In the present research, a series of experiments had been performed to compare the use of glass powder and steel powder as partial replacement of sand in different proportions. Concrete mixes are modified by 10%, 15% and 20% and 25% of glass powder and steel powder in replacement. The inclusion of glass powder increases the compressive strength up-to certain proportions. It has also been noted that with the increase in the content of glass powder decreases the slump value or workability. It has also been noted that with the increase in the content of supplementary materials decreases the slump value or workability. Comparatively higher early strength gain (7-days) is obtained with steel powder concrete.
