High-strength recycled aggregate concrete and preparation method thereof
The invention relates to the technical field of concrete, and particularly discloses high-strength recycled aggregate concrete and a preparation method thereof. The high-strength recycled aggregate concrete comprises the following components in parts by weight: 200-300 parts of cement; 70-120 parts of fly ash; 200-300 parts of water; 5-7 parts of a water reducing agent; 5-7 parts of an air entraining agent; 100-200 parts of a fiber mixture; 300-500 parts of fine stone; 200-300 parts of sand; 400-600 parts of recycled fine aggregate; and 800-100 parts of recycled coarse aggregate. The preparation method comprises the following steps: pre-wetting the recycled aggregate, and mixing the pre-wetted recycled aggregate with sand and stone to obtain a mixture A; adding the fiber mixture and fly ash into the mixture A, and mixing to obtain a mixture B; adding cement, a water reducing agent and an air entraining agent into water, and mixing to obtain a mixture C; and adding the mixture C into the mixture B for mixing. The high-strength recycled aggregate concrete disclosed by the invention can be used for paving a road base, and has the advantages of high strength, good impermeability and the like.
本申请涉及混凝土技术领域，具体公开了一种高强再生骨料混凝土及其制备方法。一种高强再生骨料混凝土包括如下重量份数的组分：水泥200‑300份；粉煤灰70‑120份；水200‑300份；减水剂5‑7份；引气剂5‑7份；纤维混合物100‑200份；细石300‑500份；砂子200‑300份；再生细骨料400‑600份；再生粗骨料800‑100份。其制备方法为：将再生骨料预湿后与砂、石混合得混合物A；将纤维混合物、粉煤灰加入混合物A混合得混合物B；将水泥、减水剂、引气剂加入水中混合得混合物C；将混合物C加入混合物B混合。本申请的高强再生骨料混凝土可用于道路基层铺设，其具有强度高、抗渗性好等优点。
