  • Where is slag cement used?

    What are the advantages of using fly ash or slag? Fly ash and Slag will typically be 18% cheaper than Portland cement. When a mix includes 20% fly ash, this will provide savings of % 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 content ratio.
