Resumen

This research incorporated the husk of aguaymanto (Physalis peruviana) in proportions of 0.2%, 0.4%, and 0.6%, and the mucilage of prickly pear (Opuntia ficus-indica) at 6%, 8%, and 10% as stabilizers. The soil used was obtained from the San José district in Lambayeque, Peru, following the selection process established by standard E.080. The most notable results were observed when incorporating 0.2% husk and 10% prickly pear. Compressive strength in the adobe bricks was 16.82 kg/cm2, representing an 8.4% improvement compared to the control sample. Additionally, in the adobe stacks, resistance increased by 35.8%. The tensile test also showed a 22.4% improvement, with a strength of 1.04 kg/cm2. Regarding absorption testing, a value of 13.16% was obtained, improving by 14.6%, and the suction test recorded 12.09%, representing a 30.3% improvement over the standard.
