Studies On Self Compacting Concrete Made With Crushed Rock Dust And Marble Sludge Powder



Self-Compacting Concrete (SCC) has had a remarkable impact on the concrete construction industry, especially the precast concrete industry. Concrete plays important role in the construction industry worldwide. New technologies have helped to develop new types of construction and alternative materials in the concrete area. As society makes determined moves towards sustainability, construction has a very important role to play within this new agenda, not only because of its economic and social contribution, but also because of its impact on the quality of our lives, our comfort and safety. While the building industry provides 5% to 10% of worldwide employment and generates 5% to 15% of GDP (Gross Domestic Product), the built environment accounts for 40% of energy consumption, 40% of CO2 emissions, 30% of the consumption of natural resources, 30% of waste generation and 20% of water consumption. The future global challenge for the construction industry is clearly to meet the world's growing needs while at the same time limiting the impact of its burdens by drastic improvement of its activities.  The rapid growth in development of construction industry is leading to an increase in utilization of natural resources like river sand due to which there has been a much scarcity of fine aggregate in availability for construction.
