Marble is an extensively used construction material and widely used in buildings, monuments, and sculptures. As per the Indian Mineral yearbook, total resources of all grades of marble have been estimated at 1945 million tons. The marble industry yields a huge quantity of marble slurry during processing at the marble processing plant. This marble slurry when dries, have some serious impact on the environment as well as on the living being. Many studies have reported the performance evaluation of soil-marble dust composite mixes. Although numerous studies have been conducted with randomly distributed fibers, relatively little work has been done on soil-marble dust and glass fiber composite mixes. Because of this, an experimental investigation being undertaken to investigate the performance of the soil-glass fiber-marble dust composite system. In the present investigation, a total of 20 combinations were prepared. The strength characteristics of Kaolinite clay stabilized at various percentages of marble dust and glass fiber is evaluated for curing period of 7, 14, and 28 days using unconfined compressive strength test.
