Diseño de vivienda en Samborondón con hormigón estructural que incorpora agregado de concreto reciclado

Abstract

CONDITION FOR PUBLICATION OF PROJECT. The construction industry has expanded over time, and with it has increased the consumption of resources needed to carry out this activity. One of the most exploited resources is the aggregate used in concrete. The Samborondón canton has experienced rapid urban growth, but this increase has led to an increase in demolition waste. New technologies have been developed that replace part of the aggregate with concrete from demolitions. Therefore, the project consists of the design of a two-story single-family home located in the Samborondón canton, using recycled aggregate concrete (RCA) to promote sustainability in construction. Tests were conducted with replacement percentages of 10%, 20%, and 30% to determine the optimal proportion that met structural and economic requirements. The design was developed following international standards ACI 318-19 and NEC 2015. It was found that a 20% recycled aggregate replacement offers the best balance between strength, workability, and cost. In this way, a safe structural design with an environmental focus was achieved, demonstrating the technical and economic viability of using recycled materials in residential construction projects.
