Tests Support Use of Spray Dryer Absorber Products in Making Cement and Concrete
Characterization of Spray Dryer Absorber Products for Use in Cement and Concrete Applications (EPRI Product 1017580).  Working toward increasing the use of spray dryer absorber (SDA) products, researchers characterized their physical, chemical, and mineralogical properties.  They compared SDA product properties with those described in the ASTM C 618 standard specification for using fly ash in portland cement concrete.  Samples from eight power plants met enough of the standard specification criteria to show promise for use in cement and concrete applications.  This Technical Report is available at no additional cost to funders of Program 78; others are welcome to purchase it.  For more information, contact Ken Ladwig, (262) 754-2744, keladwig@epri.com.
