摘要
把新拌混凝土看作一种复杂的流体并建立工作性能与流变参数之间的相关性是混凝土优化设计的新思路。阐述了混凝土流变学理论,总结了流变参数与传统工作性能测试方法的特点,结合新拌混凝土工作性能与流变参数相关性研究现状,指出了混凝土工作性能与流变参数相关性研究存在的问题及发展趋势。
Taking fresh concrete as a kind of complex fluid and established the correlation between workability and rheological parameters has developed a new idea to optimize mix design.Rheology theory of fresh concrete has been introduced.The characteristics of different measuring and testing techniques of fresh concrete rheological parameters and workability were summarized.Combined with the state of correlation between fresh concrete workability and rheological parameters research,a review of the existing problems and progress of the research on the correlation between fresh concrete workability and rheological parameters is given below.
