The impact resistance and mechanical properties of reinforced self-compacting concrete with recycled glass fibre reinforced polymers

Abstract

Experimental and statistical analyses are represented considering the impact resistance and mechanical properties of self-compacting concrete reinforced with recycled Glass Fibre Reinforced Polymers (GFRP). Specimens were reinforced with recycled GFRP in three groups, including 0.25%, 0.75%, and 1.25% of fibre volume fractions. An extensive experimental program including two hundred and fifty two specimens were prepared and tested to characterize the impact resistance and mechanical properties of the reinforced self-compacting concrete with glass fibre reinforced polymers. Scanning Electron Microscope images were used to perceive the failure mechanism of recycled glass fibre in the matrix. Then, the relatively large and reliable collected data from the experimental tests was used to start statistical and analytical analysis.The results showed that adding recycled glass fibre reinforced polymers results in improving the impact resistance and mechanical properties of the reinforced self-compacting concrete with glass fibre reinforced polymers. Moreover, the statistical data analysis revealed that the impact resistance and mechanical properties of reinforced self-compacting concrete follow a normal distribution. Furthermore, some equations were developed to correlate the impact resistance of the reinforced self-compacting specimens to the mechanical properties with high values of coefficient of determination.
