ASTM C150/C150M-20 PDF Download

The ASTM C150/C150M-20 standard covers the specifications and requirements for eight types of portland cement: type I, type IA, type II, type IIA, type III, type IIIA, type IV, and type V. Each type of cement has specific properties and uses.

The standard specifies the chemical compositions that each type of portland cement must contain, including aluminum oxide, ferric oxide, magnesium oxide, sulfur trioxide, tricalcium silicate, dicalcium silicate, tricalcium aluminate, and tetracalcium aluminofernite.

Various test methods are provided to evaluate properties such as air content of mortar, chemical analysis, strength, false set, fineness, heat of hydration, autoclave expansion, time of setting, sulfate resistance, calcium sulfate, and compressive strength.

The standard also outlines guidelines for storing the cement, emphasizing the need for easy inspection and identification of each shipment and proper protection from dampness.

It is important to note that the specification includes explanatory material in the form of notes and footnotes, which are not considered as requirements of the standard.
