Sand Cone: Dig out the dirt being tested for compaction, weigh it, heat it until absolutely dry, and weigh it again. (Determines the weight of water in the dirt sample. ) Then, using the sand cone device, fill the hole level with sand, using the device gradations to measure the sand volume. Then, using a math formula with the weight measurements and the volume of the sample, calculate the existing dry density of the dirt sample.
Half a day later (seems like), go advise the equipement operator as to whether he is getting enough compaction to meet your specs.
Nuclear Density Guage: Turn on and calibrate the guage once in the morning. For each test, drive a probe in the dirt to be sampled, position the guage over the hole, then, unlocking the handle, push the radioactive source into the hole, usually at selectable depths. Wait 30 to 60 seconds, and look at the readout, which will tell you wet and dry density of the soil, and usually these days, the percent of compaction of the soil at that location. Tell the operator whether the compaction meets your specs, or not.

How can you find the volume of a quantity of sand?
almost the same way as most liquids because sand is in very little grains.ANS2:Since there is air between the grains, the volume is somewhat variable depending on how packed the sand is. To get the volume of the sand, pour the sand into water and measure the change in water level.

What is the coefficient of friction between steel and sand?
Between 0.194 and 0.306. Source: https://circle.ubc.ca/bitstream/handle/2429/27995/UBC_1989_A7%20R56.pdf?sequence=1
What is the difference between radioactive decay and radiometric dating?
It is the difference between sand running out of an hour glass and determining what time it is by how much sand is left. Radioactive decay happens at a steady rate. If you can determine how much of that radioactive isotope ought to have been in a sample at the start and you can measure how much is left, you can tell how much time has passed.

How do you find the radius and the slant height of a heap of sand in the shape of cone?
the slant height of a right circular cone is the distance from any point on the circle to the apex of the cone . The slant height of a cone is given by the formula ,√r2+h2 where r is the radius of the circle and h is the height from the center of the circle to the apex of the cone.
What are the Limitations of sand cone method?
it dries fairly quickly and can cause cracks when dried. hope this was helpful
In soil mechanics what is sand cone method -?
The Sand Cone Method is a sand replacement method for determining the field unit weight or the in-situ density of natural or compacted soil. There are three standard procedures used for determining this weight, including the Sand Cone Method, Rubber Balloon Method and the Nuclear Method. In the Sand Cone Method, as done in this lab, a hole is excavated in the area where the soil has been compacted and the dry weight of the soil can be obtained by determining the weight of the moist soil and the moisture content. The volume for the hole excavated is calculated by reintroducing the sand into the hole and then the dry unit weight of compaction is calculated by dividing the dry weight of the soil by the volume of the hole. This test method is applicable for soils without appreciable amounts of rock or coarse materials in excess of 1 1/2 in. (38 mm) in diameter. The main application of this test is the cases like embankment and pavement construction, this is basically a quality control test where a certain degree of compaction is required. This test is also used in stability analysis of embankments and slopes, for the calculation of pressure in underlying strata for settlement problems and also design of underground structures.
