Preparation method of low-carbon spheroidized road Portland cement and cement thereof
The invention provides a preparation method of low-carbon spheroidized road Portland cement and cement thereof, and the preparation method comprises the following steps: pre-grinding road Portland cement clinker, gypsum and an active mixed material, and then grinding and shaping through a vertical grinding machine, or directly feeding the active mixed material into the vertical grinding machine; the road Portland cement clinker and the gypsum are subjected to pre-grinding treatment and then enter a vertical grinding machine to be ground and shaped together with the active mixed material; the invention further provides the low-carbon spheroidized road Portland cement, after grinding and shaping through the preparation method, the residue on sieve of a 45-micron square hole sieve is 5-20%, the uniformity coefficient is 0.89-1.00, the average circularity is 0.76-0.87, and the average length-diameter ratio is 1.33-1.57. The low-carbon spheroidized road Portland cement and the preparation method thereof can realize high-efficiency and low-carbon production, are used for concrete, and can improve the workability of the concrete, improve the freezing resistance and wear resistance of the concrete and prolong the service life of the concrete.
本发明提供一种低碳球形化道路硅酸盐水泥的制备方法及其水泥，所述制备方法包括：所述道路硅酸盐水泥熟料、石膏以及活性混合材料采用预粉磨处理后通过立式研磨机研磨整形，或者所述活性混合材料直接进入立式研磨机，所述道路硅酸盐水泥熟料、石膏通过预粉磨处理后进入立式研磨机与活性混合材料一并研磨整形；本发明还提供一种低碳球形化道路硅酸盐水泥，通过制备方法研磨整形后45μm方孔筛筛余5‑20％，均匀性系数0.89‑1.00，平均圆形度0.76‑0.87，平均长径比1.33‑1.57。本发明低碳球形化道路硅酸盐水泥及其制备方法可实现高效、低碳化生产，用于混凝土，可改善混凝土工作性，提高混凝土抗冻性和耐磨性，延长混凝土使用寿命。
