Concrete temperature monitoring becomes more critical in cold weather as low temperatures decrease the rate of strength development affecting the durability of the structure. For this reason, accurate and consistent temperature readings of concrete elements are important so that the quality of the structure is optimized.
Specifying resinous flooring systems involves crunching numerous performance data points, such as compressive strength and abrasion resistance, to select the optimal flooring system for a given environment. A major goof in picking a system could mean years of lost durability.
The four-storey North Bay Courthouse building in Ontario was retrofitted with a new lateral force-resisting system (LFRS). The interior steel framing and slab connections were structurally strengthened to transfer seismic loading to 13 full-height, reinforced precast concrete shear walls around the building perimeter. Further, cracked masonry joints were repointed, damaged masonry units were replaced, and an elastomeric coating was applied over the entire wall surface.
Self-consolidating concrete (SCC) is designed to flow and synthesize on its own. Even though the technology has advanced, it retains an air of mystery. This article provides an overview of SCC and explains its many benefits, design, chemistry, plastic performance, production, specification, testing and certification, and construction best practices.
Most floorcovering failures result from design mistakes, lack of groundwater barriers, and placement of the material before concrete has dried to safe levels. Therefore, all members of the project team must collaborate at every stage, such as the design, placement, curing, and relative humidity (RH) testing of the concrete.
Traditionally, nondestructive testing (NDT) of concrete refers to testing, inspecting, or evaluating concrete materials or components without damaging or destroying the serviceability of the structure or materials. These tests have usually been performed on structures that have been in service for some time, but present-day technology allows the use of NDT methods during the construction of new concrete elements as well.
Polished concrete is one of the most widely utilized floor systems. However, a successful outcome with this material in new construction is still unpredictable. It can be difficult to translate the expectations of building owners and designers into results, particularly with the overall ‘look’ of a polished floor and/or its durability.
Energy and thermal performance requirements are growing and playing an increasingly significant role in building codes throughout North America. However, understanding and meeting these requirements has also become complex for designers. At the same time, it is clear important decisions regarding basic enclosure assembly design and window area need to be made early in the project to achieve the most cost-effective, energy-efficient, and comfortable building.
The Canadian Precast/Prestressed Concrete Institute (CPCI) and the Canadian Concrete Pipe and Precast Association (CCPPA) have announced a new certification program which will take the place of two existing ones.
