| Description | Price |
| Maximum dry density of sand: NGI-Geolabs Recommended Method Statement (As published in ‘Development of new robust procedures for the determination of maximum and minimum dry densities of sand’ by Knudsen.S et al at ISFOG 2020 {delayed publication}) This test is performed using a vibrating apparatus with the vertical amplitude digitally controlled according to the method statement. Note: this rate does NOT include a quantitative validation that the fines content is within the 12 % fines that the method statement specifies. If more than a visual assessment is required, please add one of the extra items listed below. |
