Abstract

Recycled aggregates have gained popularity in the recent decade. In this paper, central composite design and response surface methodology as an analytical approach were implemented to determine experimental design and prepare models of concrete properties made by recycled aggregates in the lab. Three important factors were chosen: the compressive strength (fc) of parent concretes, the rate of substitution of parent concretes, and the amount of cement. In contrast, compressive strength (fc), tensile strength (ft), and water absorption of recycled concrete were considered target responses. Statistical analyses reveal that models were acceptable with R2 values. Both statistical and experimental studies represent that fc, ft, and water absorption of concrete mainly relied on fc of parent concretes. The increase in the fc of parent concretes from 19 MPa to 36 MPa led to the rise in the fc of new concretes from 27 MPa to 38 MPa. In addition, when the substitution rate changed from 8% to 92%, fc of concretes changed from 26 MPa to 30 MPa. Recycled concretes with higher strength could be generated if the fc of parent concrete is high enough, mainly because of the better bond between paste and aggregates. The optimization of multiple responses reveals that a high percentage of parent concretes with high fc could be used in concrete mixtures without a considerable fall in mechanical properties.

Modeling and Optimizing Recycled Concrete Properties Using Central Composite Design: The Impact of Parent Concrete

Highlights

  • The impact of parent concrete on compressive strength, tensile strength, and water absorption of new concretes is examined.
  • Parent concretes with high compressive strength can be replaced with natural aggregates at high percentages.
  • The modeling and optimization reveals that substituting high percentages of RCA in concrete is possible.
  • The introduction of waste glass as fine aggregates can reduce the water absorption of recycled concretes.
  • The high fc of parent concretes could result in higher fc and ft of new concretes.
