There will be no abrupt changes in the cross section of the hydrometer, that will hinder cleaning or drying or permit air bubble to be trapped. The graduation of hydrometer will be on the basis of liquid having a surface tension of 55 dynes/cm. The graduation lines will be at intervals of 0.0005, every alternate line will extend beyond the shortest lines; every tenth graduation will exceed that of all the intervening lines and will be numbered in full. The basis of the scale will be density (g/ml) at 27   deg C. The maximum permissible scale error on the hydrometer is plus or minus one scale division.

 The penetration tests determine consistency of bitumen for the purpose of grading. Depth in units 1/10 of millimeter to which a standard needle having a standard weight will penetrate vertically in a duration of five seconds at a temperature of 25 C determines penetration for gradation.

Concrete Penetrometer, Spring Type It consists of a cylindrical spring housing with a plunger attached to the top of the spring. Penetration needle is attached to the other end of the springhousing.

Essential Accessories : High sensitivity compression proving ring cap 200 kg One Consolidation dia gauge 0.01 mm x 25 mm and one strain dial gauage 0.01 mm x 25 mm and one strain dial gaine 0.01mm x 25 mm.

Optional Extras : Additional set of weights to give a normal stress of 5 kg/cm2. Soil Sampler for 60 mm x 60 mm specimen and test form pad of 50. Spares: Porous stone for 60 mm x 60 mm size sample available in pairs.

Buoyancy Balance helps in determining the specific gravity and for the water absorption of the aggregate. It is fitted with the 15 kg capacity x 0.5 gm of the electronic balance. The frame is supplied with:

??         Water tank,

??         Suspension hook

??         Lever for lifting the water tank manually

Specific gravity bottles determine liquid densities by measuring the difference between an empty and filled bottle and dividing by an equal volume of water to find the specific gravity of the substance. These bottles are also known as a density bottle or relative-density bottles.

The apparatus is used for the laboratory determination of permeability of soil using a constant or a variable head. This test is recommended for soils with co-effcient permeability in the range of 0 10 to 10 cm/sec. The maximum particle size of the soil which can be tested in the mould is 10mm.

These products are designed and developed using best quality material and ongoing technology as per the industry defined standards and norms by skilled professionals. Offered products can be availed in various specifications and are well known due to their exceptional finishing.

The Ductility Testing Machine is used to determine the ductility of bituminous materials in a briquette mould by measuring the breaking elongation at a constant speed of 50 mm/min. ... The Ductility Testing Machine comprises of speed control and water circulator to maintain the homogenous water temperature.

Used for testing crushed rock, crushed slag, crushed and uncrushed gravel for resistance to abrasion. The machine consists of a hollow cylinder mounted horizontally on a study frame and ball bearings. There is an opening which can be closed with a dust tight cover to facilitate charging and discharging the drum with the material under test. A detachable shelf which extends throughout the inside length of the drum which catches the abrasive charge and does not allow it to fall on the cover.

Scoops are used for transferring soil, cement, aggregate or any other grainy material or powders. They are made from 304 S.S. and fitted with handle.

With consists of a brass cup held on an adjustable bracket. The bowl can be adjusted for a fall raised & dropped on a rubber of standard hardness by cam action. Complete with one casagrande grooving tool, one ASTM grooving tools and a height gauge block. Hand operated, with counter

All moulds are made from steel, protected against corrosion. They are specially made for use with the automatic compactor, see Automatic Marshall compactors, ASTM. The three parts of the compaction moulds can be purchased individually. See spare parts. Conforming to ASTM D6926 (ex D1559), the compaction can also be performed manually. See Hand compaction assembly.

The apparatus consists of a rectangular-section box in the shape of an  L  with a vertical and horizontal section, separated by a moveable gate, in front of which vertical lengths of reinforcement bar are fitted.

Density Basket is Madeup of brass with stainless steel wire mesh 6.3mm size ruggedly constructed, approximately 20cm dia x 20cm high. Complete with handle. For density tests on aggregates as per procedure laid down.Salient Features.
