as hazardous waste that requires a large place for dumping.
Induction furnace slag and electric arc furnace slag were used
in this study for making bricks. Cement, lime, gypsumandwater
were used along with the crushed dried slag for making the
bricks. Without firing, they were produced only by applying
forming pressure of 1000 psi, 2000 psi and 3000 psi and cured
under water for different time period of 7 days, 14 days and 28
days. Also the slag percentage was varied to 0%, 10%, 25% and
50%. Their compressive strength, water absorption, porosity
and density were measured. The compressive strength of
different compositions showed ten to twelve times higher result
compared to the conventional burnt clay bricks. In comparison,
electric arc furnace slag bricks revealed higher compressive
strengththantheinductionfurnaceslagbricks.Waterabsorption
percentage was also very low compared to conventional clay
bricks. They showed results with high density with low porosity.
Our main purpose in this research was to prevent environment
pollution and utilize a waste product as a recycling element.
