Study on the Rheological Behavior of Taiwan Concrete
A medium strength high performance concrete (HPC) is named as TAICON in this article. In general the HPC should have not only fluid consistency but also uniformity and limited segregation hazard. Currently, the consistency of HPC is mainly represented by the slump test as well as the other test methods, which is not sufficient for characterizing the rheological behavior of HPC. On the other hand, it has been well affirmed that the consistency of fresh concrete can be interpreted by the theory of rheology. For developing a new method to measure the fluidity of HPC it will be based on its rheological behavior. In this study the rheological behavior of the TAICON will be firstly investigated and then to develop an appropriate test method for the workability.
Test result shows that appropriate mixture proportions of TAICON are possible to be developed by means of the rheological measurement. This test method can well derived the rheological behavior of fresh TAICON and interprete its consistency. In other word, fresh TAICON confirms to Bingham model and thus the two constants τ0 (yield stress) and μ(plastic viscosity) together characterizes its flow behavior are compatible than single value of the slump-flow test.
