Novel high-strength cement-based repairing material for concrete prefabricated part
The invention relates to the field of prefabricated part repairing materials, and specifically relates to a novel high-strength cement-based repairing material for precast concrete components. The repairing material is prepared from the following components in parts by weight: 20 to 40 parts of ordinary Portland cement, 40 to 60 parts of white Portland cement, 20-40 parts of fly ash, 1-2 parts ofa concrete expanding agent, 10-20 parts of titanium dioxide, 50-100 parts of quartz sand, 1-3 parts of a high-performance early-strength early-setting admixture, 5-10 parts of VAE emulsion and 10-20 parts of water, the effect that the color, texture and appearance are consistent with those of a finished product component can be achieved, and the breaking strength, compressive strength and durability are greatly improved.
本发明涉及预制构件修补材料领域，具体是涉及一种新型混凝土预制构件的高强度水泥基修补料，包括以下重量份的组分：普通硅酸盐水泥20‑40份，白色硅酸盐水泥40‑60份，粉煤灰20‑40份，混凝土膨胀剂1‑2份，钛白粉10‑20份，石英砂50‑100份，高性能早强早凝外加剂1‑3份，VAE乳液5‑10份，水10‑20份，可以达到颜色、质感、观感与成品构件一致的效果，而且大大提高了抗折强度、抗压强度以及耐久性能。
