Abstract

The rheological parameters of Fresh SCC were examined through the theory of rheology, the rheological model of Fresh SCC was assumed to be H-B rheological model, the flowing time of Fresh SCC in the simulated L-box through Fluent, later compared with the flowing time of Fresh SCC in the actual L-box, the target function was established according to the least square method, three rheological parameters 0, k and n were optimized performing the pattern search method, and 6 sets of rheological parameters of 0, k and n acquired from the back analysis underwent the V-funnel verification test, which demonstrates the feasibility to back-analyze the H-B model rheological parameters to some extent.
