AASHTO T-259 Test Results — Summary of Chloride Ion (salt) Penetration, % Chloride Ion

CreteDefender P2 virtually eliminates the threat of salt damage and of chloride ion penetration, a leading cause of deterioration of reinforcement (rebar). In tests conducted by Bowser-Morner, a leading independent testing laboratory, chloride (salt) penetration in concrete treated with CreteDefender P2 was cut by 55% in tests of CreteDefender P2 performed in accordance with the AASHTO T-259 standards. In this test, samples were subjected to 90 days of ponding of a 3% chloride solution.
ASTM C-1202/AASHTO T-277 Test Results — Summary of Chloride Ion Permeability, in Coulombs
| Test Condition | Air Entrained at 5.1% | Non-Air Entrained | ||
| Untreated | 6173 (high) | 7806 (high) | ||
| Treated | 2849 (moderate) | 3089 (moderate) | ||
| % Improvement | 54% | 60% |
Bowser-Morner also conducted tests in accordance with the ASTM C-1202/AASHTO T-277, which measure the changes in electrical current conducted through the concrete, to determine chloride ion concentration. In these tests, treating concrete with CreteDefender P2 cut chloride (salt) permeability by 54% in air entrained concrete and 60% in non-air entrained concrete. These results indicate that corrosion of rebar and the resulting deterioration of the concrete will be delayed by years, if not eliminated entirely.
