Why use Fly Ash and Slag in Concrete? - Bay-Lynx

Fly ash and Slag will typically be 18% cheaper than Portland cement. When a mix includes 20% fly ash, this will provide savings of 3.5% in cost. The advantage of slag is its ability to substitute more of cement. Giving savings of up to 9% in cement cost with a 50% slag to cement

Steel Slag - User Guideline Asphalt Concrete - User

INTRODUCTION. Steel slag can be processed into a coarse or fine aggregate material for use in dense- and open-graded hot mix asphalt concrete pavements, (1,2,3) and in cold mix or surface treatment applications. (4) Proper processing of steel slag and special quality-control procedures are extremely important in selecting steel slag for use in asphalt paving mixes.

Slag - Wikipedia

Slag is the glass-like by-product left over after a desired metal has been separated (i.e., smelted) from its raw ore.Slag is usually a mixture of metal oxides and silicon dioxide.However, slags can contain metal sulfides and elemental metals. While slags are generally used to remove waste in metal smelting, they can also serve other purposes, such as assisting in the temperature

cement | Definition, Composition, Manufacture, History

Cement, in general, adhesive substances of all kinds, but, in a narrower sense, the binding materials used in building and civil engineering construction. Cements of this kind are finely ground powders that, when mixed with water, set to a hard mass.Setting and hardening result from hydration, which is a chemical combination of the cement compounds with water that
