Early (circa 1950's) research,  clearly showed that a "disrupted" capillary system will significantly lower the permeance of concrete....and thus defeat the "transport system" so detrimental in concrete. B  This one action alone, may be the most important function in combating water/damp proofing, moisture/vapor proofing and fighting all kinds of steel corrosion; chloride, sulfate, and MIC. At the heart of our technologies, are several industry leading pozzolanic Integral Admixtures that swiftly and permanently disrupt the formation and function of the capillary system.  They achieve this by creating additional c-s-h product - cement hydration.  No ultra-low mix design restrictions ~ but everyday concrete mixes used in large production situations; Designed, Targeted and Tested to reach an Ultra Low Permeability Concrete - naturally, through pozzolanic (SCMs) action/re-hydration admixtures.
