Study of the Permeability of Roller-Compacted Concrete in Transportation Projects

Roller-compacted concrete (RCC) is defined as a dry concrete with zero slump. In recent years, the use of RCC in the construction of dams and road pavements has gained widespread acceptance. This trend is attributed to both technical and economic justifications, leading to its global adoption. However, concerns regarding fluid seepage in roller-compacted concrete dams have always been a critical consideration for designers. Therefore, measuring the permeability of concrete in dams is essential to determine the extent of fluid seepage and to provide a criterion for evaluating the durability of the concrete. The main objective of this research is to investigate the effects of various parameters on the permeability of roller-compacted concrete, including mix design, age of the mixtures, cement content, amount of cementitious materials, water-to-cement ratio, percentage replacement of pozzolan (clash), maximum aggregate size, and the amount of silica fume.
