ASTM C33 (Standard Specification for Concrete Aggregates)

ASTM C33 is a standard that sets the guidelines for the quality and characteristics of aggregates used in concrete, such as sand and gravel. It ensures that these materials are suitable for producing strong, durable concrete by specifying size, cleanliness, and composition. The standard helps manufacturers and builders select the right aggregates to ensure the safety, longevity, and performance of concrete structures. By following ASTM C33, the construction industry aims to maintain consistent quality in concrete products, ultimately supporting the safety and reliability of buildings and infrastructure.
