ASSESSMENT OF VARIOUS METHODS OF TEST FOR CONCRETE STRENGTH
Various methods of concrete testing, including flexural strength from beam breaks, compressive strength and splitting-tensile strength from cylinders; and penetration resistance from steel probes, were evaluated both under controlled laboratory and partically controlled field conditions. Laboratory results provided good correlation for all methods considered, while the results derived from partially controlled field tests deviated somewhat from confidence bands established on the basis of laboratory data. Penetration-resistance and splitting-tensile tests are recommended as a alternate to beam breaks for concretes with specific constituents for use in determining when forms can be removed from, or loads applied to concrete structures subject to bending stresses. /FHWA/
