Alkali-Silica Reaction (ASR) is one of the most damaging forms of chemical deterioration in concrete structures, causing progressive cracking and loss of structural integrity when reactive silica in aggregate reacts with alkalis in cement paste. Western Geotechnical Laboratory Services (WGLS) provides a comprehensive range of accredited Potential Alkali Reactivity testing to Australian Standards and Main Roads WA specifications, including the ASR Mortar Bar method (AS 1141.60.1), the ASR Prism method (AS 1141.60.2), and the ASR Mortar Bar MRWA Method (WA 624.1). These tests allow concrete producers, structural engineers, and materials specifiers to identify potentially reactive aggregate sources before use in concrete construction, safeguarding the long-term performance and durability of infrastructure across Western Australia.
