If rodding is the method of consolidation, how many layers should the measure be filled in?

When using rodding as the method of consolidation for a concrete measurement, the standard procedure involves filling the measure in three layers. This practice is essential to achieve uniform density and ensure that the material is adequately compacted, thereby reducing the potential for voids.

Rodding each layer contributes to the thoroughness of the consolidation, allowing for better penetration of the rod into the mixture. Each layer is typically rodded separately, which helps in achieving a more accurate representation of the sample's density and strength characteristics. Therefore, filling the measure in three layers with rodding promotes an effective consolidation process, which is a critical aspect of standardized testing procedures in concrete quality assessments.
