Concrete Definitions

f Prime: The specified compressive strength of concrete in PSI

Air entrainment: All our mixes are chemically air-entrained. This means microscopic bubbles are introduced into the fluid concrete, allowing expansion and contraction of the hardened concrete. This provides increased resistance to temperature changes (freezing and thawing) and minimizes cracking. Air-entrainment also greatly improves workability, giving semi-liquid concrete a “creamy” look and feel. Less water is required in all mixes, and the billions of air bubbles (400-600 billion per cubic yard) reduce “bleeding” (separation of the water from the paste), resulting in a more durable concrete.

Slump: The term “slump” refers to the fluidity or stiffness of semi-liquid concrete. Unlike ready-mix, our truck operator controls the amount of water being added to your mix as it is being delivered, assuring you the slump you desire.

Fiber Mesh: Fiber mesh is a mass of small polypropylene fibers that can be added to your mix upon request. The fibers are uniformly distributed throughout the mix and provide added protection from cracking due to shrinkage and expansion. Replacing rebar and/or wire mesh. Fiber mesh is $12 per cubic yard.

Accelerator: is used during the winter months to help the chemical process start in cold weather, so finishing can be completed properly. Hot water comes with a mandatory charge from November through March.
