Abstract:

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

Abstract:

Ferrocement and more generally laminated cement based composites are in a state of revival worldwide. Looking back and looking ahead, this paper focuses on three aspects of development that are at the basis of the current revival of ferrocement: 1)the application side, where some new limits and new daring ideas were demonstrated; 2) the professional side, particularly the activities of the International Ferrocement Society and the publication of the first Ferrocement Model Code, and 3) the technical side, where high performance fiber reinforced polymeric (FRP) meshes are introduced either alone or in combination with fibers or micro-fibers leading to hybrid composites with improved performance and reduced cost. Prospects for the near future are also discussed.

Abstract:

The United States is a country known for its wasteful use of natural resources. Effort so correct the results of past transgressions as well as to balance economic development against legitimate concerns of conservation are pervading almost all aspects of life, including the construction industry. Concrete, being the most widely used material worldwide, is a natural target for greenhouse gases and energy user. Recent research has led to the point where substituted partially fror cement, such as fly ash and ground granulated blast furnace slag. Also other recycled materials are finding increased application in concrete produciton. For example, recycled concrete has been used successfully in numerous projects, and crushed waste glass is now available as a valuable source of aggregate, since the problem of alkali-silicate reaction has been solved. The key to commercial success is beneficiation, ie.e. the targeted utilizaion of specific properties of the recycled material, which adds value to the end product.

Abstract:

An intoductory construction materials course was developed for first year civil and environmental engineering students at the University of Maine. Because it is typically the first engineering course in which most civil engineering students enroll, the course also serves as an introduction to principles of engineering aalysis and desing. We have adopted a materials science approach in our coverage of construction materials. That is, we emphasize how material properties are a function of their microstructure, and that we control microstructure through processing. We have found concrete to be an ideal material with which to illustrate this concept. Students are easily able to observe the processing-microstructure-properties links through laboratory and homework exercises in concrete mix design and testing. In the broader context we have found materials in general, and concrete in particular, to be excellent model topics for intoducing the general topics of engineering analysis and design.
