Microstructure and mechanical properties of ternary mortars with brick powder, glass powder, slag, fly ash, and limestone
The objective of this research is to study the effects produced by ternary binders which combine the addition of waste brick powder with fly ash, limestone, ground granulated blast furnace slag or waste glass powder in the microstructure and mechanical properties of mortars. In these ternary binders, the ordinary Portland cement was partially replaced by 10% of waste brick powder and 10% of another of the abovementioned additions. Mortars prepared with ordinary Portland cement without additions were also prepared. The microstructure was characterized with mercury intrusion porosimetry, electrical resistivity, and thermogravimetric analyses. Ultrasonic pulse velocity, compressive and flexural strengths were also determined. Mortars made using ternary binders with two active additions showed higher pore refinement and higher electrical resistivity at 250 days. Furthermore, their compressive strength and ultrasonic pulse velocity were relatively similar or even higher than that noted for reference specimens. ; This work was supported by the Conselleria de Educación, Investigación, Cultura y Deporte (presently renamed as Conselleria de Innovación, Universidades, Ciencia y Sociedad Digital) de la Generalitat Valenciana, Spain (grant code GV/2019/070) and by the Agencia Nacional de Investigación y Desarrollo de Chile (ANID) (grant number FONDECYT REGULAR 1211135).
