Bubble-stabilized concrete suitable for plateau environment and preparation method thereof
The invention discloses bubble-stabilized concrete suitable for a plateau environment and a preparation method of the bubble-stabilized concrete. The concrete is prepared from the following raw materials: cement, a mineral admixture, a continuous grading coarse aggregate, a fine aggregate, a plateau air entraining agent, a moisture regulator, a viscosity modifier, a water reducing agent and water. The plateau air entraining agent, the moisture regulator, the viscosity modifier and other key components are used for preparing the bubble-stabilized concrete suitable for the plateau environment, the plateau air entraining agent enhances the thickness of a bubble film, the moisture regulator stabilizes the gas-liquid phase equilibrium state in the concrete, the viscosity modifier improves energy needed by bubble breaking, and the bubble breaking effect is improved. Compared with the prior art, the concrete has the advantages of remarkable concrete bubble stability in the plateau environment, low cost, effective improvement of the freezing resistance of the concrete and the like.
本发明公开了一种适用于高原环境的气泡稳定混凝土及其制备方法，该混凝土包含以下原料：水泥、矿物掺合料、连续级配粗骨料、细骨料、高原引气剂、水分调节剂、粘度改性剂、减水剂和水。本发明利用高原引气剂、水分调节剂、粘度改性剂等关键组分制备得到适用于高原环境的气泡稳定混凝土，其中高原引气剂增强气泡薄膜厚度，水分调节剂稳定混凝土内部气液相平衡状态，粘度改性剂提升气泡破裂所需能量，与现有技术相比，本发明具有高原环境下混凝土气泡稳定性显著，成本低，有效提高混凝土抗冻性等优点。
