The specification of structural concrete is a vital ingredient in the process of construction to ensure we achieve durable, sustainable, and serviceable infrastructure. However, the Australian heavy construction materials industry is facing a number of technical challenges in maintaining the position of concrete as a material of choice for the construction industry, and this is having an impact at the specification stage.
With increasing pressure and expectation on suppliers, specifiers, and construction companies to complete projects within difficult time frames and budgets, and without key personnel and resources, it means that specifications are not being developed to allow for continued superior performance of concrete structures. Many specifications are just repeating historic properties and benchmarks with little understanding of their purpose and potential implications. More worryingly, there are often perverse outcomes arising from this confusion.
