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.
This webinar will review issues that should be addressed when preparing a specification for concrete repair. ICRI developed an editable specification titled “Guide Specification for Structural Concrete Repairs” that can be used by design professionals. The webinar reviews the specification and discusses decisions that should be considered when developing a concrete repair specification.
This session will describe the use of tensile pull-off (bond) testing for concrete repairs and bonded overlays. It will provide guidance on applications of the test, industry standards and guidelines, acceptance criteria, proper testing procedures, appropriate equipment, and interpretation and reporting of test results. Bond is important because it relates to structural requirements (e.g. for strengthening and structural repairs) and for durability requirements (e.g. for overlays and cosmetic repairs). Testing of bond is needed to verify that the specified bond requirements have been met and a satisfactory result has been obtained.
This webinar will discuss the keys to proper surface preparation including establishing the appropriate level of surface profile, evaluating the concrete substrate and the material being installed to determine the correct level of preparation as well as the correct methods and tools to achieve that level.
Industry experts Eric Muench and Dan Wald will discuss how to best select the right traffic bearing waterproof membrane technology for concrete protection.
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 floor covering and coating failures are a very costly and disruptive issue with the direct and in-direct costs associated with such issues estimated to be in the hundreds of millions of dollars each year in the United States alone. In this session, a brief overview of the previous sessions will be provided and experts in the field of slab moisture, concrete, testing and forensics will answer your industry questions related to the subject.
The mitigation of moisture in concrete floor slabs has become an entire sub-industry to the placement of concrete floor slabs that will receive a moisture-sensitive floor covering or coating. In this webinar, attendees will learn what approaches are being used to mitigate an unacceptably high level of moisture in a concrete floor slab and what pre-installation evaluation procedures are necessary to help ensure the success of a moisture mitigation strategy.
