Superfine mixed sand concrete and preparation method thereof
The invention relates to a concrete material and a preparation method thereof, in particular to superfine mixed sand concrete and a preparation method thereof. The superfine mixed sand concrete comprises cement, fly ash, mineral powder, superfine sand with the fineness modulus of 0.8-1.2, coarse sand with the fineness modulus of 3.1-3.7, pebbles, water, a water reducing agent and a surfactant, and the surfactant is a fluorocarbon surfactant with a branch chain. In the preparation process, the mixing degree of the components is good, construction is convenient, and the prepared concrete has good strength, good weather resistance, good surface smoothness and difficulty in cracking. The fluorocarbon surfactant used in the components is of a short-chain branch chain type.
本发明涉及混凝土材料及其制备方法，特别是涉及到一种特细混合砂混凝土及其制备方法。一种特细混合砂混凝土，包括水泥、粉煤灰、矿粉、细度模数为0.8‑1.2的特细砂、细度模数为3.1‑3.7的粗砂、石子、水、减水剂和表面活性剂，表面活性剂为带枝链的氟碳表面活性剂。制备过程中组分间混合度好，便于施工，制备的混凝土具有良好强度、耐候性好、表面光洁好并且不易开裂。组分中使用的氟碳表面活性剂为短链枝链型。
