Reinforced Concrete Strengthening By Using Geo Textile Reinforcement for Foundations and Slabs
Journal Title: International Journal of Environment, Ecology, Family and Urban Studies (IJEEFUS) - Year 2017, Vol 7, Issue 3
Abstract
This research aims to discover experimentally, the punching shear behavior of reinforced concrete slabs strengthening, by using geogrid mesh with different percentage of steel reinforcement ratio (ρ), where the main parameter which adopted in the experimental program are the presence of geogrid mesh, steel reinforcement ratio and concrete compressive strength, where three type of concrete were utilized; normal strength concrete (NSC), high strength concrete (HSC) and reactive powder concrete (RPC). Fifteen slabs are made, five of each type of concrete in the same group, one of the slabs is without geogrid mesh and four strengthening with the geogrid, and the other four are different in steel reinforcement ratio (ρ). The dimensions of slabs in the present work are (850x450x70) mm in length, width and thickness. The experimental results indicate that, in the presence of geogrid, there is an increase in ultimate load. This increase differs with the differentiator of steel reinforcement ratio (ρ), continuously, until steel reinforcement ratio (ρ) is reduced to (0.0026).
