For example, the concrete grade/strength class C20/25 concrete is expected to have a minimum cylinder crushing strength of 20MPa and the same C20/25 concrete is expected to have a minimum cube crushing strength of 25MPa. Concrete grade/strength class C16/20 with a minimum cylinder strength of 16MPa or a minimum cube strength of 20MPa is the
" The compressive strength of concrete is given in terms of the characteristic compressive strength of 150 mm size cubes tested at 28 days (fck). The characteristic strength is defined as the strength of the concrete below which not more than 5% of the test results are expected to fall."
Crushing strength is defined by the International Fertilizer Development Center as the resistance of granules to deform or fracture under pressure (IFDC, 1986). Crushing strength is especially helpful in gauging handling and storage properties of a granular material and determining the pressure limits applied during bag and bulk storage.
Maximum crushing strength is the maximum stress sustained by a board when pressure is applied parallel to the grain. Impact bending involves dropping a hammer of a given weight upon a board from successively greater heights until complete rupture occurs. The height of the drop that causes failure provides a comparative measure of how well the
