FERRAMENTA ESTATÍSTICA (ANOVA) NA ANÁLISE DA RESISTÊNCIA À COMPRESSÃO

Abstract

Construction systems demand significant amounts of natural resources, however, these are already beginning to present problems as to their scarcity. The incorporation of renewable resources, such as charcoal waste (RCV), in cementitious composites tends to minimize this problem. The present study had the objective of analyzing the variability of the compressive strength of mortars with partial replacement of the fine sand by RCV and to analyze these results statistically by analysis of variance ANOVA. According to the results of compressive strength and ANOVA, compositions with 20% RCV presented better performance, around 28 MPa. This fact proves that the integrated management of systems in scientific research instigates new technologies that corroborate the demands of the market and the environment, paying attention to the constancy in the quality and reliability of the new products and the minimization of environmental impacts.
