Experimental Investigation on Glass Powder as Partial Replacement of Cement for M - 30 Concrete

Glass is needed in several forms in today’s life. Its life is limited, and after use it is either stored into sharp edged or sent to landfills. As we know glass is non-biodegradable, landfills does not recommend any environment friendly solution. In India as a most developing country, facing shortage of post consumer’s disposal waste site and it’s become very serious problems. Hence, there is strong need to utilize waste glasses. The aim of the present experimental investigation was to use waste glass powder as a replacement of cement to assess the Compressive, Split tensile Strength and Flexural strengthfor M30 grades of cement concrete and durability, pozzolanic activity of fine glass powder in concrete, compare its performance with percentage, size of glass powder and also perform alkalinity test on waste glass powder added concrete.The results found that 15% addition of GLP increase the higher compressive strength and flexural Strength, replacement of cement , for study of size effect of glass powder i.e. Initial strength gain is very less due to addition of glass powder on 7 th days but it is maximum increases on the 28 th days, with addition of glass powder increase the higher compressive strength and flexural Strength. The replacement of glass powder in cement by 7, 14, 21& 28 days of curing and result was found that 39.2 N/mm 2 , 41.33 N/mm2, 45.01 N/mm2, 49.18 N/mm 2 , 5.39 N/mm 2 , and 5.57 N/mm 2 , 5.4 N/mm 2 and 5.67 N/mm 2 respectively ,and also glass powder size less than 90 micron is very effective in enhancement of strength. It is also found that the average pH values 12.59 observed from all the different samples of alkalinity test showed that the samples tested found to be more alkaline nature and hence more resistant towards corrosion. The alkalinity test of GLP performed good results on adding concrete.
