Hot-dip galvanizing has been applied to reinforcing steel in concrete used for precast panels, barriers, and bridge decks since the early 1970s. While new technologies have surfaced in decades past, none have matched the performance or economic savings that galvanized reinforcing steel has delivered.
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.
The East Deicing Apron, a new deicing pad at the Calgary International Airport (YYC), has been built with reduced-carbon concrete. The first airplanes started using the facility just weeks ago.
Climate change poses challenges for building professionals tasked with the job of protecting structures from water damage. By becoming a part of the concrete, crystalline admixtures remove the need for a waterproofing membrane.
Sustainable structures must balance the environmental footprint, service life, social aspects, and economic factors. As modern society shifts to a circular, carbon-neutral built environment, concrete continues to deliver ‘best-in-class’ performance as a building material.
The American Concrete Institute (ACI) published ACI 318-19, Building Code Requirements for Structural Concrete, in July. ACI 318 presents requirements for design and construction of structural concrete that are necessary to ensure public health and safety. It is addressed to the engineer or the building official who is responsible for the contract documents.
Vancouver-based Revery Architecture has designed Simon Fraser University’s (SFU’s) new state-of-the-art engineering building in Surrey, B.C. The academic research facility focuses on clean technology and sustainable energy solutions.
