While significant advances have been made in concrete materials and in concrete structures over the last decade, research in materials and in structural engineering are often carried out separately. As a result, opportunities in major leaps in structural performance may be missed, or research emphasis in materials development may be misguided. This paper introduces the concept of integrated str...

Textile industry has become an essential part of modern society, and waste production is an inevitable outcome of the developmental activities. Present paper outlines a direct approach toward a real problem of managing spinney waste fibers generated during textile industry. Simultaneously, shortage in landfill disposal space is another trouble associated with dumping of these hazardous wastes. ...

This paper describes analytical methods that can be used to determine the deflections and stresses in highly compliant graphite-reinforced cementitious composites. It is demonstrated that the standard transform section method fails to provide accurate results when the elastic modulus ratio exceeds 20. So an alternate approach is formulated by using the rule of mixtures to determine a set of eff...

High performance fiber reinforced cementitious composites have made major advances in recent years, to the point where they are being adopted in building and bridge constructions. The most significant advantage of HPFRCC over conventional concrete is their high tensile ductility. However, the tensile strain capacity has been observed to vary, most likely as a result of the variability of the mi...

Abstract: The Quasi-static mechanical properties of hybrid fiber (steel fiber and Polyvinyl alcohol (PVA) fiber) reinforced cementitious composites (HFRCC(SP)) were investigated by compressive and tensile experiments. The compressive strength, peak strain, elastic modulus and tensile strength are studied as compared with that of engineered cementitious composite (ECC). Study results indicate th...

Abstract Polymer-impregnated carbon fabric is used as an alternative to metallic reinforcement bars in cementitious materials, which then termed textile-reinforced concrete (TRC). In this study, the bond strength between cement-based matrix and was enhanced by decorating polymer (an epoxy) coating with hydrophilic micron-size particles (cement or silica) nanocarbons (functionalized nanotubes gr...

The application of fibers to reinforce cementitious materials is a well-known subject. At first, asbestos fibers are used in industrial process to produce fiber reinforced cement sheets. Thereafter, various types of synthetic fibers are produced and used as asbestos substitutes. The aim of the present work is to evaluate the effect of synthetic fibers on the flexural behavior of cementitious co...

Fiber-reinforced cementitious matrix (FRCM) and steel-reinforced grout (SRG) have been increasingly applied as externally bonded reinforcement to masonry members in the last few years. Unlike fiber-reinforced polymer (FRP), FRCM SRG good performance when exposed (relatively) high temperature compatibility with inorganic substrates, they can be wet surfaces at (reasonably) low temperatures. Alth...

in spite of the fact that cementitious and concrete materials are mainly used on a large scale and inhuge quantities for roads, dams, bridges and building constructions, the mechanical behavior of thesematerials depends to a great extend on structural elements and phenomena which are effective on amicro and nanoscale. although this is well known by researchers, material producers and engineersf...

Cementitious composites such as concrete pavements are susceptible to different damage modes, which are primarily caused by repeated loading and long-term deterioration. There is even greater concern that damage could worsen and occur more frequently with the use of heavier vehicles or new aircraft carrying greater payloads. Thus, the objective of this research is to engineer cementitious compo...
