Study of Strength and Workability of Different Grades of Concrete by Partial Replacement of Fine Aggregate by Crushed Brick and Recycled Glass Powder

Concrete is the most indisputable and indispensable material being used in infrastructure development throughout the world. Umpteen varieties of concretes were researched in several laboratories and brought to the field to suit the specific needs. Although, natural fine aggregates (i.e. river sand) are so far and/or will be superior to any other material in making concrete but their availability is continuously being depleted due to the intentional overexploitation throughout the globe due to rapid urbanisation and construction of other amenities. Hence, partial replacement of fine aggregate by the other compatible material like sintered fly ash, crushed rock dust, quarry dust, glass powder, recycled concrete dust and others are being researched from the past two decades, in view of conserving the ecological balance. In this direction, an experiment investigation of strength and durability was undertaken to use “Spent Fire Bricks” (SFB) (i.e. waste material from foundry bed and walls; and lining of chimney which is adopted in many industries) and “Glass Powder” for partial replacement of fine aggregate in concrete. This paper recommends that glass powder and brick powder can be used as an alternate construction material to fine aggregate in concrete.
