Seamless self-leveling cement millstone and preparation method therefor
The present invention discloses a seamless self-leveling cement millstone. The seamless self-leveling cement millstone consists of the following raw materials in parts by weight: 15-25 parts of sulphoaluminate cement; 10-20 parts of ordinary portland cement; 5-10 parts of triplesuperphosphate; 4-5 parts of plaster; 1-2 parts of talcum powder; 0.3-0.7 part of cellulose; 0.8-1 part of water-soluble dispersible rubber powder; 0.5-0.8 part of a water reducing agent; 0.8-1.5 parts of a defoaming agent; 35-45 parts of quartz sand; and 25-35 parts of colored sand. The preparation method comprises: weighing, mixing for a first time, mixing for a second time and mixing for a third time. The seamless self-leveling cement millstone disclosed by the present invention is high in compressive and bending strength, low in expansion and contraction rate, not prone to crack, high in surface abrasion resistance, and good in construction leveling performance and quality stability, and the surface of the millstone has natural granite color and the characteristics of blobs; The preparation method for the seamless self-leveling cement millstone has the characteristics of simple and quick operation, convenient preparation, and low cost, and is suitable for industrial mass production.
