EValuation of physico-chemical properties when adding boiler ashes to mortar

Abstract

Over the past few years, environmental concern is on focus, it is the case of the continuous reuse of residues from several areas. This work aimed to reuse ashes from a boiler, which temperature reaches 600°C, from a textile factory fueled by wood splinter. It is notorious the amount of generated residue, around 15 tons a month. The material was chemically analyzed with high contents of CaO, this element is ordinarily found in the main binders used in this research. In order to reuse the residue in the mortar mix, several experiments were made, such as SEM, EDX, XRD, pozzolan content, bending and compression trials, adherence and consistency, to characterize the material. The samples analyzed showed progress regarding resistance characteristics, revealing that the residue can be a viable alternative when it comes to contributing to the reduction of Environmental Issues in textile industries.
