Feb 21, 2013 To make concrete, you combine water, sand, gravel, Portland cement and, in many cases, fly ash. Despite representing only a small fraction of concrete's principal ingredients, Portland cement produces 1 ton of CO2 per ton of cement during its manufacture. One ton of fly ash can replace one ton of Portland cement; thus emitting one less ton of ...

How Concrete is Made. In its simplest form, concrete is a mixture of paste and aggregates, or rocks. The paste, composed of portland cement and water, coats the surface of the fine (small) and coarse (larger) aggregates. Through a chemical reaction called hydration, the paste hardens and gains strength to form the rock-like mass known as concrete.

London coal gas production began in 1813 and by 1842 was producing 300,000 tons of coke a year, so coke was also readily available, and, being essentially a waste product, was cheaper than coal. Early cement plants used coal for drying slurry and for power generation, and coke for kiln burning.
