Sodium Thiosulfate

  • Sodium Thiosulfate is an additive that can improve early strength development in concrete. It works by delaying the onset of the retarding effect of sulfates in the mix. Sulfates can negatively impact the strength development of concrete, particularly in mixtures containing high amounts of Portland cement. By delaying the retarding effect of sulfates, Sodium Thiosulfate allows for faster strength development in concrete mixes.
