ASTM Test Method for Static Segregation Resistance of Self-Consolidating Concrete

This brief article reports on a fourth test method for use with self-consolidating concreted, published by ASTM International. Self-consolidating concrete (SCC) must have the ability to flow under its own weight, to pass between reinforcing bars or other obstacles without segregation, and not segregate during or after casting. Three earlier ASTM standard test methods were reviewed in 2009. This test method, ASTM C1712, provides a test method for the rapid assessment of static segregation resistance. The test does not measure static segregation resistance directly, but provides an assessment of whether static segregation is likely to occur in normal weight concrete. The test method uses the penetration apparatus and an inverted slump cone. After the slump cone is filled, the hollow cylinder is aligned in the center of the cone and lowered onto the concrete surface. After 30 seconds, the penetration depth is measured. Less penetration means a higher degree of static segregation resistance.
