Prefabricated bare concrete wallboard and manufacturing process
The invention belongs to the technical field of fabricated concrete wallboards, and particularly discloses a prefabricated bare concrete wallboard and a manufacturing process thereof. The prefabricated bare concrete wallboard comprises a bare concrete facing layer and a bare concrete structure layer; the bare concrete facing layer is at least formed by mixing and spraying first cement, a first admixture, fine sand, a water reducing agent, a water-retaining agent, a polymer emulsion, water and pigment; the bare concrete structure layer is formed by pouring self-compacting concrete or large-flow-state ceramsite concrete; the raw materials of the self-compacting concrete comprise second cement, a second admixture, fine aggregate, coarse aggregate, a water reducing agent and water; the high-flow-state ceramsite concrete is prepared from the following raw materials: second cement, a second admixture, coarse aggregate, ceramsite, a water reducing agent and water. The prefabricated wallboard is perfect in surface, seam, line and hole points, high in compressive strength, attractive in appearance and practical.
本发明属于装配式混凝土墙板技术领域，具体公开了一种预制清水混凝土墙板及制作工艺，所述预制清水混凝土墙板包括清水混凝土饰面层和清水混凝土结构层；所述清水混凝土饰面层至少由第一水泥、第一掺合料、精细砂、减水剂、保水剂、聚合物乳液、水和颜料混合后喷涂而成；所述清水混凝土结构层采用自密实混凝土或者大流态陶粒混凝土浇筑而成；所述自密实混凝土的原料包括第二水泥、第二掺合料、细骨料、粗骨料、减水剂和水；所述大流态陶粒混凝土的原料包括第二水泥、第二掺合料、粗骨料、陶粒、减水剂和水。本发明预制墙板在“面、缝、线、孔”四点上均表现完美，抗压强度高，兼具美观性和实用性。
