Análisis de resistencia a compresión de hormigones con agregados orgánicos y hormigón tradicional para optimización de costos en viviendas de interés social en la Provincia de los Ríos Cantón Babahoyo

Abstract

CONDITION FOR PUBLICATION OF PROJECT. This project analyzes the compressive strength of concrete made with organic aggregates, such as cocoa husk and banana stem fiber, compared to traditional concrete, to optimize costs in low-income housing in the city of Babahoyo, province of Los Ríos, Ecuador. The research is justified by the need to implement sustainable and economic construction solutions for vulnerable communities on the Ecuadorian coast. Materials such as Portland cement, sand and organic aggregates were used for the development of the project, applying mixing techniques and compression tests, according to the Technical Building Standard (NTE), the Ecuadorian Institute for Standardization (INEN) and the American Society for Testing and Materials (ASTM). Resistance tests were carried out at 7, 14 and 28 days, obtaining that the mixtures with banana stem fiber achieved better resistances, with values of 178.1 and 161.9 kg/cm², which represents 84.81% and 77.10%, respectively, of the resistance of traditional concrete, which is 210 kg/cm². These findings indicate that concretes made with banana stem fiber in the proportions of 10% less sand + 10% organic aggregate and without subtracting sand + 10% organic aggregate, are technically viable for the construction of single-story social interest housing, generating a sustainable construction solution that promotes the circular economy and can contribute to the development of social interest projects. This project contributes to the Sustainable Development Goals (SDG), specifically SDG 1 (End of poverty), SDG 11 (Sustainable cities and communities) and SDG 12 (Responsible consumption and production). Keywords: Concrete, organic aggregates, resistance, sustainability, circular economy.
