Gypsum Addition in Moulding Sand to Manufacture Defect Free Tin Castings
Abstract: Sand molding is a versatile casting process that provides freedom of design with respect to size, shape, and product quality. Plaster casting is similar to sand molding process except that a plaster is substituted instead of sand. Plaster compound is composed of gypsum, which strengthens the mould. Parts made by this process are gears, valves, fittings, tooling, and ornaments. The finished product of plaster casting has a very high surface …

Sustainable Construction: A Case Study of Passive Cooling Using Various Insulation Materials in an Educational Institution
Abstract: This case study is about insulating an education building where steel sheets are used on the rooftop. Steel roof sheets are good conductors of heat and due to which the classrooms below become heated up especially in the summer season from January to May every year. This educational building was constructed in 2014 and the heat build-up is intense and hence the top floor i.e. second floor was mostly unutilised …

Engineering Sustainable Interior Materials: Performance Analysis of PLA Composites Reinforced with Banana Stem Fiber and Spent Coffee Grounds
Abstract: This study presents the development and classification of eco-friendly composite panels reinforced with spent coffee grounds (SCG) and banana stem fibers (BSF) for interior applications. Hybrid composites were fabricated using polylactic acid (PLA) as the matrix with a constant filler loading of 30 wt%, varying BSF:SCG ratios (70:30, 60:40, 50:50). Mechanical testing revealed that the 70:30 composite exhibited the highest tensile strength (42 MPa) and flexural strength (58 MPa), whereas …
