ASTM C1712 − 14 Standard Test Method for Rapid Assessment of Static Segregation Resistance of Self Consolidating Concrete Using Penetration Test

ASTM C1712 − 14 Standard Test Method for Rapid Assessment of Static Segregation Resistance of Self Consolidating Concrete Using Penetration Test

Scope
1.1 This test method covers the rapid assessment of static segregation resistance of normal-weight self-consolidating concrete (SCC).

The test does not measure static segregation resistance directly but provides an assessment of whether static segregation is likely to occur.

1.2 The test apparatus and protocol were developed based on tests with SCC mixtures containing saturated surface dry (SSD) coarse aggregates ranging in relative density from 2.67 to 2.79 and in nominal maximum size from 9.5 mm to 25 mm.

For SCC mixtures outside these ranges, testing is recommended to establish a correlation between penetration depth and static segregation measured in accordance with Test Method C1610/C1610M.

This test method shall not be used to assess the static segregation resistance of self-consolidating concrete containing lightweight aggregates or heavyweight aggregates without prior testing to establish a correlation.
