According to an embodiment, there is provided herein a method of determining the air void distribution in a sample of fresh concrete. One embodiment of the invention determines a parameter related to air void distribution by applying a known pressure to a fresh concrete sample, measuring a first value representative of the volume under compression, releases at least a portion of the pressure, reapplies the same pressure to the sample, measures a second value representative of the volume under the second compression, and uses differential between the first and second values to estimate a parameter related to the air void distribution.
