Medeiros Ingeniería concrete Durability absorption resistivity compressive strength This research confronts the following concrete properties: water absorptions (by immersion and capillarity), electrical resistivity and compressive strength. Concrete mixtures with two types of cement were tested. Results showed that concretes with higher content of pozzolan had higher resistivity and greater absorption by capillarity, for water/cement ratios lower than 0,60. This behavior is attributed to reduced pore diameters and microstructure densification. However, for water/cement ratio of 0,60, concrete with lower content of pozzolan presented higher absorption by capillarity. It was observed that the compressive strength and the electrical resistivity behaved inversely proportional to the water/cement ratio, and the absorption by immersion and capillarity are directly proportional to the water/cement ratio. Correlations with high determination coefficients were found between tests. 2019 artículo científico 2007-6835 https://www.redalyc.org/articulo.oa?id=427657986009 https://www.redalyc.org/journal/4276/427657986009/ https://www.redalyc.org/journal/4276/427657986009/html/ https://www.redalyc.org/journal/4276/427657986009/427657986009.epub https://www.redalyc.org/journal/4276/427657986009/movil https://doi.org/10.21041/ra.v9i2.335 en http://www.redalyc.org/revista.oa?id=4276 Revista de la Asociación Latinoamericana de Control de Calidad, Patología y Recuperación de la Construcción application/pdf Asociación Latinoamericana de Control de Calidad, Patología y Recuperación de la Construcción, A.
