Both fly-ash and slag are used as additives in the production of blended cement. 3. Selling expenses. Since cement is a low-value, high-volume commodity, freight costs constitute a significant proportion, around 20-25 per cent, of the total cost of sales. There are three major modes of transport used by the cement industry i.e. road, rail and sea.
