INFLUENCE OF SLAG ON SODIUM SULPHATE RESISTANCE OF MORTAR CONTAINING DESULPHURISED WASTE

摘要：

The beneficial effect of using slag in mortars containing simulated desulphurised waste (SDW) is reported. Mortar specimens with varying amount of SDW and slag were prepared. The binder to sand ratio and the water to binder ratio were maintained constant at 1:3 and 0.55 respectively. The binder consisted of cement, SDW and slag. Specimens were exposed to 2.2％ sodium sulphate solution. A previous investigation reported the increased resistance to sodium sulphate solution in mortar containing SDW. The results of this work indicate that the presence of slag in mortars containing SDW exhibited superior resistance in sodium sulphate solution. Replacing cement with slag above 20％ did seem to further increase the sulphate resistance.
