    Abstract

    This research was undertaken to study the effect of sulphate activation of Run of Station Ash (ROSA) blend with Red-Gypsum (RG), Plaster Board Gypsum (PG) and By-Pass Dust (BPD). Tests were prepared using binary and ternary steps. All mixes had similar water to binder (w/b) ratio of 0.3% and the water content was reduced in last mixes to obtain more compressive strength. Results showed PG and RG can be used as sulphate to form a sulphate activated pozzolan BPD-ROSA binder which could be used for low strength construction materials. The source of by-product material, BPD and ROSA, affected the material characteristics and mixtures.
