Worldwide Acceptance
Subhead Goes Here
PLC is broadly accepted for buildings and infrastructure projects throughout the U.S. including acceptance by all 50 state departments of transportation. The key to allowing PLC on projects is to ensure specifications permit the use ASTM C595 Type IL (read as “one-ell”) cement and AASHTO M 240 Type IL (All of the technical requirements of ASTM C595 and AASHTO M 240 are the same.). In Canada, PLC is specified as CSA A3000 Type GUL (read as “G-U-L”).
​
Type IL is also permitted:
-
By codes, like ACI 318, Building Code Requirements for Structural Concrete
-
By specifications, like ACI 301, Specification for Structural Concrete
-
By standards, like ASTM C94, Specification for Ready Mixed Concrete
-
And by the AIA MasterSpec that is used by design firms to develop their specifications for private projects.
