Cement-based self-leveling material and preparation method thereof
The invention discloses a cement-based self-leveling material, which is prepared from the following substances in parts by mass: 25 to 45 parts of ordinary portland cement, 10 to 20 parts of sulphoaluminate cement, 3 to 7 parts of anhydrite, 5 to 10 parts of a filler, 35 to 45 parts of quartz sand, 1 to 2 parts of rubber powder, 0.2 to 0.3 part of a water reducing agent, 0.1 to 0.2 part of a defoaming agent, 0.05 to 0.1 part of cellulose ether, 0.05 to 0.2 part of lithium carbonate and 23 to 27 parts of water. The invention further discloses a preparation method of the cement-based self-leveling material. The preparation method comprises the following steps: S1, preparing the powder part: adding the ordinary portland cement, the sulphoaluminate cement, the anhydrite, the quartz sand, the filler, the rubber powder, the water reducing agent, the defoaming agent, the cellulose ether and the lithium carbonate into a powder stirrer according to the formula ratio, and uniformly stirring. The cement-based self-leveling material is good in fluidity and high in bonding strength, the breaking strength and the compressive strength are greatly higher than those of similar products in the market, and the preparation method of the cement-based self-leveling material is simple and easy to implement and has great application prospects.
本发明公开了一种水泥基自流平，包括以下质量份的各物质：普硅水泥：25‑45、硫铝酸盐水泥：10‑20、无水石膏：3‑7、填料：5‑10、石英砂：35‑45、胶粉：1‑2、减水剂：0.2‑0.3、消泡剂：0.1‑0.2、纤维素醚：0.05‑0.1、碳酸锂：0.05‑0.2、水：23‑27；本发明还公开了一种水泥基自流平的制备方法，包括以下步骤：S1，粉体部分制备：将普硅水泥、硫铝酸盐水泥、无水石膏、石英砂、填料、胶粉、减水剂、消泡剂、纤维素醚和碳酸锂按配方量加入粉料搅拌机中搅拌均匀。本发明的水泥基自流平的流动性好、粘接强度高，抗折强度，抗压强度大大高于市场同类产品，本发明水泥基自流平的制备方法简单易行，具有很大的应用前景。
