Green low-carbon recycled concrete and preparation method thereof
The invention relates to the field of building materials, and particularly discloses green low-carbon recycled concrete and a preparation method thereof. The green low-carbon recycled concrete is prepared from the following raw materials in parts by weight: 3-6 parts of slag, 30-50 parts of modified recycled sand, 8-10 parts of recycled powder, 40-50 parts of cement, 5-8 parts of water-soluble phenolic resin, 0.2-0.5 part of an additive, 1-3 parts of a dispersing agent, 5-7 parts of water glass and 60-80 parts of water, and the modified recycled sand is obtained by carbonizing and modifying after being soaked in a modifying solution; the preparation method comprises the following steps: uniformly stirring the slag, the regenerated powder, the cement, the additive and the water glass to obtain dry powder, adding the water glass and half of water, and continuously stirring and uniformly mixing to obtain a mixture for later use; and heating water to 50-70 DEG C, adding the weighed modified regenerated sand, water-soluble phenolic resin and dispersant, stirring for 3-5 minutes, adding the mixture, and continuously stirring for 3-5 minutes to obtain the green low-carbon regenerated concrete. The composition has the advantages of high compressive strength and good durability.
本申请涉及建筑材料领域，具体公开了一种绿色低碳再生混凝土及其制备方法。一种绿色低碳再生混凝土，包括如下重量份原料：矿渣3‑6份、改性再生砂30‑50份、再生粉料8‑10份、水泥40‑50份、水溶性酚醛树脂5‑8份、外加剂0.2‑0.5份、分散剂1‑3份、水玻璃5‑7份以及水60‑80份，所述改性再生砂为经过改性溶液浸渍后碳化改性得到；其制备方法为：将矿渣、再生粉料、水泥、外加剂以及水玻璃搅拌均匀，得到干粉料后加入水玻璃和一半水继续搅拌混合均匀，得到混合料备用；将水加热到50‑70℃后加入称量好的改性再生砂、水溶性酚醛树脂以及分散剂搅拌3‑5min后，加入混合料继续搅拌3‑5min后，得到绿色低碳再生混凝土。本申请的组合物具有抗压强度高、耐久性好的优点。
