Viability of Cupola Slag as an Alternative Eco-Binder and Filler in Concrete and Mortars

Obtaining new materials capable of meeting society’s demands motivates the search for solutions that are satisfying twofold requirements: respect environment and obtaining more durable resistant materials. Cupola slag is a by-product generated in process ductile iron. When undergoes rapid cooling, its vitrification favored, leaving silica an amorphous structure and, thus, susceptible to reacting. Through reaction, can develop cementing properties cement consequently be partially replaced with residue, providing savings economic environmental costs compared traditional hydraulic binders. In this study, physical chemical cupola recovery analyzed. Mortars incorporate admixtures (fly ash limestone filler) have been manufactured consistency mechanical mortars admixture. also normalized sand Portland replacements (0, 10, 20, 30% by weight) slag, both at 7, 28, 60, 90 days. The results obtained show suitability as binder admixture, ones, how tend converge all replacement levels characterized, ages close days age.
