Fair-faced concrete and preparation method thereof
The invention relates to the technical field of concrete, and particularly discloses fair-faced concrete and a preparation method thereof. The bare concrete is prepared from the following raw materials: cement, fly ash, mineral powder, glass powder, sand, reinforced coarse aggregate, water, a water reducing agent, a defoaming agent and a pumping agent. The preparation method comprises the following steps: (1) adding the cement, the fly ash, the mineral powder, the glass powder, the sand and the reinforced coarse aggregate into a stirrer, and uniformly stirring; and (2) adding the water, the water reducing agent, the defoaming agent and the pumping agent into the stirrer, and continuously stirring uniformly to obtain the fair-faced concrete. The fair-faced concrete disclosed by the invention has the characteristics of high strength and high flowability, so that the step of vibrating is omitted in the construction pouring process, the construction period is greatly shortened, the possibility of misoperation is reduced, and the rework cost is reduced.
本申请涉及混凝土技术领域，具体公开了一种清水混凝土及其制备方法。一种清水混凝土原料包括水泥、粉煤灰、矿粉、玻璃粉、砂子、增强粗骨料、水、减水剂、消泡剂和泵送剂；其制备方法为：（1）将水泥、粉煤灰、矿粉、玻璃粉、砂子和增强粗骨料加入搅拌机中，搅拌均匀；（2）将水、减水剂、消泡剂和泵送剂加入搅拌机中，继续搅拌均匀，得到清水混凝土。本申请的清水混凝土具有具有高强度和高流动性的特点，因此在施工浇筑过程中省略了振捣的步骤，大大缩短了施工周期，降低失误操作的可能性，降低返工成本。
