A time-varying detecting device and method for concrete rheological parameters, in which the double-covered cylinder has top and bottom covers (), both of which can be freely opened, is configured to contain a concrete sample, and a lifting frame includes a pair of vertical supports () extending in parallel with each other. The double-covered cylindrical container is held between the pair of vertical supports () by means of connecting members () in such a manner that it can be flipped 180° about a straight line along which the connecting members () extend under the action of an external force. To perform a test, the top cover () is opened and a concrete mix is filled in, followed by detecting initial rheological parameters. The top cover () is closed, and the concrete mix is left for a predetermined period of time. The double-covered cylindrical container is lifted to a predetermined height by raising the connecting members (), flipped 180° and lowered back onto the floor. The bottom cover () is opened, and the concrete mix is re-mixed and homogenized, followed by finally detecting the time-varying rheological parameters of the concrete mix.
