随着高性能混凝土技术的快速发展,各种高品质矿物掺合料的研究使用也是日新月异,需求量不断增加。但高品质掺合料相对较少,绝大部分掺合料还是低品质的,因此低品质掺合料也逐渐受到重视。对产量较大的低品质粉煤灰、粒化高炉矿渣做了简要介绍,分析了相关的技术路线和作用形式效果,为低品质矿物掺合料在高性能混凝土中的应用提供借鉴。 With the rapid development of high-performance concrete technology, the research use of various high-quality mineral admixtures is also changing rapidly with increasing demand. However, relatively low-quality high-quality admixture, the vast majority of admixtures or low-quality, low-quality admixtures have also gradually been taken seriously. The production of low quality fly ash and granulated blast furnace slag with large output is briefly introduced. The relevant technical routes and effect forms and effects are analyzed, which can provide reference for the application of low quality mineral admixtures in high performance concrete.
