The invention discloses an anti-cracking preservative for enhancing concrete, which is prepared from the following ingredients in parts by weight: 7 to 8 parts of tannic acid modified cerium doped montmorillonite, 5 to 6 parts of modified steel fiber, 3 to 6 parts of modified polypropylene fiber, 8 to 12 parts of superfine mineral powder, 10 to 20 parts of calcium hydroxide and 3 to 5 parts of air entraining agents. The modified steel fiber is prepared by coating the surface of steel fiber with a carbon nanotube/silicon dioxide gel coating; the modified polypropylene fiber is prepared by coating the surface of polypropylene fiber with polydimethylsiloxane/silicon dioxide. The anti-cracking preservative provided by the invention is good in stability, and can effectively improve the strength of concrete and improve the anti-cracking and anti-corrosion performance of the concrete.
本发明公开了一种用于增强混凝土的抗裂防腐剂，以重量份计，包括以下组分：单宁酸改性铈掺杂蒙脱土7‑8份，改性刚纤维5‑6份，改性聚丙烯纤维3‑6份，超细矿粉8‑12份，氢氧化钙10‑20份，引气剂3‑5份；所述改性钢纤维是在刚纤维表面涂覆碳纳米管/二氧化硅凝胶涂层制得；所述改性聚丙烯纤维是在聚丙烯纤维表面涂覆聚二甲基硅氧烷/二氧化硅制得。本发明提供的抗裂防腐剂稳定性好，可有效改善混凝土的强度，提高混凝土的抗裂防腐性能。
