The performance of Surtreat's chemistry has been verified by numerous independent engineering-consulting firms in the field as well as through extensive independent laboratory testing. The results of the testing reflect the following typical result characteristics:
- Reduced Rebar Corrosion Potential - ASTM (American Society for Testing Materials) C-876 - Half-cell potential showed a reduced voltage by 70% in 14 days (0.8 to 0.3)
- Water Penetration Reduction - 100% resistance after 14 days exposure to 6-inch column of water. 75% resistance after 28 days exposure to 6-inch column of water. 90% resistance after 24 hours when 100 psi is applied.
- Freeze Thaw Resistance - ASTM C-672 -50 cycles with no surface loss. AASHTO (American Association of State Highway and Transportation Officials) T-161 - 146 cycles with no surface loss.
- Chloride Penetration Resistance - AASHTO T-250 -30% decrease at 1-inch depth.
- Water-soluble Chloride Reduction - Reduced by 58% and 67% at 1 and 2 inches, respectively.
- Increase in Hardness - ASTM C-418 - 14% increase in hardness of new concrete. ASTM C-414 - 64% increase in hardness of deteriorated concrete. ASTM C-501 - 1,000 cycles with a 38% increase in wear index.
- Reduced Rebar Corrosion Potential - ASTM (American Society for Testing Materials) C-876 - Half-cell potential showed a reduced voltage by 70% in 14 days (0.8 to 0.3)
- Increased Surface Adhesion - No failure of epoxy bonded to treated surface.
- Reduced Chemical Reactivity - Resists reaction with concentrated hydrochloric acid
- Flexural Strength - Increased from 423 to 543 psi.
- Increased pH Level - Edges of concrete increased from 5 to 9, center of concrete increased from 9 to 12.
