Abstract

Objective: This paper aims to present a methodological proposal for estimating epoxy resin consumption in the repair of cracks in concrete silos, using digital inspection technologies.

Methodology: The study was developed based on a case applied to a concrete silo located in the Northeast region of Brazil. Aerial inspections were conducted using unmanned aerial vehicles (UAVs), followed by photogrammetric image processing, digital vectorization of cracks, and volumetric calculations. These were complemented by descriptive statistical analysis to estimate material consumption.

Originality/Relevance: The research expands traditional approaches to concrete damage assessment, which typically focus on crack detection, by proposing a methodological protocol for the quantitative estimation of resin consumption. It incorporates digital tools and volumetric measurement principles.

Main results: The results showed that the estimated resin consumption ranged from 1,209.69 kg to 1,436.08 kg, while the actual field consumption was 1,350 kg, a value consistent with the confidence interval.

Theoretical/methodological contributions: The study consolidates a replicable model that integrates digital inspection, volumetric calculation, and statistical analysis, contributing to the literature on structural engineering and applied methodologies.

Social/management contributions: The study provides support for supply planning, waste reduction, and increased safety in industrial maintenance operations.
