STUDY ON STEEL FIBRE REINFORCED CONCRETE WITH PARTIAL REPLACEMENT OF MARBLE DUST POWDER AS FINE AGGREGATE

Concrete is the most important component used in the construction industry throughout the world, where the fine aggregate is generally natural sand. The use of sand in construction activities results in the excessive mining. Due to excessive mining, natural resources are getting exhausted. Thus, it is becoming inevitable to use alternative material in concrete. Marble is one of the important materials used in the construction industry. Disposal of the marble powder material from the marble industry is one of the environmental problems worldwide today. And also, Ordinary cement concrete possesses very low tensile strength, limited ductility and less resistance to cracking. It has been proved that different type of fibers added in specific percentage to concrete improves the mechanical properties, durability and serviceability of the structure. As compared to other fibers it is now established that one of the important properties of Steel Fiber Reinforced Concrete (SFRC) is its superior resistance to cracking and crack propagation. In this paper Past studies based on the Steel fiber concrete and utilization of Waste marble powder as replacement of fine aggregate in concrete were investigated.
