Recycled concrete and preparation process thereof
The invention relates to the technical field of concrete, in particular to recycled concrete and a preparation process thereof. The recycled concrete is prepared from the following components in parts by weight: 400 to 450 parts of concrete waste, 240 to 270 parts of cement, 300 to 380 parts of machine-made sand, 400 to 460 parts of gravel, 10 to 16 parts of cotton nano cellulose, 150 to 200 parts of water and 75 to 90 parts of coal ash, the preparation process of the recycled concrete comprises the following steps: premixing and mixing. The method has the effects of recycling the waste concrete and improving the structural strength of the recycled concrete prepared from the waste concrete.
本申请涉及混凝土技术领域，尤其是涉及一种再生混凝土及其制备工艺。一种再生混凝土包括以下重量份的组分：混凝土废料400‑450份、水泥240‑270份、机制砂300‑380份、碎石400‑460份、棉花纳米纤维素10‑16份、水150‑200份、粉煤灰75‑90份；一种再生混凝土的制备工艺包括以下步骤：预混料、混合。本申请具有回收利用废弃混凝土，提高通过废弃混凝土制得的再生混凝土的结构强度的作用。
