concrete compression testing machine

YES-2000 digital display compression testing machine

Description
1. Applications
This concrete compressive strength testing machine is to determine compressive strength of cylindrical concrete specimens and cubic concrete specimens by applying a compressive axial load to molded cylinders or cubic at a rate which is within a prescribed range until failure occurs. The compressive strength of the concrete specimen is calculated by dividing the maximum load attained during the test by the cross-sectional area of the specimen.
