ASTM C1611

Full Name

ASTM C1611 – Standard Test Method for Slump Flow of Self-Consolidating Concrete

Scope

ASTM C1611 outlines the procedure for determining the slump flow of self-consolidating concrete (SCC). This test method assesses the concrete’s ability to flow and fill formwork under its own weight without segregation or bleeding.

The scope of ASTM C1611 includes:

  • Slump flow measurement: the primary focus is measuring the slump flow of SCC, which is the average of two orthogonal diameters of the concrete mass after it has flowed freely on a non-absorbent surface. This measurement indicates the concrete’s consistency and flowability.
  • Self-consolidating concrete: the test method is specifically designed for self-consolidating concrete, a type of concrete with high flowability and resistance to segregation.
  • Coarse aggregate size: the test method is applicable to SCC containing coarse aggregates up to 1 inch (25 mm) in size.
  • Laboratory and field testing: the test can be conducted in both laboratory and field settings, providing flexibility for quality control and monitoring during concrete production and placement.
  • Significance and use: the slump flow test helps evaluate the consistency and unconfined flow potential of fresh SCC. It is a valuable tool for quality control, ensuring that the SCC meets the desired flow characteristics for proper placement and consolidation in formwork.
