From coal to concrete fly ash is re cycled into

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 Portland Cement Association

How Concrete is Made Portland Cement Association

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.
