DEVICE FOR DETERMINING THE RHEOLOGICAL PROPERTIES OF CONCRETE MIX Russian patent published in 2022 - IPC E02D1/00 G01N3/40 

FIELD: rheological properties measuring.

SUBSTANCE: invention relates to the field of measuring the rheological properties of heavy and fine-grained concrete mixes, building cement-sand mortars and monitoring their technical condition at the initial stage of hardening (setting) and can be used in construction, for example, at monolithic construction sites for quality control of monolithic concrete works. The device contains a handle with a rod, made in the form of a rod, parallel to the rod with fastening to the upper and lower stops, an elongated impact driver with the possibility of free movement on the rod, in contact with the upper and lower stops, a conical rod indenter mounted on the lower stop, a mandrel with the possibility of free movement along the indenter rod and the impact on the trigger element of the signaling device installed on the lower stop. The handle has a shock counter and a vertical position indicator.

EFFECT: providing the ability to control the stage of "viability" of the mixture directly at the place of concreting, reducing the time of control, increasing the accuracy of measurements, which ultimately ensures the design quality of the monolithic structure of concrete in the structure.
