Evaluación de la Adición de Escoria de Alto Horno en una Mezcla de Concreto de Peso Normal

Abstract

Concrete technology in civil engineering has led companies and professionals to investigate the properties of concrete, focusing on optimizing the mix. In this context, the addition of blast furnace slag in normal weight concrete will be evaluated, studying its compressive strength with replacements of 5%, 10%, 15%, and 20% of fine granular material by blast furnace slag. This research seeks to mitigate the consumption of natural resources and the environmental deterioration caused by the excessive production of concrete. Methodologically, it includes the characterization of materials, petrography studies, mix design and compression tests, showing that the addition of slag does not significantly affect the compressive strength, except for a 10% replacement, where the strength increases by 10%. In addition, it was found that concrete density decreases with greater slag participation, affirming the convenience of using this industrial waste as fine aggregate and providing a basis for studying other concrete properties, such as durability.
