Trinic Stage II Blended Powder Hardener / Accelerator

  • $17100


Trinic Stage II Blended Powder Hardener / Accelerator

  • Blended powder hardener / accelerator admixture formulated specifically for the production of high performance thin section concrete.
  • Increases the early strength and ultimate strength of concrete
  • Offsets the retarding effects of high Plasticizer dosages while reducing pozzolan strength lag
  • Delivers excellent results in normal and cool conditions where very high next day strengths are required.
  • Curing times and heat requirements are significantly reduced while concrete quality is improved.
  • Does not contain calcium chloride or any other intentionally added chlorides and will not initiate or promote the corrosion of reinforcing steel
  • Less chance of warpage, curling, or cracking
  • A must for winter concrete
  • Increase strength gains as much as 50% overnight.
  • Designed to work with Trinic’s GFRC Admix

 

Concrete goes through three distinctive hardening / curing stages. During the first stage little or no strength is gained. During the second stage as much as 1,000 PSI per hour in strength gains can be realized, and during the third stage strength gains of 50 PSI per hour happen. Ordinary accelerators start working the second they contact the cement, shortening the working time of stage one. Trinic Stage II accelerator / hardener is designed to start working during the second stage of strength development.

Dosage:

  • .5% to 4% of the cementitious weight: see results below.

Test Results:

Test 1 – Control, no accelerator: GFRC 60-60 (90-10)-18 about 1 cubic foot

  • 54 lbs. Federal type I white cement – 90%
  • 6 lbs Trinic Bright White Silica Fume – 10%
  • 60 lbs. Q-Rok #1 Silica Sand from US Silica Corp
  • 18 lbs. potable water
  • 3% Trinic, GFRC Admix (3% of 60 = 1.8 lbs)
  • Overnight Cure – started at 70 degrees, covered with plastic and insulating blanket, no additional heat used.  Sampled were cured in 72 degree water after striping the next day.
  • Mix consistency – Flowable, would make a good spray coat
