  • Concrete Additives

    Concrete additives can improve the overall workability of a concrete mix by enhancing certain properties allowing you to achieve a variety of results.

    Some of the additives we use include:

    • Air entrainment - Helps prevent freeze/thaw cracking
    • Fly ash - Commonly added to the cement portion of the mix
    • Water reducer - Gives concrete more workability without weakening the mix
    • Superplasticizers - Allows high slump concrete without added water
    • Retarder - Slows the curing process for long-distance delivery or to give the contractor more time to work the concrete
    • Accelerators - Increases the rate of early strength development and/or shortens setting time
    • Fiber - Protects against plastic shrinkage and cracking.
    • Structural Fiber - Reinforces concrete and potentially reduces the cost of wire mesh
    • Corrosion Inhibitors - Reduces the corrosion of steel reinforcement
    • Water Proofing - Allows for water proofing of concrete slabs
    • Hot & Chilled water - Allows placement of concrete during extreme temperatures
  • High Early Mixes

    When design strength needs to be achieved in less than 28 days, our MoDOT-approved High Early mixes will achieve design strength in 7 or as few as 3 days. Our High Early mixes get strength fast to help you complete the job faster.
