A Study and Comparison on Compressive Strength, Tensile Strengthand Elastic Modulus of Confined Self-Compacting Concrete (SCC) byPolymeric Material GFRP Investigation of Self Compacting ConcreteConfined

Self-compacting concrete does not have problems associated with conventional concrete construction, including the inabilityto fill the mold, inability to completely surround the reinforcement in reinforced concrete structures, vibration equipmentperformance and noise caused by their. Using reinforced polymer sheets became conventional from mid-1980s and replaced ofpolymer sheets in order to overcome the disadvantages caused by reinforced with steel sheets. Unlike steel sheets, it was notbeing under corrosive agents and it is resistant against harmful effects caused by acids, salts and other environment corrosive.Many of the proposed relationships for estimating the compressive strength of confined concrete and similar strain have beenobtained based on the experimental results and they possess a lot of diversity, this shows the behavioral complexity of confinedconcrete and its dependence on the various parameters. In this paper, experimental results are presented concerning the behaviorof self-compacting concrete enclosed as single-layer and double-layer by polymeric material GFRP. Cylindrical specimens ofself-compacting concrete are used with dimensions of 150 × 300 and 100 × 200 mm for testing compressive strength, tensilestrength and modulus of elasticity.
