Compression Test on Concrete

The degree of platen restraint on the concrete section depends on the friction developed at the concrete-platen interfaces, and on the distance from the end surfaces of the concrete. As a result, in addition to applied compressive stress, lateral shearing stresses are also effective in the concrete specimen.
