ABSTRACT:
This invention is a testing device for concrete having a cylindrical housing adapted to be inserted in a preformed or drilled cylindrical hole in the concrete. The lower end of the cylindrical housing has one or more openings equi-distantly spaced. These openings have bearing shoes therein which are forced outwardly against the concrete by eccentric cams or a force rod which bears against the bearing shoes. A measuring device connected to the cams or force rod measures the pressure on the shoes and a distance which they extend into the concrete to measure the modulus of elasticity of the concrete from which the ultimate compressive strength of the concrete and other parameters may be determined. The device may be calibrated to yield the ultimate compressive strength directly.
