Trinic Pozz Plus - GFRC Made Easy Admix

Trinic Pozz Plus - GFRC Made Easy Admix

• Simple, convenient, and cost effective solution to mixing GFRC, RPC, and ECC mixes.
• Pozz Plus is a dry powdered blend of White Silica Fume, Tec-10 Polymer, and other admixtures.
• All you have to do is replace 10% of your cement weight, with 13% weight of Pozz Plus- and create super strong, high performance GFRC, RPC or ECC.
  • (You still add chopped fiber (sold here) when applicable/backer coats, and can add optional Plasticizer (sold here) to create self-leveling (SCC) mixes.
  • Simplifies the mixing process (less chance of human error)
  • Includes the high quality, UV stable micro polymer (Tec 10) product, which eliminates the need for a 7-day wet cure for GFRC.
  • Includes Anti-Foaming agents to eliminate pinholes.
  • Improves color dispersion, intensity, and stability- which results in better color on final pieces.
  • Includes specialized additives for water reduction.
• Pozz Plus increases density.  Increases compressive strength.  And increases flexural strength up to 200%
  • Pozz Plus helps eliminate surface crazing, bowing, and curling of the concrete pieces.
  • Increased density will close internal capillaries in the concrete, leading to more acid and stain resistant concrete.
  • Adding Pozz Plus will allow faster GFRC mixing times, less cement clumping issues, and a more homogeneous mixes (even if you have a less than ideal mixer)
• Stage II Accelerator (sold here) can also be used with Pozz Plus, to increase early strength gains (allows demolding even quicker for GFRC pieces)
• Each bag contains a desiccant packet to keep the product dry. DO NOT USE (or eat)

Specifications: Trinic Pozz Plus - GFRC Made Easy Admix

• Standard product is the 20lb Bag.  Pallets available in 50 bag, and 100 bag qty.
• Coverage: 20 lbs. when replacing 10% cement weight with 13% weight of Pozz Plus, will make up to 36 sq. ft. @ 3/4" thick.
• Temperature and Curing: Concrete batch temperature should stay below 70°F for effective workability time.  Do not let the mix exceed 140°F during the curing process.  Using ice as part of the mix water is an effective way to lower the batch temperature.  Concrete should be covered with plastic to maintain moisture and strength gains, as well as prevent problems such as warpage, and dry shrinkage cracks.

Dosing / Mixing Instructions Trinic Pozz Plus - GFRC Made Easy Admix

Dose Pozz Plus by replacing 10% of your cement weight, with 13% weight of the Pozz Plus.  

MIX DESIGN: Example high performance mix design:

• BASIC GFRC MIX (@ 1/2 Cubic Foot Yield)
  

  This is enough to produce 8 square feet of GFRC ¾” thick.
  (Backer Coat is just the Face Coat mix, but with chopped glass fiber added in the range of 2-4% of the total dry weight of the batch)
  
  
  • We recommend White Portland cement, but Gray can be used as well.
  • Always make a test batch prior to production runs
    
    
  • Sand graded anywhere from 30 grit (fairly course) to 70 grit (very fine) can be used
  • Recommend starting with a 40-50 grit sand for face coats and back coats.
    • (You can offset thirsty fine sand with additional Plasticizer)
      
      
  • Basic Recipe: 50% Cement, 50% Sand:
    • Cementitous: Portland Cement 30 lbs
      • When using Pozz Plus: 27 lbs Cement, 3.9lbs Pozz Plus:
        • Replace 3lbs of Portland cement (10%) with 3.9lbs of Pozz Plus (13%)
    • Sand: 30lbs
    • Water to cement ration: 0.30 to 0.34.  Which is about 9lbs of water, or a little over 1 gallon usually (varies, based on sand used, etc.)
    • For Backer Coat: Add @ 1.8lbs of Chopped Fibers
      • (Fiber added at 3% by dry weight of total mix)
    • For Self-Consolidating (SCC) just add Plasticizer at 0.25% to 0.75% of the total cementitious content.  
      • When using Pozz Plus in this example recipe, total cementitous is 30.9lbs, so add plasticizer in the amount of 0.08lbs (1.28 ounces by weight)  up to 0.23lbs (3.68 ounces by weight)
        
        
  • Notes on Water Demand
    • Cement Type - Different cement types will have different water demands to reach the same slump. Not just white and grey, but cement from different mills will react differently.
    • Sand - The size of the sand grain and the sand type both have an effect on slump. Generally the finer the sand the higher the water demand.
    • The water to cement ratio is the total water weight divided by the total cementitious content weight.
    • The water in the sand or the absorption factor of the sand must be accounted for in order to calculate an accurate water to cement ratio.
    • Extremely wet sand can contain up to 10% moisture.
    • Dry sand can absorb up to about 2% of its weight in water. This is known as satisfying the sand’s absorption factor.
    • The sand absorption is largely responsible for the false set you may experience.
      
    • DRY SAND EXAMPLE:
      • Example with dry sand.  30 lbs of sand and 30 lbs of cement... How much water gives you a .3 w/c ratio?
      • 30 lbs of cement * .3 = 9 lbs of water
      • 30 lbs sand with an absorption factor of 1.5 = .45 of additional water to satisfy the sand’s absorption
      • Adjusted water to achieve a .3 w/c ratio is 9.45 lbs
