Description
Standard Compaction Test – BS 1377, 1924
The Precision Standard Compaction Test Apparatus from azalab is specifically designed to meet the requirements of BS 1377-4 and BS 1924-2, enabling accurate determination of the maximum dry density and optimum moisture content (OMC) for soil used in construction, roadwork, and geotechnical applications.aza
Used in Proctor-type tests, this apparatus simulates light compactive effort to ensure field compaction levels meet engineering specifications. It is a key quality control tool in any soil testing laboratory or on-site investigation.

How It Works
- Fill the mould with soil in 3 layers, each compacted with 27 blows from the 2.5 kg rammer
- Remove excess soil and weigh compacted sample
- Oven-dry the sample to calculate dry density
- Plot moisture vs. density to determine OMC
This standard compaction test ensures soil suitability for structural use.
FREQUENTLY ASKED QUESTIONS (FAQ)
Q1: Is this apparatus equivalent to the ASTM D698 version?
It is similar but slightly different. BS standards use a 2.5 kg rammer and 105 mm mould, while ASTM uses 2.6 kg and 100 mm.
Q2: Is it suitable for all soil types?
Best for fine-grained and medium plasticity soils. Coarse or gravelly soils require a heavy compaction test.
Q3: Can I request a gunmetal mould instead of steel?
Yes. Gunmetal moulds are available upon request for better corrosion resistance.
Q4: How accurate is this method?
Extremely accurate for field representation when procedures are followed per BS 1377/1924.
Q5: Is the equipment portable?
Yes, especially with an optional carrying case, ideal for both lab and field use.
