Cracked concrete can lead to safety issues, water leakage, durability problems, shortened service life, poor aesthetics, and costly repairs. Minimizing cracking is a challenge, but fortunately, there are options to minimize and control concrete cracking. Concrete cracks because it fails in tension; and a common cause is shrinkage. This presentation will describe typical influencing factors that lead to concrete shrinkage, plus options and construction practices that can mitigate shrinkage to control cracking. This presentation will provide information that architects, engineers, and specifiers can use to enhance project specifications to help ensure more sustainable, and durable concrete construction.
This course will address the need for joints in concrete, while reviewing and explaining the current joint spacing recommendations. It will highlight the different options for extending joint spacing by showing some example projects. This course will also discuss the theory for using extended joint spacing in concrete slabs today.
This program takes a look at the unique challenges related to coating high-rise buildings. It begins with a discussion of how exterior waterproof coatings work. Participants learn the key to proper surface preparation and coating selection. Benefits and limitations of different coating chemistries are explored. The program will conclude with a discussion of best practices and troubleshooting common coatings applications.
This course explores the various means and methods of waterproofing vehicular and pedestrian decks through the use of liquid membranes. The course will introduce the learners to multiple technologies available in the market, and the proper procedures for installation that will result in an effective protection strategy for concrete decks.
This course will introduce the basics of grouting, such as the needs and successful applications. It will cover why we do it, what we use, and how it is done. The content includes an industry overview as well as discussion on grout technologies, installation procedures and tools of the trade.
This course will discuss moisture in concrete slabs and solutions to end slab moisture issues such as flooring failures, mold, warping or curling, and excessive drying times. One solution to these moisture related problems is utilizing a rapid drying concrete. Rapid Drying Concrete is a ready-mix concrete solution for preventing moisture-related floor covering failures, an industry-wide problem that costs millions of dollars annually in damage, downtime, repair and replacement.
Sustainability is a key element in product decision making. This presentation will provide you with information to support decision making for sustainable solutions, an understanding of key elements associated with quantifying sustainability and the need for holistic thinking. This course covers life cycle thinking for product selection and use, the components for sustainability as a balanced solution, specific elements that quantify sustainable results and the objective for multi-attribute decision making.
The intent of waterproofing is to prevent leakage from structures that hold liquids, such as water tanks and to prevent moisture from entering a living place, such as basements. This course is intended to help identify different options available to waterproof concrete, differentiate between the materials available for integral waterproofing of concrete, and understand the tests used to qualify waterproofing admixtures.
Part of the appeal of polished concrete is the honest expression of the material. The base color of the cement paste (and aggregates if exposed) combined with the natural mottling, creates a unique visual element for each project. Designers can choose appearance and gloss levels, ranging from a soft satin to a highly polished reflection. Today, a broad palette of color created through the use of integral color and modern stains and dyes is available, and the designs can incorporate stenciling, etching, and custom graphics. This course focuses on normal-weight concrete slabs-on-grade.
By the end of this course you will be able to identify and discuss proper and safe joint sealant application procedures. You will also be able to recognize and understand the different causes for common sealant problems. Finally, you will also be able to compare and contrast different sealant types.
