The invention relates to the field of building materials, and particularly discloses waste recycled concrete and a preparation process thereof. The waste recycled concrete is prepared from the following components in parts by weight: 300 to 340 parts of cement, 425 to 460 parts of sand, 900 to 1000 parts of gravel, 460 to 570 parts of a waste material, 15 to 20 parts of an admixture, 85 to 100 parts of expanded and vitrified micro-beads, 30 to 60 parts of EPS particles and 120 to 180 parts of water. The preparation method comprises the following steps: uniformly mixing cement, sand, gravel and a waste material to prepare a premix; and mixing expanded and vitrified micro-beads, EPS particles, an admixture and water, adding the premix, and uniformly mixing to prepare the waste recycled concrete. The waste recycled concrete has the advantages of high porosity, good water permeability and strong freeze-thaw resistance.
本申请涉及建筑材料领域，具体公开了一种废弃物再生利用的混凝土及其制备工艺。废弃物再生利用的混凝土包括以下重量份的组分：水泥300‑340份、砂子425‑460份、碎石900‑1000份、废弃物材料460‑570份、外加剂15‑20份、膨胀玻化微珠85‑100份、EPS颗粒30‑60份、水120‑180份；其制备方法为：将水泥、砂子、碎石、废弃物材料混合均匀，制得预混物；将膨胀玻化微珠、EPS颗粒、外加剂和水混合，加入预混物，混合均匀，制得废弃物再生利用的混凝土。本申请的废弃物再生利用的混凝土具有孔隙率高，透水性好，抗冻融性强的优点。
