1.1 Background Fibre Reinforced Polymers (FRP’s) have seen active use for strengthening applications in construction since the late 1980’s. They are now securely placed to replace the ageing technologies used in the commonly termed, ‘traditional methods’ of strengthening, which have customarily resulted in an increased cross-section size with the provision of additional reinforced concrete, or ...

With the growing population and density in metropolitan areas, higher tendency to live in high-rise buildings, and increasing demand for parking lots, it seems necessary to excavate soil to construct underground spaces. During excavation work, as the height of the wall increases, special care should be taken to the wall stabilization to avoid any consequent damage including extensive property d...

Spending costs in construction of road pavements has turned this subject into one of the significant points in transportation infrastructure of countries. Concrete slabs consider as a paving method with ability of reducing the rehabilitation needs. Therefore, to manage costs and optimize the thickness of concrete pavements, recognizing the amount of determinative factors’ influence will be requ...

semiconducting carbon nanofibers (cnf) are prepared from three different sources, i.e., acetylene, ethanol, and cotton by the chemical vapor deposition (cvd) process. these fibers are having rich elastic, engineering and conductivity properties. fresh self-compacting concrete (scc) flows into place and around obstructions under its own weight to fill the formwork completely and self-compact, wi...

Abstract In recent years, the growing need for reducing non-structural damage after earthquakes has stimulated a dedicated effort to develop innovative types of fasteners anchoring components (NSCs) reinforced concrete (RC) host-structures. To contribute such need, and building on previous research, this paper presents results series uni-directional shake-table tests simulated NSCs anchored via...

Civil construction is essential for the world economy and largest generator of demolition waste (CDW), mainly due to a lack planning, technological control, restoration execution, among other factors. While efforts are made minimize this generation, one possible application CDW its incorporation into Portland cement-based materials as recycled aggregates, in partial or total replacement natural...
