There is no requirement to pull a spread test in our demonstration because we are not looking for flow ability – we are performing a "Slump" test and testing for consistency.
We were not out to determine whether or not the concrete needed a flow test; rather, we're simply demonstrating the proper method for performing ASTM C-143 Standard Test Method for Slump of Hydraulic-Cement Concrete.
When shooting multiple takes in a lab setting and continuously washing our equipment, our 5" slump quickly moved to about a 9-1/2".
Please don't post comments about a need to perform a spread test, based on the appearance of the slump.
