Portland cement is a finely ground, manufactured mineral product that when combined with water, sand, gravel, and other materials forms concrete the most widely used construction material in the world. The Portland cement industry in Ohio consists of five plants; Fairborn, Paulding, East Fultonham, Middlebranch, and Sylvania. These plants combine to produce 2,500,000 tons of cement a year. Of these plants, Fairborn is the largest and most fuel efficient. Paulding is innovative in using industrial solvents as a fuel addition for its kiln. Middlebranch is the smallest plant (600 tons per day), and gets its stone from a sister plant. East Fultonham is a sister plant to Sylvania. Sylvania has been shut down for almost two years, so East Fultonham uses the dormant plant as a terminal for northwest Ohio. There are three different cement processes used in Ohio. The wet, dry, and semi-dry kiln process. The wet process is used in three plants; East Fultonham, Paulding, and Sylvania. The dry process is used in Fairborn, and the semi-dry process is used at Middlebranch. Of the three processes, the dry process is the most fuel efficient, so ...
