Evaluación de la sustitución parcial del cemento por las cenizas de la tusa de maíz.

Abstract

Abstract:The high consumption of natural, energy resources,and the emissions of CO2 and other pollutants compromise the future use of supplementary cementitious materials within construction (Águila and Sosa 2008)In this title work, chapter one, the historical antecedents of cementing materials before and after Christ are summarized, until the evolution of our days, the changes that this material has undergone throughout the time of its evolution, pros and cons that this has repercussions, then the problem of pollution by greenhouse gases, carbon dioxide CO2, is discussed. In chapter two the study of some references is presented, focusing especially on agro-industrial ashes that are added to cement mixtures, becoming an environmentally friendly pozzolana, an example of which we have RHA (rice husk ash), BA (ash from sugarcane bagasse), and CCA (cob ash or corncob) among many others.The development includes the personal study of the obtaining and use of corn cob ash, the process of obtainingthe raw material, burning in the open air, activation, grinding and screening, the analysis of X-ray fluorescence, and diffraction of X-rays, culminating in a pH measurement study, being clear which of the three subjects studied gives us the best securitywhen obtaining and using them.
