Pressing method brick making process of building waste mud
The embodiment of the invention discloses a pressing method brick making process of building waste mud. The process comprises the following steps: S100: carrying out sand separation and sand washing treatment on the building mud to obtain sand-removed mud; S200, adding a flocculating agent into the sand-removed mud quickly stirring until tiny solid particles in the mud are condensed into flocculent agglomerates with larger volumes, standing and removing supernatant liquid; S300, dehydrating the flocculated mud to obtain a dehydrated mud cake with the water content of less than or equal to 35%;S400, preparing materials according to the following materials in percentage by mass: 80%-90% of dehydrated mud cake, 12%-17% of cement and 2%-3% of water reducing agent; S500, adding water into theingredients and stirring to obtain a brick making raw material; and S600, pressing the brick making raw material to obtain a finished product brick. According to the brick making process of the building waste mud, the treatment cost of the waste mud can be reduced, the problem of environmental pollution caused by the waste mud is solved and the recycling value of the waste mud is achieved.
本发明实施例公开了一种建筑废泥浆的压制法制砖工艺，包括以下步骤：S100：对建筑泥浆进行分砂洗砂处理，得到脱砂后的泥浆；S200：在脱砂后的泥浆中加入絮凝剂，快速搅拌至泥浆中的微小固体颗粒凝聚成体积较大的絮状团块，静置，除去上层清液；S300：对经过絮凝处理的泥浆进行脱水，并得到含水量小于或等于35％的脱水泥饼；S400：根据以下配料质量百分比进行配料：脱水泥饼80％‑90％、水泥12％‑17％和减水剂2％‑3％；S500：对配料进行加水搅拌，并得到制砖原料；S600：用所述制砖原料并压制得到成品砖。本发明的建筑废泥浆制砖工艺可以减少了废泥浆的处理费用，解决了废泥浆造成环境污染的问题，并且实现了废泥浆再利用的价值。
