Flow table test Wikipedia
Conducting the test. The flow table is wetted. The cone is placed in the center of the flow table and filled with fresh concrete in two equal layers. Each layer is tamped 10 times with a tamping rod. Wait 30 seconds before lifting the cone. The cone is lifted, allowing the concrete to flow.
Explanation for Variations in Charpy Impact Test Results
A weight on a pendulum is raised. For example a 50 pound weight can be raised 3 feet (height h1 in sketch.) The weight is released and assuming very low friction bearings it will rise to a height h2. If for example that height is 1 foot then the energy absorbed was 50 lbs x .
