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.

Short Description:
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:
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:
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.
