河北省东光县水泥厂研制成功免烧碱激发矿渣水泥,填补了我国水泥行业的一项空白。目前已形成了年产4.4万t的生产能力。 该产品一改传统的两磨一烧的落后生产工艺为一次性粉磨。产品用料广泛,不仅能用高炉矿渣作原料,也可用钢渣、铝渣、磷渣等材料,并可解决部分工业废渣的回收利用。另外由于简化了工艺,从而减少了粉尘及环境污染。该产品具有早期强度高、耐磨性能好、抗折强度、抗硫酸盐侵蚀能力强、抗冻性能好、和易性能优良等特点。与普通水泥相比降低成本三分之一。
Dongguang Cement Factory in Hebei Province successfully developed a caustic soda to stimulate slag cement, filling a gap in the cement industry in China. An annual production capacity of 44,000 tons has been formed. This product is a one-time grinding process that changes the traditional two-burn and one-time production process. The products are widely used. Not only can blast furnace slag be used as raw materials, but also steel slag, aluminum slag, phosphorus slag and other materials can be used, and some industrial waste slag can be recycled. In addition, due to the simplification of the process, dust and environmental pollution are reduced. The product has the characteristics of high early strength, good wear resistance, flexural strength, resistance to sulfate attack, good frost resistance, and easy performance. One third of the cost reduction compared to ordinary cement.
