“…To this end, we can use different tests, including the )~2 test, which supplies reliable answers when sample size is large enough, and the Kolmogorof-Smirnov test which can be used on smaller sized samples, as is generally the case in investigations of this sort [7]. Finally it should be noted that in the literature we can also find examples of asymmetrical distributions, other than gaussian distributions [8][9][10], for which it sometimes proves possible to adopt a log-normal distribution model [2,[9][10][11].…”

A B S T R A C T R I~ S U M I~This paper describes a number of statistical methods to estimate, through an analysis of in-place test results, the in-place compressive strength of concrete expressed as strength of standard specimens. The evaluation of the probable existence of a linear correlation as a function of sample size is discussed. The regression laws and the degree of reliability of the estimates obtained is also discussed. A criterion is proposed for the choice of the number of points to be used in the regression. Finally a method is proposed, knowing the number m of replicated in-place tests, to estimate the equivalent number n of replicated tests performed on standard specimens.

A B S T R A C T R I~ S U M I~A method is proposed for the assessment of characteristic cube strength, fck, based on tests performed on 28 mm diameter microcores, small 45 mm diameter cores, and 70 mm diameter cores. In particular, on the basis of the tests performed on the specimens (1270 between cubes and cores of the three diameters being considered, manufactured from 16 concrete types), relationships are defined which make it possible to estimate mean cube strength, Q, with a desired confidence level (1_ -a)~ starting from a mean core strength, f28, f45, f70. Subsequently, given a number ofmicrocores, n28 , n45 , n70 , subjected to compressive tests, the proposed method makes it possible to determine the number of cubes n c necessary to evaluate the mean cube strength with the same confidence level, and characteristic strength with a good approximation. Finally, having worked out the onesided tolerance factor, k, fck is evaluated with the aid of the estimated value of fc, the calculated value of k, and an estimate of the mean standard deviation on cubes, so, as determined from the core tests.
