Wear resistance is required to provide abrasion and erosion protection in order to prolong the service life of concrete. An integral hardening admixture is critical for a functional, superior and long-lasting structure. This educational unit examines exactly how concrete hardening technologies work, differing features and benefits, so the best abrasion and erosion resistant methods can be specified for each project.
This course will provide an overview of the history and role of welded wire reinforcement in concrete construction. It will help architects and designers understand the benefits of WWR in creating high-performance buildings and will explore best practices in specifying WWR to realize cost and time savings in construction that ultimately benefit the owner and all project stakeholders.
In addition to performance, budget and aesthetics, design professionals are now being asked to evaluate the environmental burdens of their design choices. Measuring the impacts of buildings, assemblies and products can be complex. Every design decision, from material and product selection to envelope design and construction can have an impact on the environment and the methods used to evaluate those decisions are still not widely understood. This article will address critical issues the design professional should consider as he/she evaluates the environmental impacts of building materials to maximize performance and deliver lasting value.
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.
Once the concrete pour begins, there is no turning back. Each step from pouring to finishing will determine the success or failure of the placement. This paper explains the steps necessary to create a smooth, strong finished product.
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.
