Standard ENStandard Test Method for Slump Flow of Self-Consolidating Concrete
Also Known As:
The ASTM C1611/C1611M-21 standard is a test method used to determine the slump flow of self-consolidating concrete (SCC). The purpose of this test is to measure the consistency and unconfined flow potential of fresh, unhardened SCC. The test can be conducted in both laboratory and field settings.
The standard specifies that the test method is applicable to self-consolidating concrete with coarse aggregates up to 25 mm (1 inch) in size. It notes that it is challenging to produce SCC that is both flowable and non-segregating using coarser aggregates. Appendix X1 provides non-mandatory visual rating criteria to evaluate the ability of an SCC mixture to resist segregation.
The rate at which the concrete spreads during the test is related to its viscosity. Appendix X1 offers a non-mandatory procedure to assess the relative viscosity of SCC mixtures.
The standard includes references to notes and footnotes that provide additional explanatory information, but these should not be considered as requirements of the standard. It also includes a warning regarding the caustic nature of fresh hydraulic cementitious mixtures and the potential for chemical burns upon prolonged exposure.
