RediMAX™


Documents marked as PDF require Adobe Acrobat Reader to view

RediMax™ is a versatile and flexible, high performance structural cement. RediMax™ can be effectively placed in ambient temperatures ranging from 30 to 120 degrees Fahrenheit without the need to follow traditional post hydration curing technique. RediMax™ is mixed and placed like conventional Portland cement, has up to 6 hours of working time depending on ambient temperatures and 1mix design. RediMax™ can be finished using standard concrete finishing practices. RediMaxwill achieve compressive strengths of more than 2000 psi within 6 to 72 hours depending upon mix design providing for ultra fast track construction. RediMax™ cement has virtually zero carbon footprint and will eliminate approximately one ton of harmful CO2 greenhouse gasses for every 3 yards of concrete produced.

Recommended Uses
RediMax™ is a structural concrete for roads and bridges, aviation runways, industrial infrastructure, boat ramps, building foundations and any other new construction application where rapid early strength gains are required.

Mixing Instructions
       Standard Mixing Procedures (Rotating Drum Transit Truck Concrete Mixer)

       CONTACT CERATECH FIELD ENGINEERING TEAM  FOR COMPONENT RATIOS
       1-888-341-2600

 
  • Determine volume of RediMax™ required for project
  • Pre-wet cement mixer with clean water then drain all water from mixer (away from placement area). Maintain rotation of drum at mixing speed.
  • For each Super Sack unit of RediMax™, add TBD lbs of fine aggregate (Sand SSD, Specific Gravity = 2.64)
  • For each Super Sack unit of RediMax™, add TBD lbs of coarse aggregate (ASTM #57 stone, SSD, Specific Gravity = 2.68 )
  • Add a total of TBD lbs (TBD gallons) of water including water within fine and coarse aggregate and * Air Entrainment Agent if required (See note below)
  • Add TBD gallons of RediMaxLiquid Admixture per each Super Sack of RediMAX™ used. ( To facilitate transit time, activator may be added at job site)
  • Mix for 7 minutes (Single Super Sack) Mix for 10 minutes (2 Super Sacks)
    (Slump may be adjusted with small increments of additional water )
  • RediMax™ can be discharged directly from transit truck into forms or into pumping unit hopper

       NOTES
  1. Use MicroAir from BASF only per manufacturers instructions
  2. Vinsol Resins or Tall Oil based Air Entrainment Agents are not compatible with this product


Application and Finish
  • Working times based on ambient temperature, types of aggregate and total amount of water.
  • Working times are influenced by surface temperature humidity and repair profile.
  • Minimum profile thickness is 3.00” (7.6 cm). There are no restrictions to the depth of the placement profile.
  • Upon initial set, a broom finish can be applied. Upon final set, the material can be saw-cut, drilled, sanded and/or polished
  • Do not re-temper. The addition of water to the surface of concrete will negatively affect the materials final properties.
  • General loading in 6 hours for wheeled traffic (Compressive strengths greater than 2,500 psi.)
  • Self-curing
  • Clean all tools and equipment with water prior to the material reaching final set.
