In the concrete consolidation method using vibration, the appropriate procedure involves filling the measure in approximately two equal layers. This approach allows for effective consolidation of the concrete mix, as each layer can be adequately vibrated to remove air bubbles and ensure a uniform density throughout the sample. By using two layers, it facilitates more effective interaction between the vibrational energy and the concrete material. This ensures that the concrete is adequately packed and reduces the likelihood of voids or inconsistencies within the sample.

Filling the measure in just one layer can lead to improper consolidation, where the concrete may not be thoroughly compacted, resulting in pockets of air remaining within the material. If the measure were filled with an excessive number of layers, it might also hinder the effective vibration process since the top layers may not receive sufficient it’s a comprehensive vibrational effect. Consequently, the two-layer method strikes a balance between achieving complete consolidation while maintaining practical handling and measurement techniques in concrete testing.
