Superfine mixed sand concrete and preparation method thereof
The invention provides superfine mixed sand concrete and a preparation method thereof, and belongs to the technical field of concrete preparation. The concrete comprises the following components in parts by weight: 150-180 parts of cement, 30-50 parts of silicon powder, 30-50 parts of fly ash, 100-200 parts of superfine sand with the fineness modulus of 0.8-1.2, 200-300 parts of fine sand with thefineness modulus of 1.6-2.2, 200-300 parts of medium sand with the fineness modulus of 2.3-3.0, 200-300 parts of medium sand with the fineness modulus of 3.1-3.7, 1000-1100 parts of stone, 150-200 parts of water, 60-100 parts of epoxy resin emulsion, 3-10 parts of a water reducing agent and 1-3 parts of a glue reducing agent. The superfine mixed sand concrete has the advantages of being low in cost, capable of preventing the surface of the concrete from sanding, not prone to cracking and convenient to prepare.
本发明提供了一种特细混合砂混凝土及其制备方法，属于混凝土制备技术领域，本发明的特细混合砂混凝土，包括按重量份计的150‑180份水泥、30‑50份硅粉、30‑50份粉煤灰、100‑200份细度模数为0.8‑1.2的特细砂、200‑300份细度模数为1.6‑2.2的细砂、200‑300份细度模数为2.3‑3.0的中砂、200‑300份细度模数为3.1‑3.7的粗砂、1000‑1100份石子、150‑200份水、60‑100份环氧树脂乳液、3‑10份减水剂、1‑3份减胶剂。该特细混合砂混凝土具有成本较低，防止混凝土表面起砂，不易开裂，制备方便的优点。
