Abstract:
Even at a level of less than 0.5% by mass of aggregate, pyrrhotite can cause extensive cracking and crumbling of concrete. Because such type of deterioration is rather new, a proper testing protocol to forecast potential damage in concrete is needed. The article discusses important factors that should be considered when developing such performance-based test protocol.
