The invention discloses a concrete repairing agent. The concrete repairing agent is prepared from the following components in parts by weight: 10-18 parts of Portland cement, 6-12 parts of ultrafine sand, 4-10 parts of a polyurea waterproof coating, 3-8 parts of an SY-K expanded fiber anti-cracking waterproof agent, 0.3 to 5 parts of a carboxylic butadiene-styrene emulsion, 3 to 7 parts of polyether polyol and 2-6 parts of adhesive. The concrete repairing agent disclosed by the invention is high in bonding strength, strong in permeability, relatively small in shrinkage rate and porosity and good in repairing effect.
本发明公开了一种混凝土修补剂，按以下组分重量份配制而成，包括：硅酸盐水泥10‑18份；特细砂6‑12份；聚脲防水涂料4‑10份；SY‑K膨胀纤维抗裂防水剂3‑8份；羧基丁苯乳液0.3‑5份；聚醚多元醇3‑7份；胶粘剂2‑6份。本发明产品粘结强度高、渗透性强、收缩率及孔隙率较小，修补效果良好。
