Recycled coarse aggregate concrete and preparation method thereof
The invention discloses recycled coarse aggregate concrete and a preparation method thereof, and specifically relates to the technical field of building materials. The recycled coarse aggregate concrete comprises the following components in parts by weight: a coarse aggregate composition, cement, blast furnace slag, natural river sand, waste plastics, a water reducing agent and water, wherein thecoarse aggregate composition comprises natural coarse aggregate and recycled coarse aggregate; the particle size of the recycled coarse aggregate is 5 mm to 20 mm; the mass of the coarse aggregate composition is less than 50% of the total mass of the recycled coarse aggregate; and the recycled coarse aggregate is subjected to impurity removal, magnetic separation, crushing, screening, leaching anddrying treatment. According to the invention, the recycled coarse aggregate, the blast furnace slag and the waste plastics are used as raw materials to prepare the recycled coarse aggregate concrete,so the wastes can be effectively utilized; basic strength is realized; meanwhile, the cost of a newly-built project can be reduced.
本发明公开了一种再生粗骨料混凝土及其制备方法，具体涉及建筑材料的技术领域，由以下组分按重量份数组成：粗骨料组合物、水泥、高炉矿渣、天然河砂、废塑料、减水剂与水；所述粗骨料组合物包括天然粗骨料与再生粗骨料；所述再生粗骨料的粒径为5mm‑20mm；所述粗骨料组合物的质量小于再生粗骨料总质量的50％；所述再生粗骨料经除杂、磁选、粉碎、筛分、淋洗与干燥处理。本发明中使用了再生粗骨料、高炉矿渣与废塑料作为原料来制备再生粗骨料混凝土，可以有效的进行废物利用，在实现基本强度的同时又能降低新建工程的成本。
