Interfacial transition zone in reactive powder concretes (RPC) cured under various hydrothermal conditions

Archives of Civil Engineering, 2020
Reactive powder concrete (RPC), due to its characteristic composition with reduced water quantity, often below a stoichiometric ratio, the addition of pozzolana usually close to or above 20% of the weight of cement and a significantly reduced inclusion rate compared to normal or high performance concrete, has a different nature of the interfacial ...
