STUDY OF UTILIZATION OF WASTE GLASS POWDER AS FINE AGGREGATES TO ACHIVE HIGH STRENGTH CONCRETE

Abstract

Waste glass is one materials when ground to a very fine powder shows pozzolanic properties which can be used
as a partial replacement for cement in concrete. In this paper, an attempt has been made to find out the strength
of concrete containing waste glass powder as a partial replacement of cement for concrete. Glass is used in
many forms in day-to-day life. It has limited life span and after use it is either stock piled 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 concrete industry as a
replacement of coarse aggregate, fine aggregate and cement. Its performance as a coarse aggregate replacement
has been found to be non-satisfactory because of strength regression and expansion due to alkali-silica reaction.
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 fine aggregates to assess the pozzolanic activity of fine glass
powder in concrete. A series of tests were conducted to study the effect of 10%, 15%, 20%, 30% replacement
of fine aggregates with waste glass powder. The present study shows that waste glass if used as a fine
aggregates can increase the strength of concrete if used up to some percentage.
