ASTM C142
Full Name
ASTM C142 – Standard Test Method for Clay Lumps and Friable Particles in Aggregates
Scope
ASTM C142 focuses on the determination of the approximate amount of clay lumps and friable particles present in both fine and coarse aggregates.
The scope of ASTM C142 includes:
- Purpose: to evaluate the acceptability of aggregates with respect to requirements for clay lumps and friable particles as specified in ASTM C33 (Standard Specification for Concrete Aggregates).
- Materials: both fine and coarse aggregates used in concrete.
- Test procedure: involves soaking the aggregate sample in water, breaking down clay lumps and friable particles manually, and then sieving to separate and quantify the broken-down material.
- Significance: clay lumps and friable particles can negatively impact the durability and performance of concrete. This test helps ensure that the aggregates used meet specified quality standards and are suitable for their intended use.
By following ASTM C142, the construction industry can better assess the quality of aggregates and make informed decisions about their use in concrete, ultimately contributing to the production of durable and long-lasting concrete structures.
