In order to reuse concrete forms, contractors want to remove them as quickly as possible. When approved by the building official and in conformity with project specifications, quicker, in-place test methods may be used:
  • Cast-in place cylinder strength (ASTM C 873)
  • Penetration resistance (ASTM C 803)
  • Pullout strength (ASTM C 900)
  • Maturity factor measurements (ASTM C 1074)
