The Lehigh cement brand includes various types of gray portland cements which meet or exceed ASTM C150. These quality cements are available for shipment in bulk quantities, or packaged in bags, as described below:
Type I
A general-purpose portland cement suitable for all uses where special properties of other types are not required; uses include pavements, sidewalks, reinforced concrete buildings, bridges, railway structures, tanks, reservoirs, culverts, water pipe and masonry units. Available in 42.6 kg (94-lb.) bags, and in bulk quantities.
Type IA AIR- ENTRAINING

Type I/II
This portland cement meets ASTM C 150 for either Type I or Type II requirements. Available in 42.6 kg (94-lb.) bags, and in bulk quantities.
Type II SULFATE RESISTANT
Type II portland cement offers moderate heat of hydration and sulfate resistance, for applications where sulfates in ground waters and/or soils are higher than normal, or in mass concrete work where heat of hydration is a concern. Available in 42.6 kg (94-lb.) bags, and in bulk quantities.
TYPE III HIGH EARLY STRENGTH
Type III portland cement provides high early strengths during concrete curing, allowing forms to be stripped earlier or the structure to be put into service quickly. Available in 42.6 kg (94-lb.) bags, and in bulk quantities.
TYPE V HIGH SULFATE RESISTANT
Type V portland cement is principally used where soils or ground waters have high sulfate contents. Available in 42.6 kg. (94-lb.) bags, and in bulk quantities
