Green low-carbon high-performance sprayed concrete using active regenerated micro-powder, and preparation method and construction process of green low-carbon high-performance sprayed concrete
The invention relates to the field of sprayed concrete, in particular to green low-carbon high-performance sprayed concrete using active regenerated micro powder and a preparation method and a construction process of the green low-carbon high-performance sprayed concrete. The sprayed concrete is prepared from the following components in parts by weight: 300 to 350 parts of cement, 50 to 80 parts of active regenerated micro powder, 60 to 120 parts of early strength type mineral admixture, 20 to 40 parts of rubber powder, 10 to 20 parts of hydrophobic compacting agent, 700 to 800 parts of coarse aggregate and 800 to 900 parts of fine aggregate, the mixing amount of the water reducing agent is 0.8%-1.2% of the mass of the cementing material, and the mixing amount of the fluoride-free alkali-free accelerator is 6%-9% of the mass of the cementing material; wherein the active regenerated micro powder is composed of multi-component isomeric alcohol amine and regenerated micro powder, and the dosage of the multi-component isomeric alcohol amine is 0.1%-0.5% of the mass of the cementing material. The cement consumption of the sprayed concrete can be reduced, and the requirement for high performance of the sprayed concrete is met.
本申请涉及喷射混凝土领域，更具体地说，它涉及一种使用活性再生微粉的绿色低碳高性能喷射混凝土及其制备方法、施工工艺；喷射混凝土原料按重量份包括以下组分：水泥300‑350份，活性再生微粉50‑80份，早强型矿物掺合料60‑120份，橡胶粉20‑40份，疏水密实剂10‑20份，粗骨料700‑800份，细骨料800‑900份；减水剂，掺量为胶凝材料质量的0.8％～1.2％，无氟无碱速凝剂，掺量为胶凝材料质量的6％～9％；其中，所述活性再生微粉由多元异构醇胺和再生微粉组成，所述多元异构醇胺的用量为胶凝材料质量的0.1％～0.5％。本申请可以降低喷射混凝土的水泥用量并实现喷射混凝土高性能化的需求。
