High-performance flexible repair mortar
The invention discloses high-performance flexible repair mortar, which is prepared from the following ingredients in parts by weight: 30 to 50 parts of main cementing materials, 15 to 25 parts of auxiliary cementing materials, 80 to 100 parts of river sand, 2 to 5 parts of butadiene styrene rubber, 0.01 to 0.03 part of water reducing agents, 0.05 to 0.1 part of defoaming agents and 0.02 to 0.05 part of retarders. The main cementing material is a mixture of ordinary Portland cement, calcium aluminate cement and gypsum in a mass ratio of (70-80): 15: (8-10); the auxiliary cementing material is a mixture of fly ash, waste perlite powder, granulated blast furnace slag and silicon powder in a mass ratio of 30: (5-10): 10: (10-20). The repair mortar provided by the invention is low in cost and excellent in mechanical property.
本发明公开了一种高性能柔性修补砂浆，以重量份计，包括以下组分：主胶凝材料30‑50份，辅助胶凝材料15‑25份，河砂80‑100份，丁苯橡胶2‑5份，减水剂0.01‑0.03份，消泡剂0.05‑0.1份，缓凝剂0.02‑0.05份，所述主胶凝材料是普通硅酸盐水泥、铝酸钙水泥、石膏以质量比为70‑80：15：8‑10的混合物；所述辅助胶凝材料是粉煤灰、废珍珠岩粉、粒化高炉矿渣、硅粉以质量比为30：5‑10：10：10‑20的混合物。本发明提供的修补砂浆不仅成本低，且力学性能优异。
