Desarrollo de un material compuesto de matriz cementicia con polvo de asfalto reciclado como material cementicio suplementario

Abstract

Abstract: In construction the global release of carbon dioxide for the production of cement reaches alarming levels, that is why sustainable alternatives are sought such as the use of supplemental cementitious materials (SCM), specifically asphalt dust recycled(RAP) for its excellent chemical properties. In this research, in mortar (dosage 1:1.6 a/c 0.6) part of the cement was replaced with sieved RAP in the proportion of 0%, 0.5%, 1%, 2.5%, 5% and 10%, the RAP underwent a size test particle size, X-ray fluorescence assay, X-ray diffraction, granulometry arid, the fresh mortar was tested for fluidity, the hardened mortar was They carried out tests after 28 days, of compressive strength, water absorption by immersion, water absorption by capillarity, open porosity, apparent density. The Results indicate that the mortar with 0.5% RAP increases the resistance, decreases water absorption by immersion, water absorption by capillarity, open porosity and the apparent density is maintained, that is, it is a mortar that does not compromise the mechanical or physical properties.
