STANDARD COMPACTION TEST

Standard Compaction Test Apparatus (ASTM 4-Inch Model)

Product Code  :   MSI 3018

Standard Used  :  ASTM D698 | ASTM D558 

Engineered to satisfy American testing protocols for standard laboratory compaction effort (Method A & B) and soil-cement mixture evaluations.

Product Description
The Multitech Scientific Instruments MSI 3018 Standard Compaction Test Apparatus is a precision laboratory assembly manufactured strictly to American Standard (ASTM) engineering constraints. Commonly referred to as the Standard Proctor Test, this apparatus is used to establish the baseline moisture-density relationship of soils. By delivering a controlled mechanical compaction impact via a 2.5 kg (5.5 lb) rammer dropping from a fixed 12-inch height, laboratories can easily determine the Optimum Moisture Content (OMC) and Maximum Dry Density (MDD) for foundational earthworks.

• Features

  • ASTM-Calibrated 4-Inch Mould: Machined from high-tensile tool steel to ensure a perfectly uniform internal testing volume of precisely 944 cc.

  • Friction-Free Guide Plunger: The compaction rammer features a built-in steel guide tube that guarantees a constant 12-inch free fall with zero manual tracking bias.

  • Standard 2-Inch Impact Face: Designed with a flat 2-inch diameter striking face, ensuring a standard energy distribution footprint over each soil layer.

  • Heavy-Duty Structural Build: Engineered to withstand the relentless mechanical fatigue of laboratory compaction sequences without altering internal volume tolerances.

• Application

  • Used to determine structural soil compaction metrics (OMC and MDD) according to American ASTM infrastructure protocols.

  • Indispensable for evaluating shallow foundations, roadway subgrades, retaining wall backfills, and soil-cement structural bases.

  • Deployed internationally by commercial export laboratories, third-party inspection firms, and civil engineering universities.
