High-polymer environment-friendly recycled concrete and preparation method thereof
The invention relates to the field of concrete, and particularly discloses high-polymer environment-friendly recycled concrete. The high-polymer environment-friendly recycled concrete comprises the following components in parts by weight: 980-1050 parts of coarse aggregate, 630-680 parts of fine aggregate, 350-380 parts of cement, 60-80 parts of slag powder, 110-140 parts of fly ash, 155-170 partsof water and 2-5 parts of a polycarboxylate superplasticizer, wherein the coarse aggregate is surface-coated with a lac film. The high-polymer environment-friendly recycled concrete has the advantages that the workability of the recycled concrete can be improved, and meanwhile, the influence on concrete setting time is reduced.
本申请涉及混凝土的领域，具体公开了一种高聚物环保再生混凝土，包括以下重量份的组分：粗骨料980‑1050份，细骨料630‑680份，水泥350‑380份，矿渣粉60‑80份，粉煤灰110‑140份，水155‑170份，聚羧酸减水剂2‑5份，其中，粗骨料为表面包裹有紫胶膜的再生粗骨料。本申请的高聚物环保再生混凝土具有能在提高再生混凝土的和易性的同时，减小对混凝土凝结时间的影响的优点。
