In this project we have to evaluate the performance of recycled concrete with M-sand and glass powder. concrete is the most widely used man made construction material. Globally, the concrete industry consumes large quantities of natural resources, which are becoming insufficient to meet increasing demands. It is obtained by mixing cement, water and aggregates in required proportions. Cement manufacturing industry is one of the carbon dioxide emitting sources besides deforestation and burning of fossil fuels. recycle waste glass, one of silica-based industrial by-products ,and use it as a cement substitute for sustainable construction. Waste glass powder (WGP) and waste glass sludge (WGS) were manufactured from the waste glass and their feasibility, for use in concrete a partial replacement of cement, was evaluated. 20% of cement (by weight) was replaced with WGP and WGS and the resulting concretes were tested for mechanical properties and durability. Porosity and phase identification studies were also carried out. After 90-day age, the WGS incorporated concrete exhibited the highest compressive strength. Also, it was found that WGS incorporation in concrete led to reduced porosity due to their greater pozzolanic activity owing to the inherent amorphous nature of WGS. Investigations on frost resistance and chloride ions penetrability further showed that these glass wastes are better in improving these properties.

Glass powder, recycled coarse aggregate, compressive strength, durability, flexural.
