The impact resistance and mechanical properties of the reinforced self-compacting concrete incorporating recycled CFRP fiber with different lengths and dosages

Regarding the obtained large experimental database, an analytical analysis was executed by using linear regression analysis to correlate the impact and mechanical properties of the reinforced self-compacting concrete, considering different contents and lengths of recycled carbon fiber. The results showed that increasing recycled carbon fiber volume fraction and length enhances mechanical properties and impact resistance of the reinforced mix compositions, while reduces the workability.
