The grain size distribution of soil fraction passing through 75 micron IS sieve can be carried out as per IS:2720 (Part-IV) by pipette method or by hydrometer method.
Test is performed as per IS:2720 (Part-IV) The apparatus comprises of:-
Test is performed as per IS:2720 (Part-IV). Used for particle size analysis of soil in suspension when it has more than 10% of 75 micron IS sieve passing material. The scale on the hydrometer is marked from 0.995 to 1.030 in terms of density (g/ml) of suspension at 27°C.
Test is performed as per IS:2720 (Part-IV). It is single marked 1000 ml glass cylinder without pour out, used to prepare the soil suspension for the determination of density by using HS10.37 Hydrometer. Supplied complete with the rubber bung.
Internal dimensions 600 mm x 300 mm x 380 mm deep with clear glass sides. Complete with heater, thermostat and agitating unit capable of maintaining temperature at 27º ± 1ºC. When ambient temperature is less than 27ºC. Wired for 220V, 50 Hz, 1 Phase operation.
The test is performed as per IS:2720 (Part-IV). The unit comprises of :-
The apparatus is used to determine the relative proportion of fine dust or clay like material in soils or fine aggregates either in the laboratory or in the field. It is performed as per IS:2720 (Part-37). The apparatus consists of the following:-
Operated Test is performed as per IS:2720 (Part-37).
Used for shaking ingredients of graduated acrylic cylinder for Sand Equivalent tools.
Motion of the carriage is through hard wheel. Hand Wheel is rotated at a speed so as to achieve about 175 strokes/min.
The system is same as HS10.47.3 except that the drive is through electric motor. The motor drive operates the shaking mechanism at approximately 175 ± 2 strokes per minute through a stroke length of 8”. Suitable for operation on 220V, 50 Hz, single Phase supply.
