Recycled concrete and preparation method thereof
The invention belongs to the technical field of concrete, and particularly relates to recycled concrete which is prepared from, by weight, 40-50 parts of cement, 1-5 parts of water, 140-200 parts of recycled aggregate, 3-5 parts of glass fiber reinforced plastic, 1-3 parts of water reducing agent, 15-20 parts of natural aggregate and 50-65 parts of gel material.The preparation method of the recycled concrete comprises the steps that 1, waste concrete blocks are smashed; 2, stirring the coarse material, the fine material, the natural aggregate and the glass fiber reinforced plastic to form a dry mixture; 3, cement, water and a water reducing agent are mixed to form a wet mixture; 4, pouring the wet mixture into the dry mixture, and uniformly stirring; 5, the gel material is added into the raw materials stirred in the step 4, final stirring is conducted till stirring is completed, the produced recycled concrete has enough tensile strength, and the working efficiency of the device for producing the concrete is higher.
本发明属于混凝土技术领域，具体为一种再生混凝土，包括以下重量份原料：水泥40‑50份、水1‑5份、再生集料140‑200份、玻璃钢3‑5份、减水剂1‑3份、天然骨料15‑20份、凝胶材料50‑65份，一种再生混凝土的制备方法，步骤一，粉碎废弃混凝土块；步骤二，将粗料、细料、天然骨料和玻璃钢进行搅拌形成干混合料；步骤三，将水泥、水、减水剂混合形成湿混合料；步骤四，将湿混合料倒入到干混合料中，进行均匀搅拌；步骤五，将凝胶材料加入到步骤四搅拌完毕的原料中，进行最后的搅拌，直至搅拌完毕，生产出来的再生混凝土具有足够抗拉强度，且生产此混凝土的装置工作效率更高。
