Question: 1 / 400

How many strokes are required for air meter rodding of a 15L specimen?

10 strokes

25 strokes

40 strokes

For the air meter rodding of a 15L specimen, the correct number of strokes is 40. This procedure is essential in concrete testing to ensure that the sample is adequately consolidated before measurements are taken.

The rodding process involves inserting a rod into the concrete and moving it up and down to remove air pockets and voids. The integrity of the test results relies on proper consolidation, as any trapped air can lead to inaccuracies in the measured volume of the concrete.

Using 40 strokes, as prescribed by the standard testing methods, ensures that the concrete is well compacted and allows for an even distribution of the material in the testing apparatus. This helps to achieve reliable results when assessing the properties of the concrete being tested.
