The study aims to characterize the soil of Santarém municipality using the Standard Penetration Test (SPT), dividing the area into 8 zones for geotechnical analysis. Soil type, profile, geotechnical characteristics, and penetration resistance (Nspt) were evaluated, highlighting significant variations in nearby areas and the influence of the water table.
The study compared the production of concrete in batching plants and on-site in Santarém-PA, identifying the most used methods and the factors affecting material quality. Technical visits and interviews with professionals highlighted the prevalence of mixer use, lack of technological control, and poor aggregate quality as main challenges.
