Evaluating the Effects of Waste Glass and Waste Marble on the Flexural Strength of Rcc-Beam and Bond Strength of Concrete

Abstract

The industrial waste has been rapidly increased day by day due to the fast growing population and usage of products, which dumps unscrupulously resulting in environmental pollutions. Therefore, it has been recommended that, the disposal of industrial waste would be greatly reduced if it could be incorporated in concrete production. The basic aim of this study is to investigate the characteristics of concrete by using waste glass as binding material in proportion 10%, 20% and 30% and marble waste as a fine aggregate in proportion 40%, 50% and 60% for 1:1.5:3 concrete with w/c 0.5. Flexure, Split tensile and pull out tests were conducted after 28days curing. From results it has been concluded that, strength was increased up to 20% replacement of glass powder and then decrease gradually while in case of marble, strength was increased up to 50% replacement then decrease gradually. Similarly for both cases slump values were higher than conventional concrete.
