Modified engineering muck baking-free brick and preparation process thereof
The invention discloses a modified engineering muck baking-free brick and a preparation process thereof. The modified engineering muck baking-free brick is prepared from a modified admixture, cement, engineering muck and building regenerated stone powder, wherein the modified admixture is prepared from silica fume, sodium silicate, sodium hydroxide and a water reducing agent, and the modified admixture is prepared from the following materials in parts by mass: 40 parts of silica fume, 13.33 parts of sodium silicate, 13.33 parts of sodium hydroxide and 33.33 parts of a water reducing agent. The preparation process for manufacturing the modified engineering muck baking-free brick is simple to operate, the manufacturing materials for manufacturing the modified engineering muck baking-free brick are simple and easy to obtain, the modified engineering muck baking-free brick can be used for industrial production, and compared with a traditional fired brick, the prepared baking-free brick has the advantages that environmental pollution is reduced, the production time is saved, carbon emission is reduced, construction waste such as engineering muck is effectively recycled, the compressive strength of the muck brick is enhanced to a certain extent through the added modified admixture, and the durability of the muck brick is improved.
本发明公开了一种改性工程渣土免烧砖及其制备工艺，一种改性工程渣土免烧砖的制造材料包括改性外加剂、水泥、工程渣土和建筑再生石粉，所述改性外加剂的制造材料包括硅灰、硅酸钠、氢氧化钠和减水剂，所述改性外加剂制造材料的质量份数为硅灰40份、硅酸钠13.33份、氢氧化钠13.33份和减水剂33.33份。本发明制造改性工程渣土免烧砖制备工艺操作简单，并且制造改性工程渣土免烧砖的制造材料简单易得，可以用来进行产业化生产，并且制备出免烧砖与传统烧制砖相比，减少了环境污染，节约了生产时间，降低了碳排放量，并且对工程渣土等建筑垃圾进行有效回收利用，而加入的改性外加剂一定程度上增强了渣土砖的抗压强度，并使渣土砖的耐久性能得到提升。
