In-situ Density Proctor Penetrometer Sand Replacement Sand Cone 6" Core Cutter Apparatus Field density tools Many civil engineering projects require the use of fill material. Whenever soil is placed as an engineering fill, it is usually compacted to a dense state, to obtain satisfactory engineering properties.

The in-situ density of the material is given by the weight of the excavated material divided by the in-situ volume. Objective(s) of the Experiment The test is carried out in order to determine the relative compaction of the soil, that is, how well the soil compacted is on …

 · Two calculation methods for the dry density estimation technique are presented. • A numerical calibration approach considering thermal contact resistance is offered. • The feasibility and effectiveness of the technique are verified in the field test. • The technique can realize quasi-distributed in-situ dry density measurement.

In-Situ Density Testing Our network of accredited field technicians can be readily available to complete any In-Situ Density Testing for construction and environmental industries. We can test your earthworks on site for density and shear strength, including soil, sand, gravel, saturated clays, and silts.

 · From the steps and equipment of this experiment, we can see the calculation is too rigorous in order to find out the in-situ density, thus, the chances of errors can also be minimized. In conclusion, the results is acceptable due to the reasonable data. Errors: 1) Sand bulk: The water is bleeding into calibrated sand due to high moisture content.

 · The objective is to determine (a) the dry density and (b) the moisture content, and then find the relative or degree of compaction using equation 13.1. There are three methods commonly used for determining the in-place or field density. These are the sand-cone method, the rubber balloon method and the nuclear density meter method.
