Compressive Strength

Compressive strength is the standard strength parameter of concrete that can be evaluated under site conditions as well. The most common method is to use cylinder cores drilled off the structure. Momber (1998b) was probably the first to suggest to use the way how a cylinder fails during the compression test as a criterion of the material behaviour during hydrodemolition.

Compression Testing

Compression testing is essential, insofar as the compressive strength of an FRP may be very different from its tensile strength. A major difficulty is that the use of flat, straight-sided coupons, while convenient from a practical point of view, may require a reduced gage length if buckling is to be avoided in uniaxial compression, depending on the nature of the specimen.
