ASTM C150

Full Name

ASTM C150 – Standard Specification for Portland Cement

Scope

ASTM C150 outlines the requirements for various types of Portland cement used in construction. It covers ten types of Portland cement, each with specific properties and intended uses:

  1. Type I – for use when the special properties specified for any other type are not required.
  2. Type IA – air-entraining cement for the same uses as Type I, where air-entrainment is desired.
  3. Type II – for general use, more especially when moderate sulfate resistance is desired.
  4. Type IIA – air-entraining cement for the same uses as Type II, where air-entrainment is desired.
  5. Type II(MH) – for general use, more especially when moderate heat of hydration and moderate sulfate resistance are desired.
  6. Type II(MH)A – air-entraining cement for the same uses as Type II(MH), where air-entrainment is desired.
  7. Type III – for use when high early strength is desired.
  8. Type IIIA – air-entraining cement for the same use as Type III, where air-entrainment is desired.
  9. Type IV – for use when a low heat of hydration is desired.
  10. Type V – for use when high sulfate resistance is desired.

The scope of ASTM C150 includes:

  • Chemical composition: requirements for the chemical constituents of each cement type, such as tricalcium silicate, dicalcium silicate, tricalcium aluminate, and tetracalcium aluminoferrite.
  • Physical properties: specifications for fineness, soundness, air entrainment, time of setting, and compressive strength.
  • Sampling and testing: procedures for sampling and testing Portland cement to ensure it meets the specified requirements.
  • Marking and packaging: guidelines for proper marking and packaging of cement.

ASTM C150 is a fundamental standard in the concrete industry, ensuring the quality and performance of Portland cement used in various construction applications. By adhering to the requirements of ASTM C150, cement manufacturers can produce consistent and reliable products that meet the needs of engineers and contractors.
