Abstract

The potential of diatomaceous earth as a usable residue from filtration processes is due to its high silicon content and favorable morphology for chemical reactions. Its refined granulometry and amorphous structure indicate high reactivity. Thus, we explored its application as a partial substitute for Portland cement, aiming to obtain a material with mechanical properties, good durability and lower environmental impacts associated with waste disposal and CO2 emissions. We perform compressive strength and water absorption tests on the molded specimens with the established trace, comparing their performance with that of pure Portland cement. The results obtained were used to evaluate the technical feasibility of this approach to the use of waste in the building materials industry.
