ASTM C33
Full Name
ASTM C33 – Standard Specification for Concrete Aggregates
Scope
ASTM C33 defines the requirements for both fine and coarse aggregates used in concrete. It covers the grading (size distribution), physical properties (such as soundness and durability), and deleterious substances (materials that could negatively affect the concrete’s performance) of the aggregates.
The scope includes:
- Aggregate types: fine and coarse aggregates, excluding lightweight and heavyweight aggregates.
- Requirements:
- Gradation: distribution of particle sizes within specified limits.
- Physical properties: soundness, abrasion resistance, clay lumps, friable particles, etc.
- Deleterious substances: organic impurities, coal, lignite, etc.
- Applications: general concrete construction, but specific project requirements may necessitate additional or more stringent specifications.
- Usage: this specification is used by contractors, concrete suppliers, and other purchasers to define the quality of aggregates to be furnished.
The standard does not cover:
- Proportioning of aggregates in concrete mixtures.
- Testing methods (which are covered in other ASTM standards).
The aim of ASTM C33 is to ensure that aggregates used in concrete meet certain quality standards, contributing to the overall strength, durability, and performance of the concrete structure.
