Abstract
Abstract The steel industry generates large amounts of waste foundry sand (WFS) in landfills. Studies on the viability of using this residue as a fine aggregate have been carried out for asphalt mixtures. However, studies are still scarce in relation to their use in concrete. In this sense, the present work analysed the effects of the use of WFS as fine aggregate in Portland cement concrete, in the electrical resistivity and compressive strength. The results showed that the behaviour of the electrical resistivity varies according to the characteristic of the WFS, whereas the compressive strength tends to be smaller.
