Improving the Properties of Gypsum By Using Additives

Gypsum Plaster is an important building materials, and because of the availabilty its raw materials. In this research effect various additives on properties plaster was studied , like Polyvinyl Acetate, Furfural, Fumed Silica at different rate addition two types fibers, Carbon Fiber Polypropylene to a volumetric rate. It found that after analysis results use Furfural as additive by 2.5% optimum ratio it improved flexural Strength 3.18%.When using Acetate 2% plaster, value strength 3.44% standards fraction mixture reference. noted for 1%, increases 15.26%. For 0.5% percentage perfect accessory taking into account cost quality which gives increase in Flexural 41.43% .When 1.5%, where 23.67% . When (PVCF), contains Poly vinyl carbon fiber 62.92%. After analyzing all mixtures (PVCF) best one satisfy aim get structural specially gypsum beams.
