摘要：Glass is used in many forms in day-to-day life. It has limited life span and after use it is either stockpiled or sent to landfills. Since glass is non-biodegradable, landfills do not provide an environment friendly solution.Hence, there is strong need to utilize waste glasses. Many efforts have been made to use waste glass in concreteindustry as a replacement of coarse aggregate, fine aggregate and cement. Its performance as a coarse aggregatereplacement has been found to be non-satisfactory because of strength regression and expansion due to alkali-silicareaction. The research shows that there is strength loss due to fine aggregate substitution also.The aim of the present work was to use glass powder as a replacement of cement to assess the pozzolanic activity offine glass powder in concrete and Study the Properties of concrete. The present study shows that waste glass, ifground finer than 100μm shows a pozzolanic behavior. It reacts with lime at early stage of hydration forming extraCSH gel thereby forming denser cement matrix. The early consumption of alkalis by glass particles mitigate alkalisilicareaction hence increase durability of concrete.Lathe scarps are the waste materials which are collected from workshops and other steel industries at very minimumcost. They are similar to the steel fiber but they don’t have any regular shape and size. The dimension varies withnature of source that is depends upon the type of industries. Scraps considered in this work are 0.5mm thickness.
