The aim of this research was the studying of the efficiency of soil stabilization and the technical quality of bricks manufactured with two types of soil treated with chemical additives. For this purpose a sandy soil and a clayey one were added of Portland cement, lime and sodium silicate being their mechanical characteristics evaluated through both non-destructive and destructive methods. The Portland cement and lime admixture contents were 0; 6 and 10%, and the sodium silicate dosage was 4%. Those two methods were associated in order to describe precisely a quantitative parameter called "anisotropical resistance". The results showed that such a parameter could be used as a good index for brick's technical quality evaluation.
