Dry-mixed common ground mortar based on building solid waste recycled fine aggregate
The invention discloses dry-mixed common ground mortar based on a building solid waste recycled fine aggregate. The dosage mixing ratio (kg/t) of each component is as follows: 140 to 190 kg/t of 42.5-grade ordinary Portland cement, 50 kg/t of second-grade fly ash, 750 to 800 kg/t of recycled fine aggregate, 0.8 to 1 kg/t of hydroxypropyl methyl cellulose, 8 to 10 kg/t of redispersible latex powder, 0.16 to 0.2 kg/t of A defoaming agent and 1.5 to 2.5 kg/t of recycled fiber. the recycled fine aggregate is formed by crushing waste concrete, the particle size of the recycled fine aggregate is 4.75 mm or below, the content of particles with the particle size of 2.36-4.75 mm is 10-15%, and the content of particles with the particle size of 0.075-2.36 mm is 70-80%. According to the invention, the building concrete wastes are turned into wealth to replace natural sand, so that not only is the natural environment protected, but also the cost of the mortar is reduced.
本发明公开了一种基于建筑固废再生细骨料的干混普通地面砂浆，各组分用量配合比(kg/t)为：42.5级普通硅酸盐水泥140‑190，二级粉煤灰50，再生细骨料750‑800，羟丙基甲基纤维素0.8～1、可再分散乳胶粉8～10、消泡剂0.16～0.2、再生纤维1.5～2.5。所述再生细骨料是由废弃混凝土破碎而成，粒径在4.75mm以下，其中粒径2.36‑4.75mm的颗粒含量10‑15％，粒径0.075‑2.36mm的颗粒含量70‑80％。本发明利用建筑混凝土废料“变废为宝”替代天然砂，不仅保护了自然环境，还降低了砂浆的成本。
