ACME-705 Liquid Limit Device IS: 2720 - Part V, IS: 9259, BS: 137, AS: 89.
Casagrande method in mechanical form is known as Liquid Limit Method and has been in use for soil mechanics for a number of years. The Liquid Limit data of soils is useful to correlate m echanical properties of soil, such as compressibility and lower shear strength. Liquid Limit is the water content at which soil passes from zero strength to an Infinitesimal strength, hence the true value of liquid limit cannot be
determined. For determination purpose liquid limit is that water content at which a part of soil, cut by a groove of standard dimensions, will flow together for a distance of 1.25 cm under an impact of 25 blows in a standard liquid limit apparatus. The soil at the water content ha s some strength which is about 0.17 N/cm sq (17.6 gms/sq.cm). At this water content soil
just passes from liquid state to plastic state.

This is for mechanical analysis and also other laboratory
applications for stirring speed approximately 4000 rpm under load. A dispersion cup is supported on a rest on the stand of the stirrer and has a removable baffle. For operation on 230 - 250 volts A.C. supplied without dispersion cup or baffle.

Accessories :

Conventionally particle size distribution analysis is carried out using pipette and hydrometer methods.
Whereas in hydrometer method it is possible to de termine particle sizes in the range 75 microns, the method involves computation and it is time consuming. The pipette method can be used for determining only the percentage of specific sizes less than 0.02, 0.006 and 0.002 mm as a percentage of total soil sample. The plummet balance method to determine sub sieve particle size for the entire range is very rapid and only
manipulation of height of the balance, so that plummet sinks to the right depth is required. The percentage of soil in suspension is directl y indicated by a pointer over a
graduated scale.

Specifications :
A vertical rod is mounted on a sturdy base having leveilng screws. A pointer with steel pivots turns in jewel bearing and moves over a graduated scale. Scale graduations are marked 0 - 1O"x2% To the other end of the pointer a plummet is hanged. Rack and pinion arrangement is provided on the vertical rod for: adjusting the height. Supplied with a chart showing relationship between "K" and temperature of
suspension of soils of varying specific gravity from 2.4to 2.8 to help in solving stroke's equation. Supplied complete with one perspex plummet one measuring jar and one rider weight
for zero adjustment and one rider weight for adjusting the pointer to 100%.

ACME-718 Universal Automatic Compactor Is: 2720 - Part VII & VII.
Now-a-days almost every soil laboratory conducts compaction and penetration tests on soils. In both standard and heavy compaction tests the operator has to count the number of blows of the rammer on each layer of soil during compaction.
A mechanically cum electrically operated automatic compactor is therefore device to eliminate tedious hand compaction process. Which also considerably saves time. With the rammers provided two stroke lengths, available, the compactor can be used for normal compaction/heavy compaction as well as C.B.R. compaction.

Specifications: It is a motor driven mechanical compactor useful for soil compaction into 100 mm or 150 mm diameter moulds. Two sets of rammers are provided, one of 2.6 and arranged for 310 mm. drop and other 4.9 kg and arranged for 450 mm fall. For compaction soil into 150 mm diameter
moulds, 100 mm face diameter rammers having weights 2.6 kg and 4.89 kg are used. Where as for 100 mm diameter moulds they a re of 50 mm dia. The rammer assembly is provided with a ratchet and pawl arrangement to lift it from the top of the soil layer. When the rammer reaches the required height
the pawl release the rammer which falls freely on soil surface. The release mechanism is operated by an arm moving up and down which is connected to a reduction gear coupled to the motor through another arm.

An automatic blow counter fitted to the compactor is used to set the number of blows. The base plate of the specimen mould is to b e fitted to the rotating base plate of the instrument which makes 1/5th revolution per stroke. The
equipment is suitable for operation on 230volts, 50 cycles, single phase, A.C. supply. Moulds are to be ordered separately.
