Synopsis: This article reviews the recent advances in the research of Engineered Cementitious Composites (ECC), a class of microstructurally tailored fiber reinforced cementitious composites. The design basis, the processing routes, and some ECC performance characteristics in structural applications are highlighted. This article is dedicated to Professor Surendra Shah, in honor of his seminal contributions to research and education in advanced cementitious materials over the last several decades.

Steel reinforced concrete is extensively used in construction because of its durability and cost advantages over other structural materials. However, due to aggressive use of deicing salts, or marine salt exposure, often coupled with high ambient temperatures, premature corrosion of embedded reinforcement occurs. The economic costs of corrosion of steel in concrete are substantial, and represent a major drain of infrastructure resources. This paper addresses the use of improved concrete designs to control corrosion of steel in concrete. The designs incorporate the use of low permeability concrete, corrosion inhibiting admixtures, reduced shrinkage and increased toughness with fiber reinforcement. This holistic approach to the concrete design demonstrates a lower life cycle cost.

Synopsis: Use of high strength composites for repair and rehabilitation of bridges and parking decks is steadily increasing. Since these structures are subjected to fatigue loading, the performance of strengthened beams under this type of loading needs to be evaluated. An analytical procedure that incorporates cyclic creep of concrete and degradation of flexural stiffness is presented. The method is verified by computing cycle dependent deflections and comparing them with experimental results. The results presented in this paper also provide a summary of an experimental investigation, in which reinforced concrete beams were strengthened with glass fabrics (sheets) and subjected to fatigue loading. The comparison shows that the analytical model provides reasonably accurate prediction of deflections, for both reinforced beams and reinforced concrete beams reinforced with composites. Although Glass fiber composites were used for the evaluation, the model is also applicable to other types of fibers.

The paper reviews the useful information produced during the field investigations performed during this study that can be useful for the understanding of newly constructed pavement behavior. The results are summarized, and their analysis is based on such factors as temperature effect, varying properties according to concrete age and the frictional forces between the JCPC (jointed plain concrete pavements) and its underlying layers. The results of the study can be used to help control the locations of joint cracking and crack widths of early-age concrete pavements.
