Abstract
La industria de la construcción es una de las más contaminantes en el planeta, razón por la cual es importante que los nuevos materiales tengan un ciclo de vida circular y un bajo impacto en el medio ambiente. Por esta razón, el objetivo de esta investigación se centra en obtener un ladrillo de suelo-cemento con la incorporación de PET que presente características mecánicas similares a los ladrillos cerámicos del mercado. Se utilizó el método experimental, para obtener las propiedades mecánicas de resistencia a la compresión, densidad y absorción, mediante el análisis de tres tipos de dosificaciones denominadas TRAT1, TRAT2, TRAT3 y la dosificación testigo SIN.PET, se sometieron 43 probetas, las cuales se ensayaron a los 7, 14, 21 y 28 días. Los resultados obtenidos demuestran que es posible mejorar las propiedades relativas a la compresión de un ladrillo de suelo-cemento mediante la incorporación de PET al 3%, lo que contribuye a disminuir la contaminación porque este ladrillo no requiere cocción.

The experimental method was used to get the mechanical properties of compression resistance, density, and absorption through the analysis of three types of dosages: TRAT1, TRAT2, TRAT3 and the control dose SIN.PET, 43 test specimens were presented, which were tested at 7, 14, 21 and 28 days. The results demonstrate that it is possible to improve the compression properties of a soil-cement brick by incorporating 3% PET, which reduces contamination because this brick does not require firing.
