STANDARDS: ASTM D1556 | AASHTO T191 | NF P94-061-3 | CNR N° 22 | UNE 7371
Used to determine the in-situ density of fine graned compacted soil
and to verify the degree of compaction.
The test consists in digging a hole into the ground and then collect,
dry and weight the sampled soil.
The hole is now filled with dry sand from the cone container and the
volume of sand recorded.
Three versions are available Ø 4” 6.5” 12” each one suitable for
different grain sized.
The S231KIT model Ø 12” is recommended for coarse grained soil
and gravel (over 38 mm diameter).
The kit consists of:
Metal double cone assembly with valve, galvanized for rust
protection.
Metal base with rimmed centre hole for cone housing, galvanized.
Two plastic jar, 5 litre capacity. (One jar only 15 litre capacity
complete of cone fixing device for S231 KIT version)
The calibrating container is an accessory, to be ordered separately.
