Providing a framework for optimizing a mixing design of reactive powder concrete (RPC)

Suitable distribution of particles and the presence of hydration lead to the improved compressive performance and optimum (even reduced) cost in the production of reactive powder concrete (RPC). This study was conducted to obtain a better understanding of RPC and analyze the behavior of modified RPC...
