Preparation method of recycled fine aggregate concrete
The invention provides a preparation method of recycled fine aggregate concrete, the recycled fine aggregate concrete is prepared from the following raw materials in parts by weight: 300-700 parts of coarse aggregate, 700-900 parts of recycled fine aggregate, 110-230 parts of cement, 200-500 parts of water, 3-15 parts of polycarboxylate superplasticizer and 50-80 parts of mineral powder, the recycled fine aggregate is shaped waste concrete particles, and the recycled fine aggregate is shaped. Therefore, the strength of the invention can be improved.
本发明提供一种再生细骨料混凝土的制备方法，所述再生细骨料混凝土由以下重量分的原料制成：粗骨料300～700份、再生细骨料700～900份、水泥110～230份、水200～500份、聚羧酸高效减水剂3～15份、矿粉50～80份，所述再生细骨料为整形后的废弃混凝土颗粒，通过对再生细骨料进行整形，从而能够提高本发明的强度。
