ASTM C595
Full Name
ASTM C595 – Standard Specification for Blended Hydraulic Cements
Scope
ASTM C595 is a standard specification that pertains to blended hydraulic cements used in general and special applications. These cements are created by combining portland cement clinker or portland cement with supplementary cementitious materials (SCMs), such as:
- Slag: a by-product of iron and steel production
- Pozzolan: a siliceous or aluminous material that reacts with calcium hydroxide to form cementitious compounds
- Limestone: a source of calcium carbonate.
Key aspects of the scope of ASTM C595 include:
- Classification – the standard classifies blended cements based on the type and amount of SCM used:
- Type IS – portland blast-furnace slag cement
- Type IP – portland-pozzolan cement
- Type IL – portland-limestone cement
- Type IT – ternary blended cement.
- Composition: it specifies the chemical and physical requirements for each type of blended cement, including limits on the content of various oxides, fineness, and setting time.
- Performance: it outlines the performance requirements for blended cements, such as strength development and soundness.
- Test methods: it references other ASTM standards for testing the properties of blended cements.
The primary purpose of ASTM C595 is to provide a standardized framework for evaluating and specifying blended hydraulic cements. This ensures that these cements meet the necessary quality and performance standards for their intended applications in construction.
