Swell Test Apparatus

It is designed to determine the swelling pressure developed by soil specimens moulded to desired densities at known moisture contents, when soaked in water.

The load applied to restrain the swelling is transferred to a load measuring proving ring through a perforated swell plate and a load transtor bar. The proving ring is attached to the lead screw of load frame, hand operated designed for the purpose. The load frame has a worm and gear arrangement for initial setting and for subsequent volume change compensation. A soaking tank is provided for saturating the specimen and base of the mould has channeis and radial grooves with connecting holes.
