---------------------------------------------------------------------***--------------------------------------------------------------------Abstract Concrete is the most widely utilized “manmade” material globally for construction in many developing countries in all types of civil engineering works. Also, concrete is an environmental friendly material and in areas of growing environment – relat...

This study investigates the mechanical behavior of steel fiber-reinforced concrete (SFRC) beams internally reinforced with steel bars and externally bonded with carbon fiber-reinforced polymer (CFRP) sheets fixed by adhesive and hybrid jointing techniques. In particular, attention is paid to the load resistance and failure modes of composite beams. The steel fibers were used to avoiding the rip...

A new generation of concrete highway bridges has recently been built in Canada using new design concepts and advanced materials for reinforcing and prestressing concrete . This paper describes briefly the design and construction of three bridges. The first smart concrete highway bridge (Centre Street, Beddington Bridge, Calgary, Alberta) is prestressed by carbon fiber reinforced plastic (CFRP) ...

In recent years, the construction industry has seen a significant rise in the use of natural fibers, for producing building materials. Research has shown that treated hemp fiberreinforced concrete (THFRC) can provide a low-cost building material for residential and low-rise buildings, while achieving sustainable construction and meeting future environmental targets. This study involved enhancin...

This study concerns improvement of flexural stiffness/strength of concrete members reinforced with externally bonded, aluminum-glass fiber composite (AGC) beams. An experimental program, consisting of seven reinforced concrete slabs and seven reinforced concrete beams strengthened in flexure with AGC beams, was initiated under four-point bending in order to evaluate three parameters: the cross-...

To increase the applications of Natural Rubber Latex Modified Fiber Reinforced HighPerformance-Concrete (NRLMFRHPC) in India, greater understanding of NRLMFRHPC produced with locally available materials such as cement , Fine aggregates , coarse aggregates, Metakaolin and Crimped Steel fibers is essential. In the present investigation, NRLMFRHPC has been produced with locally available aggregate...
