High polymer environment-friendly recycled concrete and preparation method thereof
The invention discloses high polymer environment-friendly recycled concrete and a preparation method thereof, and relates to the technical field of concrete. The problem that cracks exist in recycled concrete, and consequently the mechanical strength is poor is solved. The recycled concrete comprises the following components in parts by weight: 200-250 parts of a framework material, 20-40 parts of a gelling filling material, 4-6 parts of a functional additive and 10-30 parts of water, the framework material comprises regenerated aggregate, fly ash, slag powder, gravel or river sand in a mass ratio of 10: 2: 1: 15. The preparation method of the recycled concrete comprises the following steps: removing garbage, retaining waste concrete blocks, crushing the waste concrete blocks, and screening aggregate as recycled aggregate; the method comprises the following steps: sequentially adding the waste coarse aggregate and the filling material into an accommodating tank, uniformly mixing and oscillating, adding the waste fine aggregate, and oscillating for 5-15 minutes. The mechanical property, weather resistance and the like of the recycled concrete are integrally improved, and the service life is prolonged.
本发明公开了一种高聚物环保再生混凝土及其制备方法，涉及混凝土技术领域；为了解决再生混凝土内部存在裂缝，导致力学强度不佳的问题；该再生混凝土，包括以下重量组成分：骨架材料200‑250份、胶凝填补材料20‑40份、功能外加剂4‑6份和水10‑30份；所述骨架材料包括质量比为10:2:1:15的再生集料、粉煤灰、矿渣粉、碎石或河砂。该再生混凝土的制备方法，包括以下步骤：去除垃圾保留废旧混凝土块并将其破碎，筛选骨料为再生集料；先向容罐内依次添加废旧粗骨料和填补料，混合震荡均匀后再加入废旧细骨料震荡5‑15min。本发明使得再生混凝土的力学性能和耐候性等整体提高，延长使用寿命。
