Paper Title:
Experimental Study on Stress-Strain Relationship of New-Old Concrete
  Abstract

In this paper, full-range compression tests were conducted on prisms of Old concrete, New-Old concrete and High-Performance Rapid Repair Concrete (HPRRC) prisms The complete stress-strain curve of HPRRC incorporating PFAC (pulverized fly ash composite), Old concrete and New-Old concrete were obtained and compared with each other. The essential uniform deformation capacity of three kinds of concrete was verified with the experimental results. At the same time, the unified numerical expressions of the compressive complete stress-strain curves of the three kinds of concrete are put forward. The theoretical curves from calculation are in good agreement with the experimental curves.
