Feasibility of Study on Effect of Waste Glass Powder as a Partial Replacement of Cement on Compressive Strength of Concrete

The aim of the present work was to use glass powder as a replacement of cement to evaluate the pozzolanic action of fine glass powder in concrete and compare its results of compressive strength with other pozzolanic materials such as silica fume and fly ash. A series of tests were carried out to study the effect of 15% and 20% replacement of cement by, glass powder, fly ash and silica fume on compressive strength and durability in the form of capillary absorption. Many experiments has been done in the concrete industry to use waste glass as partial replacement of fine or coarse aggregates and cement. Glass powder was partially replaced as 5%, 10%, 15% and 20% and tested for its compressive, flexural and Tensile strength up to 28 days of age and were compared to the of conventional concrete, from the results attained, it was found that glass powder can be utilized as cement replacement material up to particle size less than 75µm to avoid alkali silica reaction. Mix of 28 days target strength of 38.25N/mm² using (IS code) was accepted. Initially compressive strength increased till 15% and after it was decreased.
