Standard Test Method for Determining Consistency and Density of Roller-Compacted Concrete Using a Vibrating Table

Importancia y uso:

5.1 This test method is intended to be used for determining the consistency and density of stiff to extremely dry concrete mixtures common in roller-compacted concrete construction.

5.1.1 Because of the stiff to extremely dry consistency of some roller-compacted concrete mixtures, the standard Vebe test method of rodding the specimen in a slump cone is substituted by Procedures A and B.8

5.2 Procedure A uses a 22.7 kg [50 lb] surcharge and is used for concrete consolidated by roller-compaction methods when the consistency of the concrete is very stiff to extremely dry.

5.3 Procedure B uses a 12.5 kg [27.5 lb] surcharge and is used for concrete consolidated by roller-compaction methods when the consistency of the concrete is stiff to very stiff consistency, but not extremely dry.
