pre-sintering is carried out, in the sintering process, under the action of the electric field, dendritic polyamide extends in the pore direction and supports mutually communicated pores, then the porous brick is prepared, and thus, the water permeability of the porous brick is enhanced.
本发明公开了一种再生骨料多孔砖及其制备方法，涉及建筑材料生产技术领域。本发明在制备再生骨料多孔砖时，先用自制渗透结晶材料对再生骨料进行预处理，再进行多孔砖的制备；自制渗透结晶材料由硅酸盐水泥、聚酰胺、碳酸钙和氯化钙混合制得，自制渗透结晶材料将孔隙与裂纹填充，增强再生骨料的抗裂缝延展的能力，减少了再生骨料的吸水量，增强多孔砖的强度减少了再生骨料的吸水量，增强多孔砖的强度；制备多孔砖时，先将集料在电场中进行预烧结，预烧结的同时进行加压，烧结时在电场的作用下，树枝状的聚酰胺向孔隙方向伸展，将相互连通的孔隙支撑，再进行多孔砖的制备，增强了多孔砖的透水性。
