Baking-free brick
The invention relates to a baking-free brick, and belongs to the technical field of waste treatment and resource utilization. The baking-free brick is mainly prepared from water and the following raw materials: sludge baking-free granular materials, cement and a water reducing agent, the sludge unfired granular material is a sludge unfired granular aggregate or a composition of the sludge unfired granular aggregate and gravel; the sludge unfired granular aggregate is prepared from the following components in percentage by mass: 50%-71% of fermented sludge based on dry weight, 15%-25% of cement, 5%-15% of calcined gypsum and/or quick lime and 4%-6% of sodium silicate. The sludge baking-free granular aggregate in the baking-free brick takes the fermented sludge as a main raw material, the sludge utilization rate is high, the cement, the calcined gypsum and/or the quick lime and the sodium silicate are supplemented, and the baking-free brick prepared from the sludge baking-free granular aggregate has high compressive strength, and the baking-free brick prepared from the sludge baking-free granular aggregate has high compressive strength and can prevent harmful substances from being dissolved out and entering the environment.
本发明涉及一种免烧砖，属于废弃物处理与资源利用技术领域。本发明的免烧砖主要由水和以下原料制成：污泥免烧颗粒粒料、水泥、减水剂；所述污泥免烧颗粒粒料为污泥免烧颗粒骨料或污泥免烧颗粒骨料、砂石的组合物；所述污泥免烧颗粒骨料由以下质量分数的组分制成：以干重计发酵污泥50％～71％、水泥15％～25％、熟石膏和/或生石灰5％～15％、硅酸钠4％～6％。本发明免烧砖中的污泥免烧颗粒骨料以发酵污泥为主要原料，污泥利用率高，辅以水泥、熟石膏和/或生石灰、硅酸钠，具有较高的抗压强度，由该污泥免烧颗粒骨料制成的免烧砖，抗压强度较高，并且能够防止有害物质溶出进入环境。
