Preparation method of recycled aggregate concrete applied to wallboards
The invention discloses a preparation method of recycled aggregate concrete applied to wallboards, belonging to the technical field of recycled aggregate concrete.The preparation method comprises the following steps: taking the following raw materials in parts by weight: 700-780 parts of medium sand, 30-90 parts of recycled aggregate, 920-970 parts of rubble, 110-150 parts of fine stone, 290-350 parts of cement, 20-50 parts of fly ash and 120-180 parts of water; the recycled aggregate concrete is obtained by mixing the raw materials, adding 2.5-3.3 parts of an additive, and stirring and mixing. Pouring the recycled aggregate concrete into the wallboard manufacturing mold, and curing the recycled concrete; according to the invention, the recycled coarse aggregate with the weight being one tenth of that of the recycled fine aggregate is used, and the recycled coarse aggregate is mixed with the raw materials to prepare the recycled aggregate concrete suitable for the wallboard, so that the manufacturing cost of the wallboard is greatly reduced.
本发明公开了一种应用于墙板的再生骨料混凝土的制备方法，属于再生骨料混凝土技术领域，包括以下步骤：按重量份计取如下原料：中砂700‑780份，再生骨料30‑90份，粗石920‑970份，细石110‑150份，水泥290‑350份，粉煤灰20‑50份，水120‑180份；将各原料混合，并加入外加剂2.5‑3.3份进行搅拌混合获得再生骨料混凝土；将再生骨料混凝土倒入墙板制作模具内，进行再生混凝土的养护；本发明通过使用份量为再生细骨料十分之一的再生粗骨料，并将再生粗骨料与各原料进行混合，制备成适用于墙板的再生骨料混凝土，大大降低了墙板的制作成本。
