Proctor Moulds and Compaction Hammer

Proctor Moulds and Compaction Hammer – Soil Compaction Testing

The Proctor Moulds and Compaction Hammer are essential instruments used to determine the optimum moisture content and maximum dry density of soils—key parameters for geotechnical engineering and construction quality control. Compliant with international standards such as ASTM D698 (Standard Proctor) and ASTM D1557 (Modified Proctor), this compaction testing set ensures consistent and accurate results in both laboratory and field settings.

The equipment includes a robust steel cylindrical mould and a calibrated drop hammer, designed to deliver uniform compaction energy, making it ideal for compaction curve development and density-moisture relationship analysis.
