About Standard Compaction Test (BS Version)
Specification:
The apparatus consists one each of compaction mould steel, 105mm I.D. x 115.5mm height x 1000 cc. volume, complete with collar and base plate. Compaction Rammer is 2.5 kgs. in weight x 300mm controlled fall. Face of the rammer is 50mm
- Mould: A cylindrical metal mould with a 100 mm internal diameter and 127.3 mm height, providing a volume of 1000 cm. A collar and a detachable base plate are also included.
- Rammer: A 2.6 kg (5.7 lbs) metal rammer with a guide sleeve and vent holes for controlled operation and uniform energy.
- Blow Count: The rammer is designed to deliver a controlled drop of 310 mm.
- Blows per Layer: Each layer is compacted with 25 blows.
-
1. Prepare the Soil:
The soil sample is passed through a 20 mm sieve and mixed with a controlled amount of water.
-
2. Layering:
The soil is placed into the mould in three equal layers.
-
3. Compaction:
The rammer is dropped from the specified height (310 mm) to compact each layer.
-
4. Drying:
After compaction, the mould is cleaned and weighed to determine the mass of the compacted soil. A separate sample is dried in an oven to determine the moisture content.
-
5. Calculations:
The dry density and moisture content are calculated for each trial to develop the dry density versus moisture content curve.
The standard compaction test establishes the relationship between the moisture content and the dry density of a soil, determining its maximum dry density and optimum moisture content. This information is crucial for achieving the required density and strength of compacted soil in civil engineering projects like dams, embankments, and highways.

Quality Assurance and ComplianceFactory calibration with certification guarantees measurement reliability, while the powder-coated steel finish offers lasting corrosion resistance. Noise emissions below 65 dB and compliance with BS standards affirm its suitability for professional laboratory environments.
FAQ's of Standard Compaction Test (BS Version):
Q: How is the Standard Compaction Testing Machine operated for soil assessment?
A: The machine can be operated in manual or automatic mode using the provided keypad and switches. Users place the soil specimen in the supplied mould, set the desired drop weight (2.5 kg or 4.5 kg), and initiate compaction at a test speed of 47 blows per minute for precise moisture-density relationship evaluation.
Q: What accessories are included with the compaction machine upon purchase?
A: The accessory pack contains a compaction mould (100 mm or 150 mm diameter), rammer, and tamper, all needed for standard soil compaction tests. A user manual and factory calibration certificate are also provided for guidance and quality assurance.
Q: When should I calibrate or service the compaction machine?
A: Factory calibration is provided during delivery. For optimal performance, it is recommended to have the machine recalibrated annually. The product comes with a 12-month service warranty, covering necessary maintenance during this period.
Q: Where is this equipment commonly used?
A: This compaction testing machine is primarily utilized in laboratory settings, often by dealers, distributors, exporters, manufacturers, and research institutions involved in soil analysis. Its bench or table-mount design supports installation in most laboratory environments.
Q: What benefits does the hammer lock and guard safety mechanism offer?
A: The integrated hammer lock and guard protect users by preventing accidental release of the hammer and reducing risk during operation, enabling safer and more controlled compaction processes.
Q: Does the machine conform to specific standards or regulations?
A: Yes, the device strictly adheres to BS 1377: Part 4 specifications, guaranteeing accuracy, reliability, and industry compliance for soil compaction testing in professional environments.
