dry concrete. Definition. Concrete that has a low water content, making it relatively stiff. The effects are a lower water-cement ratio, less pressure on forms, lower heat of hydration, and a consistency that allows for placement on a sloping surface.
1 Portland cement is produced by burning a slurry of finely crushed, high-calcium limestone, clay, sand, and a small amount of iron ore in a cement kiln. 2  The pelletal material exiting the kiln is called âclinker.â Gypsum is added, and the clinker-gypsum mixture is finely ground into Portland cement. It is used as a soil conditioner to neutralize acidity and to add calcium and magnesium nutrients. 2  Quicklime is calcium oxide (formula CaO) that is produced by calcining (burning) high-calcium limestone in a lime kiln to drive out the carbon in the form of carbon dioxide gas (formula CO2).
