CTS Cement Announces Environmental Product Declarations (EPD) for Flagship Brands

Independent analysis confirms manufacturing belitic calcium sulfoaluminate (BCSA) cement is more environmentally friendly than manufacturing portland cement.


(Garden Grove, CA) – It’s easier than ever for North American concrete producers to use CTS Cement Manufacturing Corp.’s belitic calcium sulfoaluminate (BCSA) cement instead of portland cement to meet public and private project owners’ sustainability goals for concrete. A Type III environmental product declaration (EPD) developed by Los Angeles-based Labeling Sustainability Inc. is available for the company’s two flagship brands: Komponent® shrinkage-compensating cement additive and Rapid Set® Cement.

This is the first EPD for BCSA and the shrinkage-compensating additive Komponent in the world.

Durability Increases Energy Efficiency

  • Komponent® is an ASTM C845-compliant shrinkage-compensating additive blended with local portland cement to make Type K shrinkage-compensating concrete and grouts for transportation, tunnel, water and wastewater containment, industrial floor, and commercial building construction. In addition to thwarting curling and cracking caused by drying shrinkage, the additive enables project designers to significantly reduce or eliminate control joints.
  • Rapid Set® Cement is an ASTM C1600-compliant cement that can achieve 4500 psi compressive strength at 1.5 hours. Unlike other CSA cements, it doesn’t require blending with portland cement or additives.


For these reasons, architects and engineers already specify Rapid Set-based products to earn a variety of U.S. Green Building Council Leadership in Energy and Environmental Design (LEED) credits for LEED Silver, LEED Gold, and LEED Platinum certification. The Type III EPDs further support a project owner’s efforts to use environmentally beneficial materials.

A wide and complex range of variables affects the environmental impact of every concrete mix.  Our experts in CSA technology are eager to answer questions and help producers and project owners calculate the potential benefits of replacing portland cement with Komponent or Rapid Set Cement.

“The EPDs confirm what we’ve known for decades about the environmental benefits of using our products,” says CTS President and CEO Ken Vallens. “To address climate change, federal, state, and local government agencies are setting carbon-reduction and other green-building goals. Our technical experts are on call 24/7 to help architectural, engineering, and construction (AEC) firms and concrete producers understand how to use these EPDs to meet these goals.”
