Resumen

The study examined the impact of the dosage of calcareous residues from calcareous fan shells, sugarcane bagasse ash, and soil on the physical and mechanical properties of compacted and stabilized soil blocks. The study included cylindrical specimens to determine the compressive strength, parallelepiped specimens to determine the modulus of rupture, and compacted and stabilized soil blocks to determine the capillary suction index. The stabilizing materials were characterized by XRD and thermal analysis, and these finely ground pozzolanic materials interacted, generating a CSH gel from which acicular crystals were produced that filled the pores, acquiring improved physical and mechanical properties. After 14 days of curing, the A3 dosage with 80% S, 5% RCCA, and 15% CBCA showed better results, with a maximum compressive strength of 2.90 MPa, a modulus of rupture of 0.98 MPa, and a suction index of 0.98 MPa, complying with UNE 41410.
