The Difference in Slag Cement and Fly Ash

The Slag Cement Association with member company and industry input have broken down the differences in slag cement and fly ash and how they both affect concrete performance. 1: Slag cement has a more consistent chemical and physical structure than fly ash from source to source and from a

Slag cement with fly ash

Fly ash is a byproduct of electric power generation that varies from source to source. Concrete Properties. Slag cement is a more uniform product than fly ash. As a result, concrete made with slag cement will generally have more uniform properties than concrete made with fly ash. Plastic Properties. Water Reduction. The use of either material

Slag Cement: A Valuable SCM to add to Your Concrete

Slag cement, like portland cement, is a hydraulic cement—it chemically combines with water to set and harden. Because slag cement has a more consistent chemical and physical structure than fly ash, it produces cement paste and concrete with more consistent performance results.

Apr 17, 2017· I had practically used PPC cement in almost all projects. I didn't find any problem. Portland Slag Cement (PSC) Portland Slag Cement (PSC) is manufactured by either inter-grinding in the Portland cement clinker, Gypsum & Granulated Slag or blendin.

Fly Ash Topic American Concrete Institute

Fly ash is a by-product from the combustion of pulverized coal, and is widely used as an ingredient in hydraulic-cement concrete. Because it improves many desirable properties of concrete, it is introduced either as a separately batched material or as a component of blended cement. Fly ash reacts with the hydrating hydraulic cement to form a cementing medium.

Fly Ash Trends Downward National Precast Concrete

Mar 27, 2017· As a result, New England and the Virginias switched from fly ash to slag this year. Regardless of the current supply status, the days of having an affordable, reliable source of fly ash are nearly over. A decade ago, fly ash was largely viewed as a supplement to cement and was used because it was half the cost of cement.
