Moisture transport and drying shrinkage properties of steel–fibre-reinforced-concrete
Highlights Moisture transport and shrinkage properties are obtained for CC, RCC and SFRC. Nonlinear moisture diffusivity is determined by experiments and FE inverse analysis. Hygral contraction coefficient, or free shrinkage versus moisture loss, is derived. These values can be used to numerically predict shrinkage distress in ground slabs. Moisture diffusivity of RCC is higher than CC, RCC shrinks at a more uniform rate.
Abstract Drying shrinkage has a serious impact on the structural and durability performance of concrete pavements. Shrinkage strain development and distress can only be fully understood by knowing the moisture transport and free shrinkage properties of concrete. This paper uses experiments and FE inverse analysis to determine these properties for conventional concrete (CC) and RCC reinforced with recycled-steel–fibres from tyres. Moisture diffusivity versus moisture content and a relationship between free shrinkage and moisture loss are derived. These values can be used to predict shrinkage strains and stresses in road pavements and other ground restrained slabs.
