Novel recycled concrete mortar and preparation method thereof
The invention discloses novel recycled concrete mortar and a preparation method thereof. The novel recycled concrete mortar comprises the following components in parts by weight: 89-126 parts of a recycled aggregate, 48-86 parts of a new aggregate, 78-135 parts of Portland cement, 32-56 parts of nano silicon dioxide, 35-65 parts of dimethyl carbonate, 20-45 parts of methyl silicone oil, 33-49 parts of polyethylene glycol, 10-23 parts of a water reducing agent, 8-16 parts of a curing filler, 55-68 parts of a reinforcing filler, 30-58 parts of an anti-cracking agent and 500-1200 parts of water.According to the invention, the generation of micro cracks in the recycled concrete can be effectively reduced, so that the porosity of the recycled concrete is effectively reduced, and the compressive strength, impermeability and other properties of the recycled concrete are improved.
本发明公开了一种新型再生混凝土砂浆及其制备方法，其技术要点在于：原料按重量份包括以下组分：再生骨料89‑126份，新骨料48‑86份，硅酸盐水泥78‑135份，纳米二氧化硅32‑56份，碳酸二甲酯35‑65份，甲基硅油20‑45份，聚乙二醇33‑49份，减水剂10‑23份，固化填料8‑16份，增强填料55‑68份，抗开裂剂30‑58份，水500‑1200份。本发明可以有效减少再生混凝土内部的微细裂缝的产生，进而有效降低再生混凝土的孔隙率，提高再生混凝土的抗压强度、抗渗性等性能。
