Preparation method of impervious concrete material for box culvert
The invention discloses a preparation method of an impervious concrete material for a box culvert. The preparation method comprises the following steps: step 1, preparing materials: ensuring that the materials meet engineering requirements after quality detection; step 2, material proportioning: according to the formula proportion, accurately metering various raw materials; step 3, mixing the materials: firstly putting the cement, the fly ash, the anti-seepage material and the calcium oxide into a concrete mixer, and premixing, so that the materials are fully and uniformly mixed; step 4, adding aggregate: gradually adding the coarse aggregate and the fine aggregate into a stirrer, adding a proper amount of water at the same time, stirring, and ensuring that the aggregate and the cement paste are fully mixed in the stirring process so as to form a uniform concrete mixture; the engineering requirements are met; various materials are combined, so that the performance of the concrete or mortar is optimized; the coal ash and the capillary crystalline material improve the impermeability and the durability; and calcium oxide is beneficial for adjusting the hardening process and improving the firmness of the material.
本发明公开了一种箱涵抗渗混凝土材料的制备方法，包括以下步骤：步骤一，准备材料：并经过确保材料经过质量检测后符合工程要求；步骤二，材料配比：按照配方比例，将各种原材料进行精确计量；步骤三，混合材料：将水泥、粉煤灰、防渗材料和氧化钙先放入混凝土搅拌机中，进行预混，使它们充分均匀混合；步骤四，骨料添加：接着，将粗骨料和细骨料逐渐加入搅拌机中，同时加入适量的水，进行搅拌，在搅拌过程中，要确保骨料和水泥浆充分混合，以形成均匀的混凝土混合物；确保其符合工程要求；本发明结合了多种材料，以优化混凝土或砂浆的性能；粉煤灰和渗透结晶材料提高抗渗性和耐久性；氧化钙则有助于调节硬化过程，提高材料的坚固性。
