       Moisture in concrete slabs can be a big problem on a project, especially when flooring is installed. Even when epoxies are applied over the slab to protect vinyl floors and carpet from moisture, buckling and mold can occur.

      After receiving a few questions regarding my last blog post, “Fly Ash and Sustainable Concrete,” I determined a review of the different types of supplemental cementitious materials (SCMs) would be a good idea.  However, getting half-way though writing the post, I realized, without a basic understanding of cement, it’s hard to understand why we would want to replace it. That in mind, let’s start with the basics of cement, and cement hydration, and then go into a series of posts where I will discuss briefly the different cementing materials used in concrete, and the benefits and drawbacks of ...

      A "concrete" solution to moisture-related flooring problems. Every year, moisture-related flooring problems (and the disputes that follow) add hundreds of millions of dollars to project costs. Scores of topical approaches have been introduced to try to mitigate the effects of high moisture levels in concrete slabs. These treatments, however, can add significant costs to a project, be disruptive to apply, and, to date, have not proven to be 100% effective.

      Fly Ash and Sustainable Concrete   If you’re trying to gauge industry interest in green concrete technology, you actually don’t have to go farther than LinkedIn®. It didn’t take long to find a discussion on the American Concrete Institute’s® page entitled “Difficulties attaining compressive strength using fly ash in concrete mix when 28-day strength is specified?”.  There were a number of interesting contributions made to this discussion that could explain why the 28-day strengths were not achieved, but to take a more holistic approach, let’s look at the three primary reasons why fly ash is used in concrete: for reduced costs ...

      The future of colored concrete is green, consistent, high-performing and warranted. The future of colored concrete is green, consistent, high-performing and warranted. This can be accomplished by environmentally-friendly color mixes that reduce the carbon footprint of concrete structures, contribute toward LEED® qualification, conserve natural resources and reduce pollutants for all types of decorative concrete applications.

      Comment "I look forward to seeing your presentation at the Concrete Sustainability Conference in Boston" - Ryan Henkensiefken (USC Technologies)

      Sustainable Design - Low Carbon Concrete Mixes The Tennant Avenue Bridge is a typical overpass that one may see throughout the United States. Its construction wasn’t unique; that is, no changes were made to its construction schedule to compensate for the reduced carbon footprint. The carbon footprint was reduced 25% compared to traditional mixes and may well have been further reduced. The specifications by which the concrete mixes were allowed to be used represent a dramatic change that provides a glimpse into the future sustainable design and construction of the infrastructure.

      Sustainable concrete design in the green revolution: Producer's Perspective More owners and major developers are insisting on sustainable building designs and construction practices. This is a major reason why the sustainable market is one of the fastest growing segments in the construction industry. Fortunately, many technologies exist today to meet this demand; however, the major hindrance in today's construction environment lies in the lack of flexibility in design codes and specifications. Many specifications limit the concrete producer’s ability to achieve a truly sustainable concrete by prescribing mixture proportions rather than setting performance criteria. In the past, there has been a push in the industry to move from ... (Read Full Article)
