One-step formed decorative fair-faced concrete and production process thereof
The invention belongs to the technical field of concrete preparation, and particularly discloses one-time pouring molding decorative fair-faced concrete, which is prepared from the following raw materials in percentage by weight: 13% of cement, 2% of pulverized coal cinder, 2% of blast furnace slag powder and the balance of admixture. According to the invention, the formula of fair-faced concreteis improved; and the concrete is prepared by mixing cement, pulverized coal cinder, blast furnace slag powder which is ground by a cement production line and has the specific surface area of about 400, and an admixture consisting of a water saving agent (polycarboxylic acid), stones with the particle size of 5-25 mm, natural medium sand with the fineness modulus of 2.5 (the particle size is about2 mm), 7% of water, a lubricating agent and a defoaming agent, wherein the laying surface is flat and smooth, and the antifoaming agent enables the compactness of the finished product to be high, so that air holes and pitted surfaces are not easy to generate on the laying surface, putty emulsion paint and other materials are not required to be used for secondary indoor decoration when the concreteis used for indoor wall decoration, the decoration cost is reduced, and the wall surface is not easy to crack and fall off.
本发明属于混凝土制备技术领域，具体公开了一次性浇筑成型装饰清水混凝土，由以下重量百分比的原料配比而成：水泥13%、粉煤渣2%、高炉矿渣粉2%、余量为外加剂；本发明改良了清水混凝土的配方，采用水泥、粉煤渣、由水泥生产线研磨得到的比表面积约400的高炉矿渣粉以及由节水剂（聚羧酸）、粒径为5‑25mm的石子、细度模数2.5（粒径约2mm）的天然中沙、水7%、润滑剂以及消泡剂组成的外加剂混合制成，敷设表面平整光滑，且消泡剂使成品密实度高，从而敷设表面不易产生气孔和麻面，用于室内墙面装修时不需要采用腻子乳胶漆等材料进行二次室内装修，降低装修成本，且墙面不易开裂脱落。
