Análisis y desarrollo del diseño de mezcla de mortero incorporando bagazo de caña y mucílago de nopal para construcciones sustentable y resistente

Abstract

Construction faces pressure to adopt sustainable practices due to its high environmental impact. According to the International Energy Agency, the construction sector is responsible for approximately 39% of global energy-related carbon dioxide emissions. This research explores the use of sugarcane bagasse and prickly pear mucilage as environmentally friendly additives in mortars. The research seeks to determine if this mixture can be a viable and sustainable alternative for construction.

GENERAL OBJECTIVE

To evaluate the feasibility of incorporating Prickly Pear Mucilage (Binder) and recycled sugarcane bagasse in mortar production for construction applications, contributing to waste minimization and promoting an alternative within the framework of the circular economy.

With the objective clear, there were three specific objectives, and the methodology was divided into six phases: information search, experimental phase, mixture preparation, laboratory testing, results analysis, and reporting of the results.

Thanks to this methodology and the results obtained, the following conclusions were reached:

- A mortar mix with a design strength of 23 MPa was developed, incorporating 3% sugarcane bagasse and 6% cactus mucilage as the main additives. The design was carried out in strict compliance with the guidelines established by the NSR-10 standards.

- On the other hand, while the conventional mortar showed constant and significant strength growth over the days of curing, the mortar with sugarcane bagasse and cactus mucilage showed slower growth and a negligible increase between days 14 and 28. This limits its applicability in projects requiring high structural strength.
