Definitions

  • a cement composition comprising hydraulic cement and .5 to 3% by weight of the hydraulic cement of a naphthalene sulfonate condensate wherein the maximum moisture content of the composition is 8% by weight.
  • the invention also provides a method of making a concrete article by introducing the cement composition into a mould, applying pressure and vibration to the cement composition thereby forming a concrete article and removing the concrete article from the mould after the short time.
  • the glass aggregate was obtained from a glass recycling company who also cleaned the glass.
  • the grading of the recycled glass is shown in Table 2.
