The purpose of this study was to investigate the compressive strength and permeability of polyurethane-containing and non-dyed concrete containing methacrylene and silica. The compressive strength of all designs increased with increasing age of concrete compared to the control. As the percentage of nanosilica increased, this increase was maintained and increased to 2%. We also see a 1% replacement resistance in nanosized designs. However, in the replacement designs of 3% nano silica and 3% nano copper at 90 days of age, resistance to control samples was reduced. The permeability test results show that at 28 days old nano-copper up to 2% and nano-silica up to 3% is a better replacement and performs better by increasing the concrete age to 90 days nano-copper.
