ASTM C1105
Full Name
ASTM C1105 – Standard Test Method for Length Change of Concrete Due to Alkali-Carbonate Rock Reaction
Scope
ASTM C1105 covers the determination of the susceptibility of a coarse aggregate or cementitious materials aggregate combinations to expansive alkali-carbonate reaction. This reaction involves hydroxide ions associated with alkalies (sodium and potassium) and certain calcitic dolomites and dolomitic limestones.
The test method measures the length change of concrete prisms over time. The results help assess the potential for deleterious expansion in concrete structures due to alkali-carbonate reaction.
The scope of ASTM C1105 includes:
- Determining susceptibility: the test method helps determine if a specific coarse aggregate or combination of materials is susceptible to expansive alkali-carbonate reaction.
- Measuring length change: the test involves precise measurement of changes in the length of concrete prisms over a specific period.
- Assessing expansion potential: the results provide valuable insights into the potential for harmful expansion in concrete due to the alkali-carbonate reaction.
- Guiding material selection: the information obtained from the test helps engineers and constructors choose appropriate materials to prevent damage to concrete structures.
It’s important to note that ASTM C1105 does not provide interpretation of the test results. For guidance on interpreting the results, you can refer to ASTM C1778.
