ASTM C937
Full Name
ASTM C937 – Standard Specification for Grout Fluidifier for Preplaced-Aggregate Concrete
Scope
ASTM C937 defines the requirements and test methods for grout fluidifiers used in preplaced-aggregate concrete. Grout fluidifiers are chemical admixtures designed to increase the flowability and workability of grout without adversely affecting its strength or durability.
Key aspects of ASTM C937:
- Materials: the standard covers grout fluidifiers that can be added to grout mixtures consisting of Portland cement, pozzolan, fine aggregate, and water.
- Requirements: it specifies the physical requirements for grout fluidifiers, including their effect on bleeding, efflux time, and compressive strength of grout.
- Test methods: it outlines the procedures for testing grout fluidifiers to ensure they meet the specified requirements. These tests include bleeding, efflux time, and compressive strength tests.
- Significance: grout fluidifiers play an important role in preplaced-aggregate concrete construction by enhancing the flowability of grout, which allows it to penetrate and fill the voids between coarse aggregates effectively. This improves the bond between the grout and aggregates, resulting in a more durable and stronger concrete structure.
By adhering to the requirements and test methods outlined in ASTM C937, manufacturers and users of grout fluidifiers can ensure the quality and performance of their products, leading to improved construction practices and durable concrete structures.
