ASTM C136
Full Name
ASTM C136 – Standard Test Method for Sieve Analysis of Fine and Coarse Aggregates
Scope
ASTM C136 covers the determination of the particle size distribution of both fine and coarse aggregates using sieving. This information is crucial for understanding the gradation of aggregates, which significantly affects the properties of concrete, such as workability, strength, and durability.
The scope of ASTM C136 includes:
- Materials: fine and coarse aggregates used in various construction applications, primarily concrete and asphalt.
- Test procedure: sieving a known mass of aggregate through a series of progressively smaller sieves and determining the mass retained on each sieve.
- Calculations: calculating the percentage passing each sieve and plotting the results on a gradation curve.
Significance:
- assessing the suitability of aggregates for specific applications based on their gradation requirements.
- quality control of aggregate production to ensure consistency and compliance with specifications.
- optimization of concrete mix designs to achieve desired workability, strength, and durability.
ASTM C136 is a fundamental test method in the construction industry, providing a standardized approach for evaluating the particle size distribution of aggregates. This information is essential for ensuring the quality and performance of concrete and asphalt mixtures.
