【摘要】 本文对开展拌和物流变性能研究在高性能混凝土研究中的重要性和迫切性进行了分析和探讨,在总结研究了国内外现有测试技术和现有实验仪器的基础上,设计了一种结构紧凑,整体性好,体积也不大的新型混凝土流变仪,该仪器既可用于高性能混凝土流变性能研究,又可用于工地实验室的质量控制,还可用于研究拌和物流变性能的经时性变化.更多还原

【Abstract】 The importance and the urgency to study comprehensively the rheological properties of HPC fresh concrete are discussed in the paper. Based on the investigations to the apparatus used up to date, the author puts forward a new design of concrete rheologic apparatus, which is an apparatus with compact design, better integrity and smaller dimensions. The apparatus can be used to study rheological and time-dependent properties of fresh concrete with maximum aggregates 20mm in laboratories, as well as the quality control on construction sites.更多还原
