Abstract

The recycling and disposal of trash have garnered heightened attention. This report presents the results of testing and examination of beams made of reinforced concrete, including pharmaceutical blister waste particles, as an exchange for sand in the concrete. Recycling pharmaceutical blister trash is often challenging and may require substantial energy expenditure. This research included grinding leftover pharmaceutical blisters and using them as a substitute for sand at replacement scales of 5%, 10%, 15%, 20%, 25%, and 30% by the amount of sand in a cubic meter of concrete. The beams were minimally fortified with steel rebar and engineered to collapse under shear. Test findings indicated that using shredded particles from pharmaceutical blister waste as a sand replacement in concrete leads to a decrease in ultimate failure load by around 7.4%. The stiffness characteristics and failure modes of recycled pharmaceutical waste-reinforced concrete are almost equivalent to conventional beams. The maximum capacity for the load was substantially altered, and the load-deflection response exhibited modest changes due to the incorporation of pharmaceutical waste particles up to 18.8%. Comparing the test results, it revealed that the predictions of moment capacity are precise. The disparity between the moment derived from testing and that derived from computed compressive strength was deemed insignificant. It is determined that a maximum of 25% well-graded pharmaceutical waste may be included safely to manufacture this sort of recycled reinforced concrete beams for structural purposes. Consequently, the study's results advocate for the suggested technique of recycling discarded pharmaceutical blisters in concrete.
