The influence of the interaction among water-cement ratio, content of expansion agent, water reducing agent, and retarder on the compressive strength of new sealing material was studied. The Design-Expert software was used to design experiments, establish a quadratic polynomial regression model, draw response surface, and optimize parameters. The m...

... The optimization process is easier to complete when the RSM approach is used, which leads to a more accurate scientific test. Additionally, it can identify the component(s) that further affect the model or prototype, enabling researchers to concentrate on those components for result compatibility [6,14,15]. [15,16,17] and others have demonstrated the effectiveness of the optimization procedure (s). Chemical therapy of Carica papaya stalk with Zinc Chloride (ZnCl 2 ) resulted in a strongly productive and ecologically friendly adsorbent (globule) in this study. ...
