The constant challenge of increasing quality in the manufacture of green building components and the lack of standards for the prediction of tensile strength is becoming a relevant challenge. For this reason, this research is focused on the development of a logarithmic function that relates the compressive and tensile strength of compressed earth bricks (CEB). To this purpose, the study examines the influence of different cement dosages (7%, 15% and 20%), drying days (7, 14, 21 and 28 days) and establishes critical correlations between tensile and compressive strengths. Key results indicate a proportional relationship between strength and cement dosage, with an optimal balance identified for maximum performance. A comparison was made between the proposed dosages, where the optimum was 20% cement at 28 days. In addition, a "significant positive" correlation coefficient of 0.77 is observed...
