Mechanical Properties of Sprayed SFRC

摘要

Uniaxial tensile and compressive tests were conducted on sprayed SFRC with servo-controlled testing machines to obtain complete stress-strain curves, and to find out the relationship between residual strength and contents of steel fibers. Volume fraction of steel fiber was chosen to be 0, 0. 5, 1. 0, 1. 5%. Considering anisotropy of sprayed SFRC, two types of cylindrical specimens were made boring parallel and normal to the sprayed plane. Finally, a SFRC sprayed 20 years ago was tested under uniaxial tension and compression to certify its durability.
