Accelerators

Non-Chloride Accelerators

  • AdvanSet NC

    Riteks AdvanSet™ NC is a is a non-chloride, water-reducing accelerator for concrete. It promotes higher early and ultimate strengths; especially in concrete exposed to temperatures below freez-ing. Concrete placed in colder weather with AdvanSet NC is able to maintain normal set times without the introduction of chloride-bearing components. AdvanSet NC is recommended for use in: precast, site cast, and all other steel reinforced concrete.

Calcium Chloride Accelerators

  • AdvanSet

    Riteks AdvanSet™ is an accelerating admixture designed to advance the normal set time of concrete. This calcium chloride based admixture is multi purpose as it improves workability, compressive and flexural strengths. This material is compatible with all of the Riteks admixtures including the high range and mid range water reducers.

Air Entrainers

  • A-Train FF

    A-Train FF is a specialty solution of selected surfactants for use as an Admixture for Cellular and Pre-Foamed Lightweight Concrete and for use as a Synthetic Air Entraining Admixture for Concrete. When used with a Foam Generator and a suitable water supply, A-Train FF produces a consistent pre-foam that is stable under alkaline conditions and suitable for use in the production of foamed concrete. Foamed concrete results from the controlled addition of a pre-foam to a cement grout or sand/cement mortar. Typically, producers can achieve a range of densities, from 20 to 100 lb/ft³. Foamed concrete is lightweight and highly mobile, able to flow for long distances under its own hydraulic head, and is an ideal material for uses such as void filling, roof screeds and trench reinstatement

    Features and Benefits

    • Produces a consistent, stable pre-foam when used with a foam generator
    • Easily controlled addition of pre-foam to pre-batched mortar allows close control of finished density
    • Mixing in the drum of a ready mix truck eliminates the need for expensive blending equipment
    • Produces highly mobile foamed concrete that easily places without compaction.
    • Foamed concrete retains its volume and does not sink during or after hardening
  • A-Train VR

    Riteks A-Train™ VR is a neutralized vinsol resin concentrate admixture for entraining air in concrete. A-Train VR will increase resistance to damage from cyclic freeze/thawing and scaling from deicing salts and will improve plasticity and workability.

  • A-Train PR

    Riteks A-Train™ PR is an admixture for entraining air in concrete. A-Train PR introduces millions of uniformly sized spaced air voids throughout the concrete mixture and is far more resistant to freezing and thawing than plain concrete. A-Train PR in hardened concrete reduces permeability and enhances the resistance to surface deterioration caused by de-icing chemicals.

Dry-Cast & Masonry Products

  • Riteks ES-2000

    ES-2000 is specially formulated for cost efficient production of concrete masonry and pipe units. It has the ability to aid in the dispersion of cement particles to promote better early strengths. Masonry and pipe units manufactured using ES-2000 have a better appearance (medium to heavy swipe depending on materials) and are less abrasive on mold equipment.

    ES-2000 may be used wherever increased and improved masonry production is required. It is particularly useful in:
