Polymer composite cement-based grinding stone slurry and production method thereof
The invention relates to polymer composite cement-based grinding stone slurry, which comprises the following raw materials in parts by weight: 10-50% of cement, 3-15% of first-grade fly ash, 30-75% ofgraded aggregate, 1.5-5% of an expanding agent, 0.5-3% of polypropylene fiber, 0.5-3% of rubber powder, 0.13-0.8% of a retarder, 0.1-1% of an accelerant, 0.1-0.6% of a water reducing agent and 0.15-0.8% of a defoaming agent. According to the invention, by compounding the cement disclosed by the invention, various polymers and various additives, large-area subdivision (70 m<2>) can be realized, the shrinkage is less than 0.02%, hollowing and cracking are not easy to occur, the stone jumping phenomenon is avoided, the strength is higher than 30 Mpa, and the scratch resistance is good.
本发明涉及一种聚合物复合水泥基磨石浆料，其特征在于：包括如下重量份数的原料：水泥10～50％、一级粉煤灰3～15％、级配骨料30～75％、膨胀剂1.5‑5％、聚丙烯纤维0.5‑3％、胶粉0.5‑3％、缓凝剂0.13‑0.8％、促进剂0.1‑1％、减水剂0.1‑0.6％、消泡剂0.15‑0.8％，采用本发明的水泥与多种聚合物及多种外加剂进行复配，能够做到大面积分割(70㎡)，收缩小于0.2‰，不易空鼓开裂，无跳石现象，强度高于30Mpa，抗划伤性好。
