A Study of Cement and Aggregate Replacement in Concrete using Glass Powder and Recycled Aggregate

It has been estimated that several million tons of waste glasses are generated annually worldwide. The key sources of waste glasses are waste containers, window glasses, window screen, medicinal bottles, liquor bottles, tube lights, bulbs, electronic equipments etc. Only a part of this waste glass can be used in recycling. The remaining waste glass cannot be used for any purposes. But recently the research has shown that the waste glass can be effectively used in concrete either as glass aggregate as fine aggregate or as coarse aggregate or as a glass pozzolana. The waste glass when grounded to a very fine powder shows some pozzolanic properties. Therefore the glass powder to some extent can replace the cement and contribute to the strength development.In a growing country like India a huge amount of industrial waste is polluting the environment. With a view of the above, this study aims at utilization of such industrial by product for value added application. In addition the waste can improve the properties of construction materials. The recycled glass has been used in the form of powder. The glass powder was tested with concrete and mortar. Cement was replaced by the glass powder in some proportion. The flexural strength was conducted for the above replacements. The result showed glass powder improves the mechanical properties. The advantages of this project are that the replacement of glass powder is economically cheap as well as a superior concrete can be made.Concrete is the most widely used man made construction material in the world. The popularity of concrete is due to the fact that from the common ingredients the properties of concrete are tailored to meet the demand of any particular application and then most widely used in all types of civil engineering works including infrastructures, low and high rise buildings, defense developments. It is obtained by mixing cementing materials, water and aggregate. However, in recent years the wisdom of own continued wholesale extraction and use of aggregate from natural resources has been questioned at on an international level. This is mainly because of the depletion of quality primary aggregate and greater awareness of environmental protection. In light of this the availability of natural resource for future generations has also been realized. In fact, many governments throughout the world have now introduced various measures aimed at reducing the use of primary aggregates and increasing reuse and recycling where it is technically, economically or environmentally acceptable. The project explores a theme on the need for recycled aggregates and glass powder and highlights its potential use as aggregate and cement in new concrete construction. Research comprises of studies on offer of replacement of cement and aggregate by glass powder and recycled aggregate in concrete by some percentage for 28 days flexural strength of concrete. A result show that the flexural strength of recycled concrete gives higher results with 5 glass powder and 20 recycled aggregate and slightly lower result with 10 glass powder and 20 recycled aggregate and 20 glass powder and 10 recycled aggregate .
