Portland Type I/II & III
Type I/II Portland Cement is uniquely formulated to provide the basic performance characteristics of Type I Portland Cement, as well as the moderate sulfate resistance and lower heat of hydration characteristic of Type II Portland Cement. Type I/II Portland Cement can be used in massive structures, such as heavy piers, foundations, abutments, and retaining walls, as well as common Type I projects, such as roads, bridges, reinforced concrete buildings, tanks, reservoirs, culverts, water pipe, sidewalks, and masonry units. Suwannee American Cement Company Type I/II Portland Cement exceeds all applicable ASTM, Federal, State highway and AASHTO specifications for Portland Cement, and can be shipped by bulk or packaged.
Type III Portland cement provides strength at an earlier period than normally expected. For example, strength may be achieved in a matter of days as compared to the typical expectation of 28 days. Type III is chemically similar to Type I cement, except that its particles have been ground finer. It is used when forms need to be removed as soon as possible or when the structure must be put into service quickly. In cold weather its use permits a reduction in the length of the curing period.
