In specien no II mortar with 10% of Silica Cement Admixture has been dipped in 5% Sulfuric Acid making three samples 1, 2 and 3. In specien no I mortar with 0% of Silica Cement Admixture has been dipped in 5% Sulfuric Acid making three samples 1, 2 and 3. The weight of all specimen were taken before dipping on sulphuric acid ( H2SO4). After that the weight of specimen was taken on every 1 week, 3 week and 6 week time. The change in weight was recorded. The below table shows the change in weight in each specimen.
We can see mass change is less on those specimen with more silica. It shows silica is better effictive to use on those concrete structure which might come on contact with chemicals.
