The Digital compression Testing Machine available with us is fabricated to test concrete for its compressive strength. Ensuring simple design and hassle free operation, this equipment is very easy to handle and can be used in rugged application conditions as well. Vouching for quality, we ensure that this equipment is very useful for site and laboratory applications in the construction industry.

Specifications:

• Available with pace rate controller to ensure maintenance of constant of loading
• High stability four column load frame
• Ensure stability and alignment in each frame to avoid tension failure during a test
• Ensure centre loading
• Standard Platens for 3 X 6”/ 4 X 8” and 6 X 12” cylinders included.
• A precise large diameter spherical upper platen for optimum results
• Availability of optional accessories for cubes, blocks, bricks and flexure test
• Motorized hydraulic power pack or pumping unit
• Automatic over load protection
• Comes standard
• Available with safety Guards on all four sides

The Abrasion Testing Machine is available hollow cylinder design which can be mounted horizontally on a sturdy frame on ball bearings. The opening can be closed with a dust tight cover to ensure easy charging and discharging of the drum with the material under test. Further, it also has a detachable shelf that spreads all through the inside length of the drum that ensures abrasive charge and restricts its falling on the cover.

Specification:

• The drum is rotated by an electric motor through a heavy reduction gear at a speed of 30-33 r.p.m.
• A revolution counter is fitted to the frame
• Available with tray for collection of the material at the end of the test.
• Ideal for operation on 440 volts, 3 phase, 50 cycles, and A.C. supply
• Abrasive charges includes a set of twelve hardened steel balls, approximately 48 mm diameter

This is used for determining the ductility of bituminous materials by measuring the elongation before breaking when two ends of a briquette specimen are pulled apart at a speed of 50mm/min + 2.5mm/min at temperature of 27⁰C + 0.5⁰C.

GENERAL DESCRIPTION & SPECIFICATIONS:

The Machine consist of the following :

1.    Stainless steel bath

2.    Temperature controller (Thermostatic/Digital)

3.    Immersion electric heater

4.    Constant speed Pump cum stirrer

5.    Carriage holding up to three standard briquette moulds

6.    Electric motor with gear mechanism

7.    Stainless steel scale and pointer

8.    Control Panel

The apparatus consists of water bath with a thermostatic heater and a circulating pump to maintain uniform water temperature.  One half of the briquette moulds is fixed in a fixed plate in the water bath, the other half of the briquette mould is fixed to a carrier which slides over a rotating  threaded shaft with a clutch. The motor and gears to rotate the shaft are housed in a cabinet fixed above the other end of the both. A pointer fixed to the carrier moves over. a scale graduated from 0-110 cm x 1mm fixed on the bath with “0” (Zero) of the scale towards the fixed plates side. The rotating shaft has 2 speeds of travel for the bracket, 5 cm/min. and 1cm/min. selected by a clutch. Water bath inside is of Stainless steel with insulation and a  water drain. A heater with thermostatic control is fitted. inside the water bath. Control switches for motor, stirrer, heater and indicator lamps are fitted to a control panel located at a convenient place on the water bath. Complete with three briquette moulds and one base plate. Working on 230 Volts, single phase, 50 cycles, AC.

OPTIONAL FITTINGS AT EXTRA COST

1.   Digital Temperature indicator cum controller (in place of Thermostatic control)

2.   Digital display for Elongation

3.   The more advanced model with refrigeration system which ensures better temperature control in tropical conditions. The Machine is mounted on a steel stand with refrigeration unit at its base.

4.   Base Plate for mould.

5.   Mould for elastic recovery.
