COMPREHENSIVE STUDY ON SAND TESTING METHODS FOR QUALITY ASSESSMENT IN FOUNDRY APPLICATIONS

This study looks into improving molding sand preparation in foundries by using data mining techniques to predict moisture content, which is crucial for casting quality. The study uses a number of studies to look into the impacts of fines concentration and void ratios on sand-silt mixtures, with an emphasis on liquefaction resistance, shear strength, and hydraulic conductivity. The interaction of additives with Portland Pozzolana Cement in selfcompacting concrete is researched to determine its impacts on cement composition and admixture performance. Furthermore, bamboo is examined as a sustainable reinforcement alternative in concrete, with performance comparable to steel. The study also investigates the use of 3D sand printing for aluminum casting, showing the benefits in lead time and mold quality. Furthermore, the mechanical and hydraulic properties of concrete mixtures with fibers, tire chips, and fly ash are examined. The statistics show that coarser sands and higher cement content improve the mechanical and bond strength of brickwork, while finer sands have the reverse effect.
