ASTM C796
Full Name
ASTM C796 – Standard Test Method for Foaming Agents for Use in Producing Cellular Concrete Using Preformed Foam
Scope
ASTM C796 is a standard test method designed to assess the performance of foaming agents used in the production of cellular concrete with preformed foam. This involves evaluating the foaming agent’s ability to generate stable foam with desirable properties, such as density, air content, and stability.
Key aspects covered by ASTM C796:
- Purpose: the main purpose is to measure the performance of a foaming chemical in a laboratory setting to simulate its behavior in producing cellular concrete.
- Foam properties: the test evaluates the density and air content of the foam produced by the foaming agent. It also assesses the stability of the foam by measuring its drainage and collapse over time.
- Mixing and pumping: the test method simulates the mixing and pumping processes involved in cellular concrete production, allowing for a realistic evaluation of the foaming agent’s performance under practical conditions.
- Specimen preparation: the generated foam is used to create cellular concrete specimens, which are then tested to determine their properties, such as density and compressive strength.
- Significance: the results of this test method are crucial for selecting appropriate foaming agents and optimizing the mix design for producing high-quality cellular concrete with desired properties.
By following the standardized procedures outlined in ASTM C796, manufacturers and users of foaming agents can ensure the consistency and reliability of their products, leading to improved performance and durability of cellular concrete in construction applications.
