Concrete hardened floor structure and construction method thereof
The invention discloses a concrete hardened floor structure and a construction method thereof, and the concrete hardened floor structure comprises a cast-in-place concrete floor slab which is coated with a cement paste layer; the first modified styrene-butadiene emulsion is sprayed on the cement paste layer to form a thin paste sealing layer, and the first modified styrene-butadiene emulsion is composed of a calcium sulphoaluminate expanding agent, styrene-butadiene emulsion, fine sand, cement and water; the concrete surface layer is poured on the thin slurry sealing layer; the second modified styrene-butadiene emulsion is sprayed on the concrete surface layer to form a flexible protection layer, and the second modified styrene-butadiene emulsion is composed of a calcium sulphoaluminate expanding agent, styrene-butadiene emulsion and water. According to the invention, the problem that the concrete floor is still cracked due to the fact that shrinkage of mortar cannot be compensated well when the concrete floor is treated by adopting styrene-butadiene emulsion is solved.
本发明公开了一种混凝土硬化楼面结构及其施工方法，包括：现浇混凝土楼板，所述现浇混凝土楼板上涂覆有水泥浆层；第一改性丁苯乳液，喷涂于所述水泥浆层上以形成稀浆封闭层，所述第一改性丁苯乳液由硫铝酸钙膨胀剂、丁苯乳液、细砂、水泥和水组成；混凝土面层，浇筑于所述稀浆封闭层；第二改性丁苯乳液，喷涂于所述混凝土面层上以形成柔性保护层，所述第二改性丁苯乳液由硫铝酸钙膨胀剂、丁苯乳液和水组成。本发明解决了采用丁苯乳液处理混凝土楼面无法较佳地补偿砂浆的收缩，进而混凝土楼面仍会形成开裂的问题。
