Abstract:
Can vapor retarders protect concrete slabs-on-ground from sulfate attack? The authors believe they can. To support this claim, the article discusses durability requirements in ACI 318, as well as exposure requirements in other industry standards and reports, and provides test data from evaluations of systems for isolating concrete from aggressive environments, a contractor- sponsored study, and a manufacturer-sponsored study.
