Abstract:

Reinforced concrete is the most widely used building typology in the world, with steel as its most expensive component. The use of high strength concrete tends to enable the making of slender pieces, its use directly implies the monetary cost of the work, thus generating savings or increasing the cost. The present work aims to show the steel consumption for a dimensioned building using 25 MPa and 50 MPa concrete, as well as to provide results regarding the utilization rates of concrete and steel sections and to draw conclusions about the mechanical tests performed to obtain the strengths. mentioned above. With the mechanical tests satisfactory results were obtained for the concrete consistency indexes measured by the slump test and by the axial compression and tensile compression tests it was possible to demonstrate the expected results. With the use of C50 concrete, a reduction in steel consumption was achieved mainly for the columns, when compared to the design made using C25 concrete.
