The invention discloses mud-resistant slump-retaining building solid waste recycled aggregate concrete and a preparation method thereof. The building solid waste recycled aggregate concrete is prepared from, by weight, 105-115 parts of building solid waste recycled aggregate, 73-81 parts of natural gravel, 53-59 parts of a mineral mixture, 64-72 parts of cement, 120-128 parts of water, 23-27 partsof an enhancer and 19-24 parts of a water reducing agent. The mineral mixture comprises 16 parts of fly ash, 15 parts of zeolite, 11 parts of nano silicon dioxide, 9 parts of montmorillonite and 7 parts of modified polypropylene fibers. The enhancer is mainly prepared by reaction of polyvinyl alcohol, lactic acid and sodium fluosilicate. The building solid waste is subjected to multi-stage sorting and crushing to obtain recycled aggregate; the recycled aggregate is treated by phosphoric acid and the enhancer and then mixed with the mineral mixture, the water, the natural gravel and the cementto prepare the building solid waste recycled aggregate concrete which is high in strength, low in porosity, low in water absorption, resistant to mud and resistant to slump.
本发明公开了一种耐泥保坍型建筑固废再生骨料混凝土及其制备方法，所述建筑固废再生骨料混凝土各原料组分如下，按重量份数计，建筑固废再生骨料105‑115份、天然碎石73‑81份、矿物混合料53‑59份、水泥64‑72份、水120‑128份、强化剂23‑27份、减水剂19‑24份。其中矿物混合料包括粉煤灰16份、沸石15份、纳米二氧化硅11份、蒙脱土9份、改性聚丙烯纤维7份。强化剂主要由聚乙烯醇、乳酸、氟硅酸钠反应制得。建筑固废经多级分选粉碎得到再生骨料，再生骨料经磷酸、强化剂处理后，与矿物混合料、水、天然碎石、水泥拌合，制得强度高、孔隙率低、吸水性低、且耐泥保坍的建筑固废再生骨料混凝土。
