Abstract
To generate sustainable mortars, this study investigated the impacts of adding two wastes into portland cement mortar: polyurethane powder waste (PU), and foundry exhaust sand (FES). The tests were carried out utilizing a response surface methodology (RSM) configuration with four different manufacturing variables: sand to cement ratio, coarse sand content (CS), FES, and PU replacing natural sand (NS). Compressive strength, modulus of elasticity, void index, and water absorption (Wa) all had substantial fitting values in the data. Furthermore, the experimental findings show that the adopted model is capable of accurately predicting the outcomes, and an optimized mortar combination was discovered and is presented.
