- 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.

- Short Description:
- Concrete is one of the most versatile building materials in the world and can produce floor slabs that provide an excellent platform for floor coverings and coatings. Water is an essential component of every concrete mixture. Without it, concrete is not workable and finishable. If water is not used, the cement in the mixture cannot hydrate and gain the required strength. However, once placement, finishing, and curing is complete, remaining moisture in the concrete can adversely affect the installation of flooring materials and the behavior of the slab itself. This webinar will discuss the importance of water in a concrete mixture and review a few concrete problems that water can cause, such as shrinkage, curling, ASR, delamination, dusting, and scaling. In addition, attendees will learn the design and construction considerations that can be used to minimize the potentially adverse effects of moisture in concrete.

- Codes and standards are developed for use by design professionals; however, the use of codes and standards significantly impacts Owners and Contractors. The ACI 562 code was motivated by the poor performance of repaired concrete structures, specifically premature failure of repairs and limited durability of repaired structures. Development of the code was intended to benefit owners and contractors by improving performance and perceptions regarding repairs to existing structures.

- Short Description:
- Matching concrete sounds simple, but there are many factors that affect color, texture, and aesthetics. There is often a challenge with using modern cementitious materials for matching older and historically manufactured cements. Whether your project is historic or contemporary, this presentation will outline materials and methodology that are important to understand when concrete matching is important. With many mid-century buildings coming of repair age, this is a critical time for understanding these concepts. The presentation will include the fundamentals of concrete materials, how cementitious materials affect concrete color, how to use color measurement technology in developing a color match mix design, how aggregate exposure affects aesthetic perception, and other helpful tips when it comes to matching concrete for durable and aesthetic results. Regionally available materials will vary, but the methodology for color matching durable repairs is fundamentally the same.
