EXPERIMENTAL STUDY ON USE OF WASTE GLASS POWDER AS PARTIAL REPLACEMENT TO CEMENT IN CONCRETE

Glass is unstable in the alkaline environment of concrete and could cause deleterious alkali-silica reaction problems. This property has been used to advantage by grinding it into a fine glass powder (GLP) for incorporation into concrete as a pozzolanic material. In this study the cement is partially replaced using glass powder which is rich in silica. Therefore, we have planned to prepare some numbers of cubes, cylinders and beams using conventional concrete and going to test them for its strength and other properties then we are going to prepare concrete specimens using glass powder at various proportions like 5, 10 and 15%. The casted specimens are tested for its strength. From the test results, we are going to compare the behavior of glass powder concrete with conventional concrete. In this work we are going to use waste glasses, so the cost will be comparatively low when compared with normal concrete.
