Abstract

Scanning Electron Microscope (SEM) observations of using slag resulted in more noticeable microstructure with gaps as the higher percentage of manganese slag incorporated in the modified brick. Therefore, the analysis using SEM emphasizes the optimal proportion is required when integrating slag into the production of bricks. Utilizing proportion up to 20% could present an approach for environmentally friendly brick making while minimizing the negative influence on structural strength. This contributes to reactivity and leads to the formation of C-(A)-S-H and ettringite which finally creates a denser structure. However, the similarities of all of these research are when the slag usage is higher than 20%, the pores is more significant.
