“…Therefore, this model was improved considering the virtual density theory and a new model known as solid suspension model (SSM) was developed (Larrard and Sedran 1994). Afterwards, based on the compaction index concept and virtual packing density, the compressible packing model (CPM) for the mixture design of UHPC was proposed (Larrard and Sedran 2002). Yu et al (2014) optimized the mixture ingredients of UHPC using a modified Andreasen and Andersen model with various distribution modules.…”

In this study, an extensive literature review has been conducted on the material characterization of UHPC and its potential for large-scale field applicability. The successful production of ultra-high performance concrete (UHPC) depends on its material ingredients and mixture proportioning, which leads to denser and relatively more homogenous particle packing. A database was compiled from various research and field studies around the world on the mechanical and durability performance of UHPC. It is shown that UHPC provides a viable and long-term solution for improved sustainable construction owing to its ultrahigh strength properties, improved fatigue behavior and very low porosity, leading to excellent resistance against aggressive environments. The literature review revealed that the curing regimes and fiber dosage are the main factors that control the mechanical and durability properties of UHPC. Currently, the applications of UHPC in construction are very limited due to its higher initial cost, lack of contractor experience and the absence of widely accepted design provisions. However, sustained research progress in producing UHPC using locally available materials under normal curing conditions should reduce its material cost. Current challenges regarding the implementation of UHPC in full-scale structures are highlighted. This study strives to assist engineers, consultants, contractors and other construction industry stakeholders to better understand the unique characteristics and capabilities of UHPC, which should demystify this resilient and sustainable construction material.

“…Based on the properties of multimodal, discretely sized particles, De Larrard and Sedran [36,37] postulated different approaches to design concrete: the Linear Packing Density Model (LPDM), Solid Suspension Model (SSM) and Compressive Packing Model (CPM). Furthermore, Fennis et al [38] developed a concrete mix design method based on the concepts of De Larrard and Sedran [36,37]. However, all these design methods are based on the packing fraction of individual solid components (cement, sand, etc.)…”

“…The last equation should link the compressive strength and the proportions of the paste. In the literature, one can find many relations linking proportions and strength, for example, a modified Feret relation [23]. In our study, it was decided to apply Bolomey's equation [24]: …”

The concrete industry is an important source of CO 2 gas emissions. The cement used in the design of concrete is the result of a chemical process linked to the decarbonation of limestone conducted at high temperature and results in a significant release of carbon dioxide. Under the project EcoBéton (Green concrete) funded by the French National Research Agency (ANR), concrete mixtures have been designed with a low cement quantity, by replacing cement by mineral additions i.e., blast-furnace slag, fly ash or limestone fillers. Replacement of cement by other materials at high percentages generally lowers the early age strength of the resulting concrete. To cope with this problem, an optimisation method for mix design of concrete using Bolomey's law has been used. Following the encouraging results obtained from mortar, a series of tests on concretes with various substitution percentages were carried out to validate the optimisation method.
