Methodology:

A Control Grout was created using Ordinary Portland Cement (OPC) and Sand. The flow tests depicted on the video are as follows:

1. Control Grout with no admixture
2. Control Grout with 0.25% RheoActiv SP 1
3. Control Grout with 0.25% RheoActiv SP 2
4. Control Grout with 0.25% RheoActiv SP 3
5. Control Grout with 0.20% RheoActiv SP 4
6. Control Grout with 0.75% of the leading melamine powder

Water content was kept identical on each flow test. The test shows the increase in workability achieved without the need to increase the water content. By the same principle the water content can be significantly reduced (by up to 40%) without decreasing workability.
