Sand Cone Test - Bali
The sand cone test is a commonly used field test in civil engineering to determine the
in-place density of compacted soil or granular materials. It is primarily used for evaluating the
relative density or compaction of soils during construction projects. The test involves the
following steps:
Preparation: A test hole is excavated in the ground to the desired depth and diameter,
typically using a hand auger or a mechanical excavator.
Collection of Test Sample: A representative sample of the excavated soil is collected and
weighed. The sample is then dried and weighed again to determine the moisture content.
Sand Filling: The hole is refilled with a known amount of dry sand. The sand is carefully
poured into the hole while ensuring that no air voids are formed.
Sand Density Measurement: The volume of the hole is determined by collecting the excess
sand that does not fit into the hole. The collected sand is weighed to determine its density.
Calculation: Using the weight of the sand and the known volume of the hole, the bulk density
of the compacted soil can be calculated. The moisture content of the soil sample is also
taken into account to calculate the dry density.
Repeatability: Multiple tests are often conducted at different locations within a project site to
ensure representative sampling and to account for variations in soil conditions.
The sand cone test provides a measure of the in-place density of the compacted soil or
granular material. This information is important in verifying that the soil or material meets the
desired compaction requirements specified in engineering design or construction standards.
The test is commonly used in the construction of embankments, roadways, foundations, and
other civil engineering projects where achieving proper compaction is crucial for the stability
and performance of the structure.
