ASTM C
ASTM C refers to a series of standards established by ASTM International, an organization that develops and publishes technical standards for materials and products. The "C" signifies that these standards focus specifically on construction materials, including cement, concrete, and masonry. These standards provide guidelines for testing, quality assurance, and performance to ensure safety, reliability, and consistency in building materials. They are used by manufacturers, engineers, and construction professionals to ensure materials meet industry requirements and regulations, ultimately helping to create safer and more durable structures.

ASTM C 136 is a standard test method used to determine the particle size distribution of aggregates, which are materials like sand, gravel, and crushed stone commonly used in construction. The process involves passing aggregates through a series of mesh screens, each with different-sized openings. By weighing the amount of material that remains on each screen, we can create a profile of the aggregate's size distribution. This information is crucial for engineers to ensure that the materials meet specific requirements for strength and durability in concrete and asphalt applications.

ASTM C 150 is a standard published by the American Society for Testing and Materials that specifies the requirements for portland cement, a key ingredient in concrete. This standard outlines various types of cement, their chemical and physical properties, and the testing methods to ensure quality and consistency. By adhering to ASTM C 150, manufacturers ensure that the cement produced meets safety and performance standards, which contributes to the durability and strength of concrete used in construction projects, ranging from buildings to roads.

ASTM C 472 is a standard that outlines the procedures for testing the physical properties of gypsum plaster and other related materials. It ensures that these materials meet specific performance criteria, such as strength, durability, and adhesion. The standard provides guidelines for preparing samples, conducting tests, and reporting results, helping manufacturers and builders assess quality and consistency. By adhering to ASTM C 472, stakeholders can ensure that products perform well in construction and meet safety standards, ultimately contributing to the reliability of structures using gypsum-based materials.
