Municipal solid waste incineration slag as potential materials in green engineering as partial or total substitutes for conventional cement in future decades

Abstract

In the context of this research to characterize the slags from the incineration of municipal solid waste as potential supplementary cementitious materials, the principle of comparative analysis of the physical, chemical and mechanical potentials of the portland cement . Was chosen, complemented with Fly Ash in some specific cases. The bases of objective study, we had two slags matured and ground during one night with a weight equal to 25% of the weight of the balls in the mill, designated Slag-Mat1n25%, as well as another slag matured with grinding in the same duration of one night and with a weight equal to 50% of the weight of the balls in the mill designated Slag-Mat1n50%, as well as another unmatured slag called Slag-NMatLL. The percentage proportions of the oxides as main elements and a description of the minor constituent elements in the materials were also determined and presented, thus allowing the elaboration of an analytical table demonstrating the nature of the oxide, namely its molar mass, density, melting and boiling point, as well as the nature of its crystalline structure, all in the chemical part. Also, in the main oxide elements, the ternary phase diagram, the silica and alumina modules, as well as the lime saturation factor were analyzed. Also, the potential reactivity to alkalis of the aggregates, as well as the determination of the Electrical Resistivity Objectives and Description: The objectives and purpose of the data described in this work support our intention of a continuous and in-depth study on the characterization of slag as supplementary cementitious materials. The descriptions refer to the authors' data set duly referenced in this work.
