由浙江省建材科学研究所和浙江横山铁合金厂共同协作承担的《水淬精炼铬铁渣做水泥混合材》1987年2月26日通过了市级技术鉴定。水淬精炼铬铁渣是铬铁合金电炉还原冶炼所排放经炉前水淬处理而成,具有活性,基本性能类似于水淬高炉矿渣,无毒、无放射性、对水泥性能无害,作为水泥活性混合材其掺量不超过15%,可生产铬铁渣普通硅酸盐水泥, By the Zhejiang Provincial Institute of Building Materials and Zhejiang Yokoyama Ferroalloy Works co-commitment to undertake the “water quenching ferrochrome cement mixture” on February 26, 1987 passed the municipal technical appraisal. Water quenching chrome iron slag is ferro-chromium alloy electric furnace reduction smelting by the furnace water quenching before discharge, with activity, the basic performance similar to water-blast blast furnace slag, non-toxic, non-radioactive, harmless to cement performance, as cement activity Mixture of its content of not more than 15%, ferrochrome slag can produce ordinary Portland cement,
