Concrete is the most widely used construction material and can be durable for hundreds of years; however, the main cause of concrete deterioration is from corrosion of reinforcing steel. Steel is thermodynamically unstable and will eventually oxidize to a lower energy state. The rate of deterioration in new and existing structures can be modeled to predict the service life based on the severity of the service environment, the concrete quality, the ingress of deleterious materials, and other factors to various degrees of success. This presentation will provide an overview of many of the service life models currently in use and provide an evaluation protocol for their application related to both new and existing structures.
Testing moisture in concrete doesn't need to be complicated. Five (5) currently recognized ASTM test protocols for testing concrete slabs for moisture will be explained using the "How and Why" perspective while providing the proper, yet basic, scientific context behind their usage.
Moisture-related problems with floor coverings and coatings are a serious and costly issue. Each year the direct and in-direct costs associated with such problems amount to billions of unplanned dollars. In this 5-part webinar series, experts in the field of moisture in concrete, testing, mitigation and repair will share information and experience in a ground up approach to the causes and solutions to such problems. The program covers the sources of moisture in concrete, the affect moisture has on slab behavior and the installation of flooring materials, the test methods used to properly assess slab moisture condition, moisture mitigation strategies, and more.
