Can be Most Any Natural or Blended Rapid Strength Hydraulic Cement System
Intention is to Create a Cement Solution That All End User Has to do is Add Water and Aggregates
Admixture Friendly Bulk or Packaged Products

Very Rapid Hardening – 3000 psi 1 to 3 hours
Very Low Shrinkage – Volume Stability Limited Expansion No Carbonization No C3A in Chemistry – Sulfate Resistant Very Low Alkali – Addresses ASR Issues Low Heat of Hydration Low Porosity High Abrasion Resistance Coatings Can Be Applied Within Hours

User Friendly – Requires .45 to .50 water Cement Ratio – 4” slump without WRs
Most Traditional Admixtures Work Well with CSA – Including Corrosion Inhibitors
Reduce Permeability Using New Gen Polymers or Mod A Latex
Can Be Used With Cathodic Devices and Impressed Systems
LEED Points

Many Repairs in Containment Require Large Quantity of Grout as Some Type of Fill
Type K Grout Can be Delivered to Job Site in Conventional Ready Mix Trucks at 50% the Cost of Bagged Non-Shrink Grouts (material cost)
