High-toughness ground wear-resistant cement-based repair material and preparation method thereof
The invention discloses a high-toughness ground wear-resistant cement-based repair material. The repair material comprises the following components in parts by mass: 25-40 parts of cement, 20-30 partsof fly ash, 1-5 parts of silica fume, 30-35 parts of 0.5-2 mm carborundum, synthetic fibers accounting for 1.0%-1.5% of the material use amount, a water reducing agent accounting for 0.05%-0.20% of the material use amount, rubber powder accounting for 0.001%-0.005% of the material use amount, a defoaming agent accounting for 0.03% of the material use amount, a shrinkage reducing agent accountingfor 0.03% of the material use amount and water, which is 0.2-0.3 times greater than the material use amount. wherein the material use amount is the sum of the use amounts of cement, fly ash and silicafume. The high-toughness ground wear-resistant cement-based repair material provided by the invention has the advantages of high strength, high toughness, high crack resistance, high durability and good adhesive property. Besides, a large amount of industrial solid waste is used as a raw material, the requirement for resource regeneration and recycling is met, the production cost is reduced, theenvironment-friendly advantage is achieved, and high social benefits and economic benefits are achieved.
本发明公开了一种高韧性地面耐磨水泥基修补材料，包括25‑40质量份的水泥、20‑30质量份的粉煤灰、1‑5质量份的硅灰、30‑35质量份的0.5‑2mm金刚砂、物料用量1.0%‑1.5%的合成纤维、物料用量0.05%‑0.20%的减水剂、物料用量0.001%‑0.005%的胶粉、物料用量0.03%的消泡剂、物料用量0.03%的减缩剂以及物料用量0.2‑0.3倍的水，以上物料用量指水泥、粉煤灰、硅灰的用量之和。本发明所提出的高韧性地面耐磨水泥基修补材料具有高强度、高韧性、高抗裂性能和高耐久性以及良好的粘结性能。此外，本发明大量利用工业固体废弃物作为原料，符合资源再生循环再利用的要求，即降低生产成本又有环保优势，具有较高的社会效益和经济效益。
