The invention discloses a concrete compaction reinforcing agent which comprises the following components in parts by mass: 10-20 parts of silica fume, 30-40 parts of fly ash microspheres, 10-15 parts of a polymer film-forming agent, 7-12 parts of a complexing agent, 10-20 parts of calcium carbonate, 1-5 parts of a water reducing agent, 5-12 parts of an expanding agent, 5-10 parts of sodium methylsilanolate and 1-3 parts of a defoaming agent, wherein the expanding agent is a mixture of a magnesium oxide series expanding agent and a sulfate series expanding agent; and the polymer film-forming agent is at least one of an ethylene-vinyl acetate copolymer, a vinyl acetate-vinyl versatate copolymer and an acrylic acid copolymer. The surface and the overall structure of the concrete are more compact, and the strength, the anti-cracking and anti-seepage performance and the durability of the concrete are remarkably improved.
本发明公开了一种混凝土密实增强剂，包括如下质量份的组分：硅灰10‑20份、粉煤灰微珠30‑40份、高分子成膜剂10‑15份、络合剂7‑12份、碳酸钙10‑20份、减水剂1‑5份、膨胀剂5‑12份、甲基硅醇钠5‑10份和消泡剂1‑3份；其中，膨胀剂为氧化镁系列膨胀剂和硫酸盐系列膨胀剂的混合物；高分子成膜剂为乙烯‑醋酸乙烯酯的共聚物、醋酸乙烯‑叔碳酸乙烯共聚物、丙烯酸共聚物中的至少一种。其使得混凝土表面和整体结构更致密，显著提高混凝土的强度、抗裂防渗性能和耐久性。
