Multi-source solid waste low-carbon regenerated mortar and preparation method thereof
The invention discloses multi-source solid waste low-carbon regenerated mortar and a preparation method thereof, and the multi-source solid waste low-carbon regenerated mortar comprises the following components in parts by weight: 127-152 parts of all-component regenerated sand powder, 27-83 parts of a cementing material, 0-5 parts of wood flour, 1-1.5 parts of NaOH, 5-9 parts of sodium silicate and 16-25 parts of water. The invention provides a co-processing technology of multi-source solid wastes such as all-component regenerated sand powder, red mud and waste wood powder, cement is replaced by a low-carbon cementing material, natural fine aggregate is replaced by the all-component regenerated sand powder, NaOH in an exciting agent is replaced by soluble alkaline components in the red mud to prepare the low-carbon regenerated mortar, and the deformability and toughness of the low-carbon regenerated mortar are improved by adopting the wood powder. According to the method, carbon emission can be effectively reduced, ecological potential safety hazards caused by the industrial solid waste red mud lixivium are avoided, economic and environment-friendly double benefits are achieved, and a foundation is laid for application and development of green, ecological and low-carbon building materials.
本发明公开了一种多源固废低碳再生砂浆及其制备方法，按重量份数计，材料的组分为：全组分再生砂粉127‑152份、胶凝材料27‑83份、木粉0‑5份、NaOH 1‑1.5份、硅酸钠5‑9份、水16‑25份。本发明提出全组分再生砂粉、赤泥、废旧木粉等多源固废协同处置技术，利用低碳胶凝材料替代水泥，全组分再生砂粉替代天然细骨料，以赤泥中的可溶性碱性组分替代激发剂中的NaOH制备低碳再生砂浆，采用木粉提高其变形能力及韧性。利用本发明可有效降低碳排放，解决了工业固废赤泥浸出液带来的生态安全隐患，具有经济与环保的双重效益，为绿色、生态、低碳建筑材料应用和发展奠定基础。
