Concrete Testing Lab U Box Apparatus

About Concrete Testing Lab U Box Apparatus

A U Box Apparatus is a specialized testing equipment used to evaluate the filling ability and passing ability of self-compacting concrete (SCC). It measures the height difference of concrete after flowing through a set of reinforcing bars, helping determine the workability and segregation resistance of the mix.

This apparatus is widely used in construction material testing laboratories, research centers, and quality control departments to ensure high-performance concrete standards.
