ANALYSIS OF TECHNOLOGICAL CONTROL IN THE PRODUCTION OF CONCRETE IN SMALL-SCALE CONSTRUCTION SITES IN THE CITY OF NOVA XAVANTINA-MT

Abstract

The implementation of new construction techniques and choices of innovative materials, driven by the pursuit of efficiency and safety, has been guiding continuous evolution in the construction industry. However, there is a significant decline observed in technological control on small-scale construction sites, especially in the concrete production process. The concrete mix design is vital, as it directly impacts its properties and performance. It involves careful proportions of cement, water, aggregates, and additives to meet the desired characteristics. The water/cement ratio is crucial, influencing strength and durability. Excess water compromises strength, increases the risk of pathologies, and reduces the lifespan, potentially leading to structural collapses. Therefore, the objective of this research was to monitor technological control in the production of concrete on small construction sites in the city of Nova Xavantina, Mato Grosso. Works at different stages of development were identified, permission was obtained from the owners, and data was collected through standardized tests. Additionally, workers were questioned about dosing methodologies. Subsequently, the data were tabulated and subjected to a detailed analysis. Through slump tests and compressive strength tests, it was found that, among the nine evaluated works, only one met the minimum strength requirements established by ABNT NBR 6118:2023. Given this reality, a substantial investment in professional training programs becomes imperative, aiming to address this gap and ensure that construction professionals in Nova Xavantina are adequately equipped to face the technical and regulatory challenges inherent in the industry.
