Análisis del mortero de reparación estructural para concreto en un muelle portuario del cantón Guayaquil

Abstract

The degradation of concrete in port docks, especially in aggressive marine environments like Guayaquil, is a recurring issue that significantly affects the durability and functionality of these infrastructures. Factors contributing to this deterioration include seawater exposure, wetting and drying cycles, temperature changes, mechanical stresses, and the presence of aggressive chemical agents. The consequences are severe, including steel reinforcement corrosion, concrete cracking, loss of strength, and surface disintegration, which not only affect the structure’s aesthetics but also compromise its safety and functionality, reducing its lifespan and increasing maintenance costs. This research focuses on the critical challenge of accelerated deterioration in concrete infrastructures exposed to marine environments, with a specific emphasis on Dock 2 of the Guayaquil Port Terminal, a key structure for the region’s economic development. The dock exhibits advanced degradation due to factors such as salinity, climatic cycles, abrupt temperature changes, and chemical compounds affecting the structure. The primary objective of this study is to assess the feasibility and effectiveness of MAXRITE-F structural mortar as a technically and economically sustainable solution for repairing damaged structures and significantly extending their lifespan. Through a combination of laboratory tests and on-site analyses, the research aims to determine the mechanical properties and durability of the mortar under real service conditions, as well as evaluate the long-term performance of the repairs.
