Utilization of Marble Powder with Glass Fiber as Partial Replacement of Cement in Concrete

Concrete is the most important component used in the construction industry. Due to urbanization, the uses of cement in the construction industry get increased rapidly. This necessitated adopting partial replacement of binder with supplementary cementious material viz., fly ash, slag, metakaolin, marble powder etc. In this research work, M20 grade mix of concrete (with water-binder ratio as 0.48) is adopted with marble powder as a partial replacement for cement. Marble waste is a solid waste material generated from the marble processing and can be used as a filler material in cement while preparing concrete. The amount of waste marble powder generated at the site every year is in the range of 250-400 tons. Glass fiber which is fine fiber of glass, light in weight, extremely strong and robust material is added in concrete to enhance the strength of concrete. The weight of the glass fiber added is 6% by the weight of the cement. The series of laboratory tests are to be conducted to study the effect of 5 to 20 % (in step of 5%) replacement of cement by marble powder with and without glass fiber and compared between marble powder with using glass fiber case and marble powder without using glass fiber by and workability, water absorption and compressive strength of concrete to ascertain the maximum percentage of replacement of marble powder with glass fiber.
