Comparison of Methods for Estimation of Concrete Strength
Original language description
Statistical procedures for estimating concrete strength from small samples provided in the new European document EN 13791 (2007) are different from those accepted in the material independent Eurocode EN 1990 (2002). Differences are not negligible and appear to be important particularly for assessment of existing structures. The characteristic values (5% fractiles) of concrete strength determined in accordance with EN 13791 are systematically greater than values obtained using the EN 1990 procedure. Thedifferences increase up to 8 MPa with decreasing number of tests. Moreover, according to EN 13791 the variation of the characteristic strength with a number of tests results is discontinuous. Thus, it is desirable to harmonize the procedures given in EN13791 for determining compressive concrete strength with those provided for any material in EN 1990. It is also shown that estimates of the characteristic strength may be improved using prior information.
