    Admixtures

    Admixtures from various manufacturers can impact the performance of any mix design. Roman Cement has worked with all the major admixture suppliers and can help you get the most out of those resources

  • Testing

    Once Roman Cement has refined our mix designs to work with your aggregates and admixtures, independent testing can be performed to ensure the product meets your expectations.

Perfect for both Commercial and Residencial Projects

The City of Salt Lake and the Utah Transportation Authority:

Electric Bus Charging Station

The City of Salt Lake used Roman Cement in their Electric Bus Charging Station.

By using Roman Cement’s concrete mix designs…they were able to reduce the carbon footprint of this project by more than 20% compared to their standard mix, while improving the strength and durability of the concrete pad for this important Bus charging station.

The Yalecrest Historic District is located on the East Bench of Salt Lake City. It is locally significant both architecturally and historically.

These districts are made up of residences exhibiting a variety of period revival styles dating to the first few decades of the 20th century.

Roman Cement has been used by the upscale residents because they value a long-lasting, low-carbon concrete on these priceless, historical properties.

Our Patented Technologies: Improving Durability, Strength, and Workability

  • How They Work: Our patented technologies replace 20-50% of the Portland Cement in a conventional concrete mix with more solid, low-carbon minerals that optimize the particle distribution and minimize the air pockets of a mixture.

  • Better, More Sustainable Concrete: This substitution and particle optimization results in concrete that:

    • Reduces the Carbon Footprint by 20-50% as compared to conventional concrete

    • Is More Durable Against:

      • Freeze-thaw damage

      • Salt-water attack

      • Shrinkage

    • Reflects Improved:

      • Compressive strength

      • Workability
