The non-standardization of rammed earth construction involves the quality control of such a technique to be so troublesome that it is generally avoided. As a possible approach to improve the mentioned quality control, this paper deals with a series of univariate and multivariate statistical analyses concerning the correlation between a pair of non-destructive testings (rebound index and ultrasonic pulse velocity)and the compressive strength of a specific composition of rammed earth. Both non-linear (univariate)and linear (multivariate) regression models are established so that the variability of the compressive strength is accurately explained by means of both kind of non-destructive testings.
