Abstract: This paper describes an experimental investigation to assess the development of the localized damage zone in concrete tested in compression. Cylindrical specimens were loaded and unloaded at different maximum strain levels. ...

Abstract: Although the opportunity to replace prescriptive codes and specifications with those based on performance has been widely discussed, currently only limited tools are capable of providing performance-based description of ...

Abstract: In service, concrete can develop cracks or microcracks that can influence the transport of liquids and ions. This paper describes an investigation of fluid transport in concrete damaged by tensile loading or freeze–thaw ...

Abstract: This paper describes the role of lightweight synthetic particles (LSP) on the restrained shrinkage cracking behavior of mortar in sealed conditions. The free shrinkage, elastic modulus, split-tensile strength, and restrained ...

Abstract: Cracks in cementitious materials can substantially increase fluid penetration. Fiber reinforcement can reduce the crack width in cementitious materials, thereby reducing fluid transport. Substantial research has been ...

Abstract: Internal curing has emerged over the last decade as an approach to counteract the negative effects associated with self-desiccation in low water-to-cement ratio (w/c) mixtures. Specifically, much of the early research on ...

Abstract: The influence of cement fineness on early-age properties of cement-based materials is investigated using a variety of experimental techniques. Properties that are critical to the early-age performance of these materials ...

Abstract: Calcium chloride (CaCl2) from deicing salts can react chemically with calcium hydroxide [Ca(OH)2] from hydrated cement paste to form an expansive product, calcium oxychloride, that can damage concrete. This paper uses two ...
