Abstract: This paper investigates the transport properties altered by crack-induced damage of two structural concretes [ordinary portland cement concrete (OPC) and high-volume fly ash concrete (HVFC)]. The crack-induced damage is ...

Abstract: This paper establishes a comprehensive modeling for permeability of porous solids incorporating cracks with clustering extent ranging from nonoverlapping to percolation. The geometry of cracks is characterized through the ...

Abstract: The present study investigates the mechanisms of moisture transport in porous materials. For partially saturated porous materials, moisture transport relies on both the Darcian flow by capillary pressure gradient and the ...

Abstract: The maintenance of a considerable number of concrete structures the durability and serviceability of which are endangered by the alkali–silica reaction (ASR) requires a quantitative structural evaluation and prediction, ...

Abstract: This paper introduces the durability design of concrete structures in the Hong Kong–Zhuhai–Macau project for a working life of 120 years. The environmental actions are analyzed and the deterioration processes for the ...

Abstract: This study presents the electrical resistivity responses of saturated cement pastes undergoing cyclic freeze-thaw (F-T) action. An ordinary cement paste (OPC) and a blended paste (CS) containing ground granulated blast-furnace ...

Abstract: Corrosion of reinforced concrete is one of the major deterioration mechanisms that results in premature failure of the reinforced concrete structures. In practice, concrete crack width is one of the most important criteria ...
