Standard
ASTM C230 defines the flow table test method for determining the consistency and workability of concrete and mortar mixes. This standard outlines the procedure for measuring the flow or spread of a mixture when subjected to standardized jolting or dropping actions. Essentially, it helps assess how easily the mixture can be placed and consolidated within a form or mold during construction.
Test Procedure of Flow Table Test
-
Preparation of Sample: Prepare the concrete or mortar sample according to the specified mix design and ensure it is properly mixed and free of any lumps or air voids.
-
Setup: Place the flow table apparatus on a stable and level surface. Ensure that the top plate is clean and free from any debris.
-
Mold Preparation: Place the mold on the center of the flow table and secure it firmly in place.
-
Filling the Mold: Fill the mold with the prepared concrete or mortar sample, ensuring it is evenly distributed and compacted within the mold.
-
Initial Measurement: Measure the height of the sample in the mold from the base of the mold to the highest point of the sample surface.
-
Release: Remove any excess material from the top of the mold and gently release the mold from the sample without disturbing its shape.
-
Jolting or Dropping Action: Lift the flow table apparatus and allow it to drop onto the surface of the sample from a specified height or subject it to a standardized jolting action.
-
Measurement After Action: After the jolting or dropping action, measure the height of the sample again using the same reference points as before.
-
Calculations: Calculate the flow or spread of the sample by subtracting the final height measurement from the initial height measurement. This difference represents the flow of the material under the applied action.
