Standard Test Method for Static Segregation of Self-Consolidating Concrete Using Column Technique

Importancia y uso:

5.1 This test method provides users with a procedure to determine the potential static segregation of self-consolidating concrete.

Note 1: This test method may not be sufficiently rapid to evaluate self-consolidating concrete mixtures in the field before placement. Test Method C1712 provides a rapid method for assessing static segregation resistance of self-consolidating concrete.

5.2 This test method shall be used to develop self-consolidating concrete mixtures with segregation not exceeding specified limits. Self-consolidating concrete is a fluid concrete that can be prone to segregation if not proportioned to be cohesive. A cohesive self-consolidating concrete is important for all applications but is especially critical for deep-section applications such as walls or columns. Therefore, the degree of segregation can indicate if a mixture is suitable for the application.

Note 2: Some level of segregation is tolerable as long as the desired strength and durability performance is achieved.
