Characterization of Algerian reservoir sludges for use as active additions in cement: New pozzolans for eco-cement manufacture
Highlights ► Algerian sludges were studied as pozzolans. ► All sludges analyzed show good pozzolanic properties. ► The incorporation of sludges to blended cement decreases strength, except for SLD5. ► These sludges can be used as active additions to elaborate blended cements.
Abstract This 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, Al2O3 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 32.5MPa at 28days 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.
