Glass powder based concrete cubes are cast practically and the strength of the concrete have been investigated and reported in terms of compression. Strength, workability and durability of waste glass powder replaced concrete can be comparable with the normal concrete. The present thesis work is aimed at concrete mix with partial replacement of glass powder by cement (0%, 10%, 20% and 30%) that will reduce the extra burden on the use of cement and also reduce the cost of construction. In this mix design behavior of fresh concrete and hardened concrete evaluated. Key Words: Glass powder, Ordinary Portland cement 43- grade, Concrete, Workability and Compressive strength. 1. INTRODUCTION Disposal and safe collection of waste glass is one of the major problem. In our country glass waste generated from construction and demolition of building and other structure are not properly recycled but dumped in an open area. So, therefore this problem can be reduced by reusing the waste pieces of glass. In this research work glass powder which is produced from waste pieces of glass are used as a partial replacement with ordinary Portland cement of 43-grade in manufacturing of the concrete for M25 grade. Due to the high silica content glass powder shows the pozzolanic behaviour with the replacement on cement when particle size of glass is less than 90 micron. In this experimental investigation, we determine the optimum strength of concrete in hardened state and also workability of concrete using a varying proportion of glass powder with the replacement of cement and also determine the other physical properties of concrete and compare it with conventional concrete properties. 1.1 Objectives 1. To find out its utilization in the construction sector. 2. To relieve the extra burden on cement by replacing it with glass powder made from C & D waste. 3. To find out the comparison of a physical characteristic of cement with waste glass. 4. To detect the behavior of fresh and hardened concrete with waste glass. 1.2 Advantage over normal concrete The normal concrete is vital and economical but the maintenance cost of normal concrete is large on the other hand if the concrete is replaced with glass waste then cost is less and also workability, durability, and strength is very precious as compared to normal concrete. Replacement of glass powder with cement in concrete improves the compressive strength and workability at less to moderate grade and proportions as compared to normal concrete. Glass waste betters the flow ability and durability at all ages of concrete. It gives the lighter section and less permeability at a hardened state. It reduce the extra burden on the use of cement 2. MATERIALS USED FOR EXPERIMENT 2.1 Cement Ordinary Portland Cement of 43 Grade of company name Shree cement, available in the market was used for the experiment. Care has been taken to find that the cement was made in airtight containers from single batching to prevent it from the effect of atmospheric conditions. After that cement was tested and checked for physical properties such as standard consistency, initial and final setting time, fineness and compressive strength according to IS: 8112-2013. Calculated Specific gravity of cement was 3.15 obtained. 2.2 Glass powder Waste glass finds from building demolition and construction was been collected and produced into the powder form. Waste pieces of glass were hard and strong material. These waste pieces of glass create problem in crushing so, therefore pulverize machine was used for making glass powder for a period of 30 to 40 minutes which were resulted in particle size less than 150 microns and sieved over 90 micron. Glass is transparent and made by melting of materials such as soda ash, silica and CaCO3 at higher
