摘要
水泥行业正致力于推动低碳化和超低排放,通过研发新型低碳材料、利用工业固废资源,降低熟料消耗量和污染物排放,以实现绿色可持续发展.采用粉煤灰、水渣矿粉、脱硫石膏及外加剂等组分材料经科学配比、良好的质量控制制备而成的超细复合矿物掺合料,通过部分取代熟料生产低碳水泥,分析超细复合矿物掺合料取代率对水泥性能的影响.结果表明:在三家水泥企业生产的P·O42.5水泥中,掺入20％超细复合矿物掺合料取代水泥熟料,28d抗压强度分别提升4.7％、3.0％和3.6％,28d抗折强度分别提升6.67％、6.0％和7.1％.超细复合矿物掺合料具有取代水泥熟料的良好可行性.
Abstract
In order to achieve green sustainable development,the cement industry is committed to promoting low-carbon and ultra-low emissions,through the development of new low-carbon materials,the use of industrial solid waste resources,reduce clinker consumption and pollutant emissions.The ultra-fine composite mineral admixture prepared by scientific proportioning of fly ash,slag powder,desulfurization gypsum and admixture is used to produce low-carbon cement by partially replacing clinker,and the influence of ultra-fine composite mineral admixture on cement performance is analyzed.The results show that the 28d compressive strengths and 28d flexural strengths of P·O42.5 cement for three companies are obviously improved by adopting 20％ultrafine composite mineral admixture to replace cement clinker in P·O42.5 cement.The ultrafine composite mineral admixture has the good feasibility to repace cement clinker.
