用于三峡二阶段工程中热水泥的技术要求及质量控制

Technical requirement and quality c ontrol for moderate heat cement used in secondary -phase engineering of t he Changjiang gorges

三峡三阶段工程采用525中热硅酸盐水泥在GB200-89基础上制定了技术要求更高的三峡工程水泥质量标准TG-PS03-1998。通过实行业主统一公开招标采购供货制开展质量检测对比竞赛和建立出厂监督、施工自检、监理和业主抽检的多级质量控制体系确保了中热水泥质量为实现三峡高性能水工砼目标奠定了基础。

The secondary -phase engineering of the Changjiang gorges adopted 525mo derate heat Portland cement and set C hangjiang gorges enginee ring cement quality standard TGPS03-1998with higher technical requirement s on the basis of GB200-89.The project carried on unified open tender for purchasing a nd supply,developed quality test co mparison contest and set up o utgoing-plant supervision,self -in-specting of construction,multi -grade q uality control system for construction supervision and pick test of the owner.A ll the measures guaranteed the moderate heat cement quality and provided basis for realizing the aim of high performance hydr aulic engineering concrete in Cha ngjiang gorges.
