Resumo: |
Due to the small number of studies about the process of production of the concrete dosed in central, as regards the type of employed mixture, this inquiry looked to contribute to the assessment of quality of concrete produced in mixing plant and metering plant. The principal objective of the work was checking if the form of mixing of the concrete can affect your characteristics in hardened state (compressive strength), for that, there was compared the quality of the concrete produced in metering plant and mixed in truck mixer in relation to the mixing plant. As the sample was taken a work, where they had installed a metering plant and a mixing plant, which together produced 300.000 m³ of concrete with the same materials. Inside the proposed objective, also were quantified statistically the existent types of concrete in the same truck mixer, using as the parameter the compressive strength of concrete produced in the metering plant. In the end, it was possible to conclude that the mixing plant produce a concrete of better quality with a less standard deviation than the metering plant. Was also observed a significant variability inside the truck mixer, which made the division of the concrete possible in five group, with different resistances' |
