ABSTRACT Mineral and chemical admixtures are used today in most concrete mixtures to improve the recent and hardened properties of concrete and to increase the durability of concrete During this study four minerals and 4 chemical mixtures were studied in particular metacoline MK silica fume SF category F ash FA blast furnace slag BFS 2 high level water reducers SP water slow motion reducer WRD and inlet air AEA The objective of this study is to evaluate the consequences of mineral and chemical additives not used in concrete strength The properties studied here include setting time compressive strength and magnification when exposed to a sulfate solution The results of this study indicate that the inclusion of oxide fumes maintains greater strength than the opposing mineral mixtures considered here Up to 100 replacement levels have surpassed the opposing mixtures studied The ash showed an improvement in the workability of the mixtures however it had lower compression resistance results and could create challenges once the strength gain rate is crucial However the ash blends of category F showed a higher yield than non homogenized mixtures once exposed to a sulfate supply Metakaolin mixtures showed a greater heat evolution among all the mixtures studied here this will probably cause robustness problems particularly once the temperature increase can be a design problem Blast furnace scum additionally improved the workability of the mixes and therefore the later compressive strength however had mixed performances once examined for sulphate sturdiness
