Anti-crack recycled concrete and manufacturing method thereof
The invention belongs to the technical field of concrete, and particularly relates to anti-crack recycled concrete. The anti-crack recycled concrete is prepared from 30 parts of slag cement, 30 partsof coal ash, 12 parts of recycled coarse aggregate, 8 parts of recycled fine aggregate, 6 parts of sodium silicate mineral powder, 6 parts of calcium silicate mineral powder and 8 parts of a recycledcementing mixture. The recycled cementing mixture can improve the mutual bonding and mixing effects between the recycled coarse aggregate and the cement and between the recycled fine aggregate and thecement, so that the fission resistance and the pressure resistance of the recycled concrete are improved; and meanwhile, the recycled cementing mixture can improve the efficient utilization of wastesand reduce the waste of resources. The invention further discloses a preparation method of the anti-crack recycled concrete. The preparation method comprises the following steps: S1, extracting aggregate; S2, preparing gel; S3, hydrating silicon salt; S4, preparing slurry; and S5, mixing and preparing. The phenomenon that the surface or the interior of the untreated recycled coarse aggregate contains a large amount of micro powder, so that the contact between the recycled coarse aggregate and slurry is poor integrally is prevented.
本发明属于混凝土技术领域，具体的说是一种抗裂再生混凝土；该抗裂再生混凝土组成为：矿渣水泥30份、粉煤灰30份、再生粗骨料12份、再生细骨料8份、硅酸钠矿粉6份、硅酸钙矿粉6份和再生胶凝混合物8份；再生胶凝混合物不仅能够提高再生粗骨科和再生细骨料与水泥之间的相互粘结混合效果，进而提高再生混凝土的抗裂变和抗压能力；同时再生胶凝混合物能够提高废弃物的高效利用，减少资源的浪费现象；本发明目的二公开了一种抗裂再生混凝土的制备方法，S1：骨料提取；S2：凝胶制备：S3:水化硅盐：S4：泥浆制备；S5：混合制备；防止未经处理后的再生粗骨料表面或内部含有大量的微粉，导致再生粗骨料与泥浆接触整体较差的现象。
