Concave-convex wood grain bare concrete construction method, bare concrete and application
The invention relates to the technical field of building materials. The invention discloses a concave-convex wood grain bare concrete construction method, bare concrete and application. S2, formwork engineering; S3, bare concrete engineering; S4, maintenance engineering; and S5, formwork removal protection engineering, wherein a water reducing agent is polycarboxylic acid. The invention also discloses fair-faced concrete which comprises the following components in parts by weight: 74-76 parts of natural sand, 97-99 parts of gravel, 32-35 parts of cement, 4-6 parts of fly ash, 5-7 parts of mineral powder, 0.8-1 part of a water reducing agent, 16-19 parts of water, 1.2-2 parts of a defoaming agent and 0.1-0.3 part of an air entraining agent, the weight ratio of the water reducing agent to the cement is (0.9-1): 35, the weight ratio of the air entraining agent to the cement is (0.11-0.33): 35, and the weight ratio of the defoaming agent to the air entraining agent is (3.6-6): 0.3. The defoaming agent is polysiloxane, and the water reducing agent is polycarboxylic acid. According to the construction method, the proportion of the water reducing agent, the defoaming agent and the air entraining agent is limited, bubbles in the final bare concrete are few, and the bare concrete poured through the construction method is good in appearance, high in performance and simple in process.
本发明涉及建筑材料技术领域。本发明公开了一种凹凸木纹清水混凝土施工方法、清水混凝土及应用。S1：钢筋工程，S2：模板工程，S3：清水混凝土工程，S4：养护工程，S5：拆模保护工程，减水剂为聚羧酸。本发明还公开了一种清水混凝土，其包括：按重量份计：天然砂74‑76、碎石97‑99、水泥32‑35、粉煤灰4‑6、矿粉5‑7、减水剂0.8‑1、水16‑19、消泡剂1.2‑2及引气剂0.1‑0.3，减水剂和水泥之间的重量比为0.9‑1:35，引气剂和水泥之间的重量比为0.11‑0.33:35，消泡剂和引气剂之间的重量比为3.6‑6：0.3，消泡剂为聚硅氧烷，减水剂为聚羧酸。本发明通过限定减水剂、消泡剂及引气剂之间的配比，实现最终清水混凝土中气泡较少，本发明的施工方法浇筑的清水混凝土外观较好，性能较强且流程较为简单。
