Pore Pressure

The pore pressure measuring apparatus consists of a screw pressure pump, null indicator in Perspex, pressure gauge, mercury manometer, volume change burette and the necessary connecting tubes and valves. It is used for measuring pore water pressure and pore air pressure in soils. It has many features, which simplify the operation. The Null Indicator is made from a transparent Perspex block. It is a simplified U-Tube Null Indicator, in which water can bypass mercury if null indicator is tilted; thus de-airing process by circulation of water is facilitated. All features enable a visual check to be made during the de-airing operation of apparatus. A mercury manometer and a pressure gauge of Bourdon Tube type are provided on the panel on which the whole equipment is mounted. Very small positive or negative pressures are observed on the manometer. A 50 ml burette is clamped to a sliding bracket on one side of the panel. It is used for measuring the volume change in the specimen when subjected to confining pressure in the triaxial cell.

The following models of Pore Pressure Apparatus are offered :

Specific Gravity

Specific Gravity is the ratio of the weight in air of a given volume of a material at a standard temperature to the weight in air of an equal volume of distilled water at the same stated temperature. The equipment mentioned below can be used to test a wide range of materials from clay to sand and gravel smaller than 10 mm.

Sample Riffle Divider

IS: 1607-1977, 2720, ASTM C 136, D271, D421, D422, D423, D424, D427, D451, D452, D457, D806, BS: 812, 1377, AASHO T27, T87.
For the rapid collection of true representative samples from aggregates, sand and fillers, sample divider is required. Riffle Sample Divider consists of a metal box fitted with a series of chutes of equal width, which discharge the material alternatively in opposite directions into separate pans. The chutes of the riffle are steep enough to allow rapid flow of the material. Supplied complete with three containers.

The sample extractors shown in this section meet the requirements of Indian, British, ASTM and AASHO standards. Soil core specimens can be extracted from sampling tubes with minimum disturbance. Specimens of smaller dia can also be extracted from larger size samples.
