DEVICE FOR MEASURING VISCOSITY OF CONCRETE MIXTURE Russian patent published in 2020 - IPC G01N11/00 

FIELD: monitoring and measuring equipment.

SUBSTANCE: invention relates to the process of controlling the quality of concrete mixtures, particularly to controlling the rheological properties of the concrete mixture and can be used in construction and research laboratories when measuring the viscosity of a concrete mixture. Essence of invention consists in that device for measuring viscosity of concrete mixture includes metal sole, on which is mounted L-shaped post, in the horizontal part of which there are two blocks of rollers, through which passes the resilient thread with a magnet fixed on it and a counterbalance on the end, on the other end of the elastic thread there fixed is a lead ball, preliminarily immersed into a detachable cylinder, which together with rubber insert is installed on vibration platform with vibrator and fixed by means of fasteners, at that in vertical part there fixed are two magnetically controlled sealed contacts and reading device in form of electronic timer.

EFFECT: technical result is accurate calculation of dynamic viscosity of concrete mixture, which became possible, owing to use in device of magnetically controlled tight contacts and electronic timer, which provides accurate measurement of the path and time of movement of the ball in the cross-section of the column of the concrete mixture and enables to control the rheological properties of the concrete mixture when making reinforced concrete articles and structures.
