It is not the measurement of workability, slump test has certain limitation, and the mix big for mobility or other media come
It says, is just not suitable for this test method.With construction environment diversification, the relevant technologies are also constantly goed deep into subdivision field
Research, currently, starting gradually deeply to the research of Cracking of High Flowing Concrete, fresh concrete, there are also the mobility of brand-new material
It can study, the domestic parameter that corresponding fluids are measured there is no a suitable equipment, for this purpose, it is proposed that a kind of coagulation soil flow
Become instrument.
Summary of the invention
The main purpose of the present invention is to provide a kind of concrete rheometers, can effectively solve asking in background technique
Topic.
To achieve the above object, the technical scheme adopted by the invention is as follows:
