Concrete slurry and preparation method thereof
The invention relates to the field of concrete, and discloses concrete slurry and a preparation method thereof.The concrete slurry is prepared from 400-470 kg/m < 3 > of Portland cement, 350-560 kg/m < 3 > of coarse aggregate, 320-450 kg/m < 3 > of fine aggregate, 190-210 kg/m < 3 > of an alkali-activated mineral agent, 425-475 kg/m < 3 > of mineral powder, 350-550 kg/m < 3 > of an active fine admixture, 4-5.8 L/m < 3 > of an additive, 30-60 kg/m < 3 > of heat preservation glass beads, 145-245 kg/m < 3 > of steel fibers and 150-205 L/m < 3 > of water. According to the method, raw materials are precisely proportioned, mineral powder and fly ash in specific dosage are adopted to obtain a cementing material under the excitation action of a specific alkali activator containing NaOH and water glass, and then the cementing material is matched with coarse and fine aggregate, an additive, heat preservation glass beads and steel fibers according to a certain proportion, so that the alkali-activated light recycled concrete slurry is obtained through matching. On the basis of reducing the dead weight of the concrete, the concrete slurry also has shorter setting time and ensures good early strength.
本发明涉及混凝土领域，且公开了一种混凝土浆料及其制备方法，混凝土浆料包括以下组分的原料配制而成：硅酸盐水泥：400‑470kg/m3、粗骨料：350‑560kg/m3、细骨料：320‑450kg/m3、碱激发矿剂：190‑210kg/m3、矿粉425‑475kg/m3、活性细掺料：350‑550kg/m3、外加剂：4‑5.8L/m3、保温玻璃珠：30‑60kg/m3、钢纤维：145‑245kg/m3和水：150‑205L/m3，该方法通过精准配比原料，采用特定用量的矿粉与粉煤灰在包含NaOH和水玻璃的特定碱激发剂的激发作用下得到胶凝材料，再与粗细骨料、外加剂、保温玻璃珠和钢纤维以一定比例配合，从而搭配得到碱激发轻质再生混凝土浆料，混凝土浆料在降低混凝土自重的基础上，还具有较快的凝结时间并保证良好的早期强度。
