self consolidating concrete spread test-48

During the slump flow test, the viscosity of the SCC mixture can be estimated by measuring the time taken for the concrete to reach a spread diameter of 20 inches (500 mm) from the moment the slump cone is lifted up.

This is called the T) value may be appropriate for concrete that has to travel long horizontal distances without much obstruction.

The slump flow test, using the traditional slump cone, is the most common field test and is in the process of being standardized by ASTM.

The slump cone is completely filled without consolidation, the cone lifted, and the spread of the concrete measured.

This standard does not purport to address all of the safety concerns, if any, associated with its use.

It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.As a high-performance concrete, SCC delivers these attractive benefits while maintaining all of concrete's customary mechanical and durability characteristics.Adjustments to traditional mix designs and the use of superplasticizers creates flowing concrete that meets tough performance requirements.The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.Combining values from the two systems may result in non-conformance with the standard.It is important to test the concrete to avoid problems that could be costly.
