  If all you had to worry about was turning rawmix into clinker. But it's not. You have to make the rawmix, you have to powder the clinker, you have to ship in the fuel, the limestone, the shale or clay, package and ship out the Portland cement. You need to provide instructions on the mixing of the Portland with water and aggregate, on the pouring and how long your customers will have to make the pour after mixing.
