Cement Types. ASTM Specification C-150 provides standards for eight different types of Portland cement: Type I is a general-purpose cement used in a wide variety of project types, including buildings, bridges, floors, pavements, and precast concrete projects. Type IA is similar to type I but is used for projects requiring air-entrainment.
