The new American Concrete Institute (ACI) 301-20, Specifications for Concrete Construction, provides the latest construction practices and concrete-related material information necessary for today’s contract documents.
Many of the largest retailers have been specifying, or soon will be specifying, certified individuals on new construction projects. It is worthwhile for owners and specifiers on projects of all types to follow their lead. Good quality control can result in significant cost and time savings. Therefore, it is in every owner’s interest to promote quality and require contractors who maintain the highest industry standards that are confirmed by certification, such as the ones offered by the American Concrete Institute (ACI).
Building for durability of concrete infrastructure in severe environments is an ongoing challenge for contractors and engineers. Using a performance-related design method offers a good strategy for extending service life by taking a long-term approach to mitigating corrosion.
Over the past few years, there has been considerable discussion on concrete construction and its impact on global warming. The authors argue concrete is, in fact, a relatively low-impact material, not only due to its durability, long service life, and recyclability, but also because of increasing investments in more sustainable manufacturing technologies.
Research is ongoing to advance precast concrete insulated wall panel technology by developing materials and design to double its thermal performance and reduce weight by half without increasing costs. The main goal of this project is to promote passive envelope technologies for improving energy efficiency in new construction.
