Abstract
This study investigates the combined use of waste glass powder and nano titanium dioxide (TiO2) on the mechanical and durability properties of the concrete. Waste glass being one of the major municipal wastes going into the landfill sites can be used as a pozzolanic material in the concrete, in this study cement is replaced with waste glass powder by 10% along with nano TiO2, it is used as an addition to cementitious material by 0.5%, 1% and 1.5%. Fresh and mechanical properties like setting time, workability, compressive strength and flexural strength is evaluated along with durability properties such as sorptivity, acid, sulphate and chloride attacks, elevated temperature test. Scanning electron microscope is done to understand the morphology of the blended concrete. Combined use of glass powder and nano TiO2 is found beneficial in mechanical and durability parameters whereas addition of nano TiO2 has resulted in decreased workability of the concrete.
