Abstract - Concrete is a widely used construction material
for building of various civil engineering structures. Concrete will give better durability and also its costs during construction as well as maintenance are very low. But when it comes to the tensile property it is very weak and tends to fail because of its deficiencies such as low tensile strength, low strain at fracture. The weakness of concrete is due to the presence of micro cracks at mortar aggregate interface. The present experimental work has been carried out for M20 mix proportion and the mechanical properties such as compressive strength, flexural, tensile strength, impact strength tested by hybridizing the concrete with RCA and Crushed Glass. Crushed Glass are hybridized and added in the percentages of 10%, 20%, 30% and 40% the results are compared with controlled concrete. RCA (recycle coarse aggregate) having aspect same percentage as comparing to crushed glass. The test results and variations in mechanical properties are discussed. In this experimental investigation we have the dramatically increase in the compressive strength while comparing it with the 0% of concrete specimen. Key Words: RCA, Crushed Glass, Compressive Strength, Split Tensile Strength…
1. INTRODUCTION Concrete is the world‘s second most consumed material after water, and its widespread use is the basis for urban development. In India 27% of the total waste generated is construction and demolition waste (C&DW). Many countries have recycling schemes for C&DW to avoid dumping to landfill, as suitable landfill sites are becoming scarce particularly in heavily populated countries. Aggregate typically processed from demolition waste concrete is termed as Recycled Concrete Aggregate (RCA). Recycling or recovering concrete materials has two main advantages. It conserves the use of natural aggregate and the associated environmental costs of exploitation and transportation, and it preserves the use of landfill for materials which cannot be recycled. Waste glass is a major component of the solid waste stream in many countries. Glass is a transparent material produced by melting a mixture of materials such as silica, soda ash, and CaCO3 (calcium carbonate) at high © 2017, IRJET

temperature followed by cooling during which solidification occurs without crystallization. It is widely used in our lives through manufactured products such as sheet glass, bottles, glassware, and vacuum tubing. The use of recycled glass helps save of energy.
1.1 RCA (Recycled Concrete Aggregate) In India, a huge quantity of construction and demolition wastes is produced every year. India is presently generating construction and demolition waste of 23.75 million tons annually and these figures are likely to double in the next 7 years. . And the continuous use of natural resources for making conventional concrete leads to the reduction in their availability and results in the increase of the cost of the coarse aggregate and fine aggregate. The possible use of recycling demolition waste as coarse aggregate in the construction industry is thus increasing importance. When recycled coarse aggregate is used in structural concrete, the assessment of physical, mechanical and durable characteristics of recycled coarse aggregate is very important. The physical and mechanical properties of concrete with the recycled coarse aggregate (RCA) are to be evaluated to assess its application as structural concrete. Properties of the recycled concrete aggregates depend on the source, quality of the waste material, percentage ratio of components and also on the sievefraction of aggregate.
1.2 Crushed glass
Glass is a transparent material produced by melting a mixture of materials such as silica, soda ash, and CaCO3 at high temperature followed by cooling during which solidification occurs without crystallization. It is widely used in our day today life. It can be found in many forms, including container glass, flat glass such as windows, bulb glass and cathode ray tube glass. The use of glass as aggregates in concrete has a great potential for high quality concrete development. Its shape and size have potential benefit in obtaining a good particle size distribution in glass concrete.
