Evaluation of physical properties, mechanical properties, and indicators associated with ionic transport in Portland pozzolanic concretes made with rice husk ash: potential applications in Ecuador.

This dataset supports an experimental study on the use of rice husk ash (RHA) as a supplementary cementitious material in Portland pozzolanic concretes produced with Type GU cement, with specific focus on its potential application in Ecuador. It includes mix proportions for concretes with 0, 3, 7, 9, 11, and 14 wt.% RHA replacement, fresh-state properties, and results of compressive strength, electrical resistivity, and effective porosity tests performed at different curing ages. The data were generated following ASTM, INEN, AASHTO and RILEM-based procedures, and allow assessment of how RHA dosage and curing age jointly influence mechanical performance, pore structure–related indicators and ionic transport-related parameters. Overall, the dataset provides a basis to identify technically feasible replacement ranges (particularly 3-7 wt.% RHA) for structural concrete, while contributing local evidence for the valorization of an agro-industrial residue in low-clinker, more sustainable concretes in the Ecuadorian context.
