Mechanical properties of self-compacting concrete using steel slag and glass powder

Mechanical properties of self-compacting concrete using steel slag and glass powder Concrete is the universally accepted building material for all types of construction and is the most commonly used material after water.

Abstract

Concrete is the universally accepted building material for all types of construction and is the most commonly used material after water. The developments in concrete has led to the evolution of many types of concretes like geo-polymer concrete, self-compacting concrete, fibre reinforced concrete. Self-compacting concrete is a special type of concrete which flows by its own weight and is having variety of application. The uncontrolled and indiscriminate use of concrete depletes natural resources, as the main constituents such as fine and coarse aggregates which are extracted from the natural rocks. Besides, the use of cement contributes to the production of high volume of greenhouse gases resulting in the global warming. These issues posed a big challenge for the present day engineers to look after the possible alternatives to produce eco-friendly concrete. Apart from this, there were numerous industrial wastes like Steel slag, Glass powder, Fly ash, Ground granulated blast furnace slag etc., that are being deposited in the dump yards with no purpose. In the present study, it is aimed to study the fresh and hardened concrete properties by utilising the industrial wastes such as glass powder and steel slag in the self-compacting concrete. The experimentation is carried out on M20 grade concrete, by partially replacing the cement with 20% of glass powder and fine aggregate with varying quantities of steel slag as 25%, 50% and 75%. The obtained results witnessed that the optimum replacement of fine aggregate as 50% in combination with 20% of glass powder yielding in improved workability. The compressive strength, split tensile strength and flexure strength have shown an increase of 20.95%, 17.05% and 24.44% compared to conventional concrete.
