Type I is a general purpose portland cement suitable for all uses where the special
properties of other types are not required. It is used where cement or concrete is
not subject to specific exposures, such as sulfate attack from soil or water, or to an
objectionable temperature rise due to heat generated by hydration. Its uses include
pavements and sidewalks, reinforced concrete buildings, bridges, railway
structures, tanks, reservoirs, culverts, sewers, water pipes and masonry units.
