HARVARD MINIATURE COMPACTOR:

Introduction:

This is for demining the moisture density relation of soils. (relationship between the moisture content of soils and resulting densities (oven-dry weight per cubic foot) when the soil is compacted in the laboratory with this apparatus).

General Description and Specifications:

In this apparatus, small quantity sample is compacted under kneading action of the spring loaded tamper set either at 10 kg or 20 kg. As the sample required is very small, a number of tests can be carried out, each time taking a fresh sample. The time required for compaction is very much less. The mould can be interchangeably used with Miniature Field permeameter where permeability tests can be conducted at high pressures. The apparatus consists of-

• Mould of 1.3 inch dia. x 2.6 inch high, made of mild steel, complete with collar and base plate,.
• Compaction Tamper with spring
• Collar remover
• Sample ejector.
