Freeze-thaw resistant engineering residue soil baking-free brick and preparation method thereof
The invention discloses a freeze-thaw resistant building residue soil baking-free brick and a preparation method thereof. The freeze-thaw resistant building residue soil baking-free brick is prepared from cement, engineering residue soil, building regenerated stone powder and a modifying additive, and the modifying additive is prepared from fly ash, silica fume, sodium hydroxide and a water reducing agent. The preparation process of the modified engineering residue soil baking-free brick with the freeze-thaw resisting function is simple to operate and 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, production time is saved, carbon emission is reduced, the durability of the residue soil brick is prominently optimized by adding the modifying additive, the compressive strength of the residue soil brick is increased, and the produced baking-free brick can be used for retaining and separating some non-bearing structures and can be used in municipal pavements and some low-bearing municipal engineering.
本发明公开了一种抗冻融建筑渣土免烧砖及其制备方法，所述一种抗冻融建筑渣土免烧砖的制造原料包括水泥、工程渣土、建筑再生石粉和改性外加剂，所述改性外加剂的制造原料包括粉煤灰、硅灰、氢氧化钠和减水剂。本发明采用具备抗冻融功能的改性工程渣土免烧砖制备工艺操作简单，可以用来进行产业化生产，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，并且改性外加剂的添加突出优化了渣土砖的耐久性能，并且增加了渣土砖的抗压强度，而且本发明生产的免烧砖可以用于一些非承重结构的围挡和分隔，其在市政路面和一些低承载的市政工程中均可加以利用。
