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 American Concrete Institute (ACI) is holding a convention in Quèbec where attendees will get a chance to collaborate on concrete codes, specifications, and standards. It will take place at the Québec City Convention Centre and Hilton Québec Hotel from March 24 to 28.
A collaborative effort has been launched between the National Research Council Canada (NRC), the Québec government, and Université Laval to find a solution to problems stemming from the presence of pyrrhotite in concrete.
CSC Ottawa is hosting a breakfast meeting on Thursday, January 17, at the Ottawa Conference and Events Centre. An overview of the Canadian Standards Association (CSA) A23.1/2-2018, Concrete Materials and Methods of Concrete Construction/Test Methods and Standard Practices for Concrete, will be presented at the meeting taking place from 7:30 to 10 a.m.
Raked joints are commonly used in masonry walls for esthetic purposes. A widespread opinion is they reduce the fire resistance of concrete masonry. However, full-scale experimental tests and numerical studies have now found the fire resistance of walls does not greatly depend on the thickness of the mortar.
The Kitchener (Ont.) city council voted seven-three against protecting the distinctive concrete façade of a former Sears building with a heritage designation. The 53-year-old building was built in the Kennedy-era international style.
