Carbonization test and orthogonal polynomial regression analysis of steel fiber reclaimed concrete

Heliyon
To enhance the carbonation resistance of reclaimed concrete, several key factors affecting its performance were investigated. An orthogonal array L16(4³ × 2⁶) was employed to design the carbonation tests for steel fiber (SF) reinforced concrete.
