بيت /investigations on optimum possibility of replacing cement partially by redmud in
materials (SCMs). The investigation was attempt to partially replace cement up to 50% with SCMs, including limestone powder (LSP), rice husk ash, silica fume (SF) and kaoline (KL), and to verify the synergistic effect in ternary and quaternary system. On the basis of 30% LSP replacement, the incorporation of either 20% SF

decrease monotonically as the replacement percentage of cement with glass powder increases. The workability decreases when cement is replaced partially with glass powder. † The present study shows that there is a great potential for the utilization of glass powder in concrete as partial replacement of cement. About 30% of cement may be
