Optimization of ultra-high-performance concrete by the use of a packing model

The concept of high packing density has been recently rediscovered, as a key for obtaining ultra-high-performance cementitious materials. First, this paper presents two models allowing to predict the packing density of a particle mix. These models are derived from the Mooney's suspension viscosity model. At a second step, considerations on the parameter to be maximized during the mix-design process are presented. Reference is made to the Maximum...
