Concrete polymer inorganic composite repairing agent
The invention belongs to the technical field of concrete repairing, and particularly discloses a high-molecular inorganic composite repairing agent for concrete. Comprising the following components in parts by mass: 400-500 parts of a cement-based material, 20-30 parts of CPE (Chlorinated Polyethylene), 450-550 parts of quartz sand, 15-30 parts of EVA (Ethylene Vinyl Acetate), 2-5 parts of a polycarboxylic acid high-performance water reducing agent, 20-30 parts of gypsum, 2-3 parts of a defoaming agent, 1-1.5 parts of PP (Polypropylene) fibers, 1-3 parts of an anti-aging agent, 5-10 parts of a thickening agent and 1-2.5 parts of a high-molecular polymer, the high-molecular inorganic composite repairing agent provided by the invention has the characteristics of good workability, short setting time, high early strength which can reach 20 Mpa or above within 2 hours, high strength which can reach 60 Mpa or above within 28 days, strong bonding force, high crack resistance, high pressure resistance, high shear resistance, weather resistance, good durability, easiness in plasticity and micro-expansion function; according to the method, sleeper defect (including cracks, corner chipping, damage and the like) parts, open joints between pipelines and ballast bed layers and ballast bed transverse crack parts at positions corresponding to pipe piece joints can be rapidly repaired, so that the quality requirements are met, and the service life of the sleeper is effectively prolonged.
本发明属于混凝土修复技术领域，具体公开了混凝土高分子无机复合修复剂，包括如下质量份的组分：400‑500份水泥基材料、20‑30份的CPE、450‑550份的石英砂、15‑30份的EVA、2‑5份的聚羧酸高性能减水剂、20‑30份的生石膏、2‑3份的消泡剂、1‑1.5份的PP纤维、1‑3份的防老剂、5‑10份的增稠剂以及1‑2.5份的高分子聚合物；本发明提出的高分子无机复合修复剂具有和易性好、凝结时间快、早期强度高2小时可达20Mpa以上、28天强度可达60Mpa以上、粘接力强、抗裂、抗压能力强、抗剪切能力强、耐候、耐久性好、易塑性、具有微膨胀功能的特点，能够快速对轨枕缺陷(包括裂纹、崩角和破损等)部位、管道与道床层间离缝以及管片接缝对应位置道床横向裂缝部位进行修复，使其满足质量要求，有效延长其使用寿命。
