ASTM C387
Full Name
ASTM C387 – Standard Specification for Packaged, Dry, Combined Materials for Concrete and High Strength Mortar
Scope
ASTM C387 covers the requirements for pre-packaged dry mixes intended for use in concrete and high-strength mortar applications. These products are typically mixtures of cementitious materials, aggregates, and sometimes admixtures, which are combined with water at the job site to create the final concrete or mortar mixture.
The scope of ASTM C387 includes:
- Materials: it specifies the types of materials that can be used in the dry mixes, including Portland cement, blended hydraulic cements, aggregates, and admixtures.
- Physical requirements: it outlines the physical properties that the dry mixes must meet, such as compressive strength, air content, and fineness modulus.
- Packaging and labeling: it provides guidelines for packaging the dry mixes and labeling them with essential information like product type, brand name, net weight, and mixing instructions.
- Yield: it requires the manufacturer to indicate the yield of the dry mix, i.e., the volume of concrete or mortar produced per unit weight of the mix.
- Testing Methods: it references other ASTM standards for testing the properties of the dry mixes and the resulting concrete or mortar.
The standard applies to several types of dry mixes, including:
- Normal strength concrete
- Lightweight concrete
- High strength mortar
- Mortar for use with unit masonry
ASTM C387 is important for ensuring the quality and consistency of packaged dry mixes used in construction. By specifying the requirements for materials, properties, packaging, and testing, the standard helps to ensure that the dry mixes produce concrete and mortar that meet the desired performance standards.
