Project description

Concrete mixtures can be made to be durable, even in extremely aggressive environments common in Florida. Deterioration is often caused by water and ion ingress into concrete through the concrete pore network. The resistance to water and ion movement into concrete, or penetrability, is measured by direct and indirect measures of the concrete pore system. As part of this phase I study, concrete specimens were made to test using surface resistivity (AASHTO T 358, bulk resistivity (AASHTO TP 119), rapid chloride permeability test (ASTM C1202), rapid chloride migration test (NT Build 492), volume of permeable voids (ASTM C642), water permeability, water absorption (ASTM C1585), concrete bulk diffusion (ASTM C1556), and concrete sulfate durability (ASTM C1012). This report documents the materials and mixtures used in this testing, methods used, and results.
