CRD C48
Full Name
CRD C48 – Standard Test Method for Water Permeability of Concrete
Scope
CRD C48 is a standard test method used to determine the water permeability of concrete. This test is essential for evaluating the durability of concrete structures, particularly those exposed to water or moisture. The test involves subjecting a concrete specimen to a constant water pressure and measuring the rate at which water passes through the specimen.
Key aspects of the CRD C48 test include:
- Specimen preparation: the test requires a cylindrical or cubic concrete specimen.
- Test setup: the specimen is placed between two porous stones and a constant water pressure is applied to one side.
- Water flow measurement: the rate of water flow through the specimen is measured over a specified period.
- Calculation: the water permeability of the concrete is calculated based on the measured flow rate, specimen dimensions, and applied pressure.
Applications of CRD C48:
- Durability assessment: the test is used to assess the durability of concrete structures, such as dams, bridges, and marine structures.
- Material evaluation: it is used to evaluate the quality of concrete materials, including aggregates, cement, and admixtures.
- Mix design: the test can be used to optimize concrete mix designs for specific applications, such as those requiring high water resistance.
