Explosive spalling is generally considered to be caused by concrete fracturing due to the interaction of (a) the pore pressure induced by moisture transport and vaporization and (b) the stress induced by thermal gradients and external loads. In order to investigate the first point, a special setup has been designed and an experimental campaign has been recently launched at the Politecnico di Milano, regarding ten different concrete mixes, characterized by different compressive strength, aggregate and fiber types.
