Fracture Toughness of Cement Paste and Mortars

  title={Fracture Toughness of Cement Paste and Mortars},
  author={John Hartley Brown and Cheryl Susan Pomeroy},
Abstract The effective fracture toughness of a range of cement pastes and mortars have been measured using both a notched beam and a doublt cantilever beam method. The influence of size and quality of aggregate on the effective toughness has been studied as the cracks advance. The observed values of fracture toughness are dependent on crack velocity.
