Dry concrete is defined as the fresh mixture having no flowability with a very small slump value. Dry concrete technology has been widely used in many engineering fields by virtue of its remarkable advantages. Dry ultra-high performance concrete (DUHPC), developed and studied in this thesis, is a promising building material with better mechanical performance and excellent eco-friendly benefit.Chapter 1 introduces the background, application and advantages of dry concrete, and presents the motivation and outline of this study.Chapter 2 provides a detailed literature review of the representative dry concrete mixtures named roller-compacted concrete (RCC) and dry-cast concrete (DCC). It was shown that the preparation method and raw material played the dominant role in the performance of dry concrete. Dynamic material tests revealed that dry concrete was a strain rate sensitive material.In Chapter 3, the mechanical performance of steel fibre-reinforced DUHPC (FRDUHPC) was experimentally investigated. It was concluded that the inclusion of steel fibres contributed more positive impact to the flexural performance, and 50 ℃ moist/steam curing was suggested considering the early/long-term strength.The influences of multiscale mono/hybrid steel fibre reinforcements on the static mechanical performance were studied in Chapter 4. The results showed that the mixtures with hybrid 10-/13-mm fibres as well as hybrid 6-/10-/13-mm ones were suggested to be used for DUHPC structures/units that were mainly subjected to static loads. The proposed multivariate regression models could well predict both the flexural and split-tensile properties.Chapter 5 explores the feasibility of introducing the recycled wastes into DUHPC. The findings illustrated that the contribution of fly ash to the strength was evidently increased owing to the moist/steam curing. For rubberized FR-DUHPC, the use of finer rubber particles caused the most evident decrease in concrete properties at all ages, whereas the adverse effect was less serious on flexural strength. The developed lightweight dry concrete can be used in eco-friendly constructions.Chapter 6 evaluates the impact resistance of FR-DUHPC by conducting the lowvelocity drop-weight test. The results revealed that the impact performance was markedly improved with fibre length, but significantly deteriorated with fly ash and rubber addition. Moreover, the use of 6-mm fibres to substitute partial longer ones could not restrain the microcracks rapid development. The two-parameter Weibull distribution could well predict the failure hit number of FR-DUHPC under repeated impact.Chapter 7 summarizes the findings of this study and proposes some suggestions and ideas for the future research of DUHPC.
