ResumenThis paper analyzes the chemical, physical, morphological, mineralogical and pozzolanic characteristics of several reservoir sludges and assesses their potential for use as 20% additions in blended cement manufacture. The studied sludges exhibit good pozzolanic properties, especially sample 5 which has high SiO2, Al2 O3 and Fe2O3 contents. Blended cements prepared with 20% sludge additions complied with the European standard on compressive strength of one of the standardized cements, above 32.5 MPa at 28 days of curing; except for sample 5, which showed similar compressive strength values to the reference cement and up to 2% higher values at long curing times.
