For obtaining representative sample for sieve analysis. It is suitable for dry sands, fine powders, ores, refractory materials, mineral aggregates, pigments, powered coal, soap, cement etc. Up to a maximum particle size of 3 mm.
The sampler consists of the following :-
For sampling aggregates, ores, refractory materials, pigments, powdered coal, soap, cement etc. It consist of the following :-
Same as HA50.10 except that it has 16 chutes of 25 mm width and three pans.
Used for determining the Flakiness Index of aggregates. It consists of a panel havingaccurately cut slots of different standard lengths and widths.
Required for determining the elongation index of coarse aggregate. It consists of a metal plate on which 8 steel pins are vertically mounted with specified distances in between. This assembly is mounted on a hardwood base.
Required for determining the bulk density or unit weight of aggregates.
Three calibrated cylindrical measures one each of 3 litre, 15 litre and 30 litre capacity made out of steel sheet with handles, complete with one tamping rod 16 mm dia x 60 cm long rounded at one end.
For determining the weight per cubic meter, yield, cement factor etc. freshly mixed concrete. The set comprises one each of 10 litre and 20 litre capacity cylindrical measures complete with handles.
For determination of specific gravity and water absorption of aggregate. It is made of G.I. wire-mesh of approximate size 20 cm dia x 20 cm high. Complete with handle.
Buoyancy balance is a multi purpose type of unit with electronic balance for the determination of density of the sample, weight in water, volume of the sample, or for analysis of fresh concrete.
The unit consists of a tubular frame, a carriage connected through chain to a ratchet. Balance is kept on the top of the table and has a hook for hanging the specimen. Powel and ratchet is provided to raise the plate form along with the plastic container filled with water. Balance has the capacity of 16kg.
For determining voids of dry compacted filler.
It comprises the following :-
For determining the slump of fine aggregate in estimation of absorption of fine aggregate.
It consists of the following :-
For determining the abrasion value of coarse aggregate.
It consists of the following :-
Same as HA 50.55 except that it has a digital preset counter.
Used for estimation of abrasion value of coarse aggregate.
The machine comprises the following :-
The machine is same as HA 50.60 except that it has pre-set electronic counter
For determination of the resistance of aggregates to surface wear by abrasion. The apparatus comprises the following :-
Suitable for operation on 220 V, 50 Hz, single phase supply.
Required for determining the Impact Value of coarse aggregate.
It consists of the following :-
Used for determining the Aggregate Crushing Value, The apparatus consists of a steel cylinder 75 mm dia, a plunger and a steel base plate. The surfaces coming into contact with the aggregate are case ardened.
Same as HA 50.85 but with 150 mm dia steel cylinder and plunger.
The reaction container is one of the important apparatus, required for determination of the Potential Alkali Reactivity of aggregates by chemical method when used in concrete having high alkali cement. It is made from stainless steel and fitted with air tight cover, held in position with special clamp.
Used for determining the resistance of flooring tiles to wear or abrasion.
It consists of the following :-
Used for polishing the road aggregate specimens for determining the polished stone value.
It consists of :-
Suitable for operation on 220v, 50 Hz, single phase supply.
This apparatus consists of a spring-loaded rubber shoe mounted on a pendulum arm. The pendulum arm can be adjusted vertically from a rigid suport column when in operation. The base has three adjustable feet so that the swing of the pendulum during test moves through a truly circular path while in operation directly on a road surface. An essential feature of this apparatus is the fact that the slider is made from a carefully graded rubber specially selected and certified by Transport and Road Research Laboratory of Great Britain . All bearing and working parts are enclosed.
