Slag Cement Shipments Increase
- Tuesday, 11 February 2020 07:10
Slag cement shipments in 2019 increased 10.8% over 2018 totals, says the Slag Cement Association (SCA). This marks the fourth consecutive year of double-digit growth in shipping totals across the United States.
SCA attributes this rise in part to slag’s measurable benefits in concrete, including better workability and finishability, reduced thermal stress, higher compressive and flexural strengths, and improved resistance to aggressive chemicals.
“We have seen a substantial increase in slag cement use as concrete professionals become more and more familiar with the product,” said Ed Griffith (St. Marys Cement/Votorantim Cimentos) and President of the Slag Cement Association. He is also 2nd Vice-Chairman of the ACPA Board of Directors.
Reducing the carbon impact of concrete is becoming an important factor in construction material choice. Slag cement is a recovered material from the iron production process and because of this, reduces the environmental impact of concrete mixtures by decreasing carbon footprint, embodied energy and the use of non-renewable materials.

Essroc to Acquire Slag Cement Grinding Facility
- Thursday, 23 April 2015 14:36
Essroc Italcementi Group* has signed an agreement with Holcim* to purchase its slag cement grinding facility in Camden, N.J.
As part of the transaction, Essroc will also obtain Holcim’s cement terminal in Everett, Mass. The acquisition will finalize when the pending Holcim and Lafarge merger completes later this year.
“The acquisition of the Camden slag grinding facility reiterates Essroc’s commitment to the northeast market,” said Francesco Carantani, Essroc’s President and Chief executive officer. “With the focus on sustainability and durability, there is a projected growth in the demand and usage of slag cement.”
The Camden facility can produce upwards of 700,000 metric tons of slag cement annually. Essroc currently produces slag cement at its Picton, Ont., and San Juan, Puerto Rico, cement plants, as well as at its slag grinding facility in Middlebranch, Ohio. With the addition of Camden, Essroc has a combined annual production capacity in excess of one million metric tons. Holcim’s staff in Camden and Everett will join Essroc once the transaction completes.
Slag cement, or ground granulated blast-furnace slag (GGBFS), is a cementitious material that is a byproduct of steel production. It works synergistically with portland cement to increase strength, reduce permeability, improve resistance to chemical attack and inhibit rebar corrosion. As a green building material, slag cement can be used in virtually all concrete applications.
