Concrete preparation mixing device and method thereof

The invention discloses a concrete preparation mixing device and a method thereof. The method comprises the following steps: mixing cement, fly ash, slag powder and silica fume to obtain a cementing material mixture; mixing the fine aggregate and the coarse aggregate to obtain an aggregate mixture; adding the cementing material mixture and the aggregate mixture into a concrete mixer for treatment to obtain a concrete mixture; and pouring the concrete mixture into a template, and performing vibration and maintenance to obtain the concrete. Therefore, the concrete with excellent performance can be obtained. 公开了一种混凝土制备混合装置及其方法。该方法包括：将水泥、粉煤灰、矿渣粉和硅灰进行混合以得到胶凝材料混合物；将细骨料和粗骨料进行混合以得到骨料混合物；将所述胶凝材料混合物和所述骨料混合物加入混凝土搅拌机中进行处理以得到混凝土拌合物；以及，将所述混凝土拌合物浇筑到模板中，并进行振捣和养护以得到混凝土。这样，可以得到一种性能优秀的混凝土。
