In the modern era of fast construction practices due to the inappropriate use of various suer-plasticisers, admixtures and improper curing methods scaling is one of the rapidly upsurging complications in exposed concrete. This problem can be seen in many structures which had insufficient curing and porous finishing layer. Excessive use of deicing salts, severe exposure of concrete and improper mix design add acute complexities to scaling. Main reason for scaling is porous finishing surface. This problem can be solved by using silica fume as it fills the voids between cement particles. Other reason is cyclic expansion and contraction of entrapped water which not only widens the pores but also leaves behind harmful chemicals in residual form. These chemicals can not reside if concrete already possesses the acidic properties. In this research, we used silica fume as partial replacement of cement and mildly acidic industrial wastewater in concrete. Results show that when silica fume is added by 20% of cement and industrial wastewater is added in same proportion as potable water chloride concentration can be reduced by 35% which can be very useful in preventing the scaling.
