The advanced technologies has led to increases the amount and the type of waste being generated. In this paper Ground-granulated blastfurnace slag (GGBS or GGBFS) was partially replaced with clay into brick for energy consumption. Granulated blast-furnace slag being waste material obtained from iron slag. Clay, lime and (GGBS) were the materials used to manufacture the bricks in this paper. The present involve gives a detailed description on the experimental investigation on the compressive strength and physical properties of the clay with GGBS brick. Totally 6 different ratios of bricks were investigated such as 0%, 5%,10%,15%,20%,25%,30%. From the results it is obtained that 5% of lime was added constantly to increase the stability and also the increment of 5% of GGBS added in various ratios. The obtained energy consumption was very less compared with conventional burnt clay bricks and calcium silicate bricks. Sufficient strength was also obtained by molding the bricks at significantly lower pressure compared with calcium silicate bricks. From the results it was found that using GGBS as the main stabilizing agent in Brick production can reduce the cost of energy in the firing process. © 2020 Elsevier B.V., All rights reserved.
