The objective was to identify the main factors influencing concrete quality, evaluate the use of safety equipment, verify technological control, and analyze the productivity and financial costs of different methods. The research was conducted through interviews with professionals in the field and technical visits to construction sites. The results indicated that concrete produced in mixers is the most used in Santarém, especially for small structures, while ready-mix concrete is preferred for large quantities and heights. The quality of the concrete was affected by factors such as poor aggregate quality, excess water, and lack of technological control. The study concludes that ready-mix concrete is the most recommended due to its productivity and technological control, although there are still challenges to be overcome.ConcretoProduçãoConstrução CivilQualidadeSantarémpdf.Engenharias; Engenharia Civil; Materiais e Processos Construtivos
