ACI Publishes Guide to the Use of Slag Cement in Concrete and Mortar

The American Concrete Institute (ACI) has recently published ACI 233R-17 Guide to the Use of Slag Cement in Concrete and Mortar. As slag cement use is rising in the U.S., understanding how slag cement works best in various situations is increasingly important for contractors and engineers.


The guide covers information on slag cement chemical properties and product types, storage, handling, batching, proportioning, and the effects on properties of fresh and hardened concrete. Various applications of slag cement are discussed including mass concrete, soil stabilization, and pavements. The guide concludes with an overview of how slag cement adds to the sustainability of concrete.

The guide can be purchased here through the ACI online bookstore. It is important to note that this guide only pertains to the use of Ground Granulated Blast Furnace Slag generated from iron ore production.


ACI 233R-17 Abstract:

”This report addresses the use of slag cement as a separate cementitious material added along with portland cement in the production of concrete. This report does not address slags derived from the smelting of materials other than iron ores. The material characteristics described and the recommendations for its use pertain solely to cement ground from granulated iron blast-furnace slag.”
