The article introduced the quality of moderate heat-of-hardening Portland cement and measures to control each link,for example,controlling the materials and fuels to use in accordance with quality,paying close attention to the reasons to make cement heat of hydration and controlling the cement heat of hydration and harmful component,and controlling the consistency of cement and admixture.
介绍了贵州江电葛洲坝水泥有限责任公司对生产的中热硅酸盐水泥的质量和各个环节进行严格控制的措施:对进厂的原料、燃材料把好质量关,并按材料质量搭配使用;在生产过程控制环节中充分关注影响水泥水化热的原因,并控制好出厂水泥的水化热及有害成分,同时还要控制好水泥与外加剂的相容性。

The expansive mechanism of moderate heat portland cement with slight expansion (MHCSE)in the system of high MgO clinker-gypsum was studied by XRD,SEM/EDAX,strength and expansion measurements.
用XRD ,SEM /EDAX和水泥净浆膨胀测定等方法对高镁中热水泥熟料 -石膏系统的双膨胀中热水泥进行了研究 ,得到 ( 1 )在熟料中明显地存在着相互分散的颗粒尺寸约为 5～ 7。
The results also suggest if the early expansion of ettringite can be used, the retarded expansion of MgO in clinker can be improved, and it will provide basis and means for producing moderate heat portland cement and low h.
利用钙矾石在早期产生膨胀的性能对熟料中氧化镁的延缓性膨胀加以改进，可以为制造微膨胀型中热水泥和低热矿渣水泥提供依据。
