Trinic CS Densifiying Additive (22.73ltr)


1 in stock


CS is a colloidal silica concentrate for use as an internal part of a concrete mix. It ranges in particle size of 1-100 nanometers. Colloidal silica reacts with the free lime in the concrete matrix to make a more dense surface / mix.


  • Highly reactive suspended crystals fit between cement grains providing a nucleation site for the precipitation of CSH gel
  • Accelerates the early strength gain of concrete with minimal affect on initial set
  • Improves particle packing at a nano scale, which leads to a denser concrete with less bug holes
  • Improves the concrete’s microstructure and reduces water permeability
  • Improves compressive and flexural strength 10% – 30% depending on dosage
  • Helps eliminate effloresce
  • Improves the bond between cement matrix and aggregates, which is especially important in glass mixes
  • Improves mix cohesion, allowing a flowable GFRC mix to be sprayed on vertical surfaces, and prevents segregation in highly plasticized mixes
  • Five gallons of Trinic CS Densifying Additive is equal to the power of one ton of ordinary pozzolans such as silica fume, Metakaolin, bottle Pozz, or VCAS
  • Accelerates the strength gain of concrete containing pozzolans — in many cases 50% or more of the cement can replaced with a pozzolan without the loss of next day strength
  • Contains dispersants to prevent clumping


When adding to a mix, replace up to 5% of your water by weight with CS Densifying Additive
