Development of Thin-Wall Element Construction by Utilization of Nano-SiO2 Particles



In this study, the application of high performance mortar in order to cast thin ferrocement element by the use of nano-silica particles is investigated. Variable parameters consist of the amount of nano-silica particles respect to cement quantity in the ordinary Portland cement mortar (1%, 2%, and 3%) and super-plasticizer used to achieve similar workability. To compare the mixes, mortars with high and similar workability were casted which guarantee the identical pomp-ability of ferrocement to cast the elements. In addition, regarding to examining the micro-structure and mechanical properties of recycled concrete, Scanning Electron Microscopy (SEM) test and compressive strength have been applied respectively.
