Abstract

A “touch one bottom” prototype system for estimation of Bingham rheological parameters of SCC has been developed. Video image analysis is used to obtain a series of corresponding values of concrete spread versus time during an automatic slump flow test. The spread versus time curve is subsequently used to estimate the Bingham rheological parameters by a least square search into a database. It takes less than 120 seconds from the start of the slump flow test to the SCC’s Bingham rheological parameters appear on the system’s PC.
