It consists of a pressure-tight flanged cylindrical measuring bowl, fitted with a removable flanged and a conical cover assembly with a seal in-between. The conical cover has an air valve and a petcock for bleeding off the water. A cylindrical standpipe, which is graduated in percent air content, is fixed to the conical cover assembly. Required pressure is applied to the specimen with the help of a pressure bulb. The recommended limits specified for the air content are between 3% and 6.5%.Each apparatus is supplied complete with a calibrating cylinder, pressure gauge, funnel, trowel and tamping bar

SHIVAM offer Compression Testing Machines are the finest of their type obtainable. The rugged construction and extreme simplicity make it possible for even non-technical personnel to operate them with ease and complete dependability. In particular, the portable units, which are small in dimension and light in weight, make quality control testing possible in areas where commercial testing facilities are not available and where the transportation of larger and much heavier machines would be difficult. SHIVAM Compression Testing machines conform to the requirements of IS: 516 and other International Standards like BS and ASTM Some of the salient features are

• High stability,
• Self-aligning platen assembly
• Gauges are calibrated in kN against certified proving rings, Suitable for testing cubes and cylinders of various sizes
• Using special platens, bricks can also be tested

Optional

• Digital readouts available with manual pace rate control and peak hold facility
• A fully automatic computerised version is also available.

A brief general description of these machines is
Loading Unit The loading unit is of fully welded construction having a cross head, base and solid side plates. The hydraulic jack is fixed to the base or on the top. The platens of the machine are hardened, ground and polished. The upper platen is provided with self-aligning action. To facilitate testing of various size specimens, suitable size spacers are provided.
Pumping Unit The hydraulic pumping unit is
1) Manually Operated or
2) Electrically operated The loads are measured on Bourdon tube type pressure gauges, which are calibrated against certified proving rings. The pressure gauges are fitted with a maximum load pointer. Both the Pumping units, manually operated and electrically operated, are of two-speed design. In the Electrically Operated Pumping Units, Pressure gauges are fitted with micro switches to switch-off the motor when the load approaches the maximum capacity of the pressure gauge, avoiding any over-loading. Relays are incorporated so that the motor does not restart own after a power breakdown.

The Electrically operated pumping units can also be fitted with hand-operated pump as an option

The Digital Compression Testing Machine has been designed to meet the need for a simple, economic and reliable means to test concrete for its compressive strength. The design emphasizes simplicity, both of construction and operation, and makes machine easy to use and maintain. The unit is compact, making it useful for site applications. The digital machines are provided with a pace rate controller, to enable maintain a constant rate of loading. The Complete unit comprises:
Loading Unit Is of fully welded construction having a cross-head with a spherical seated platen. The lower platen is attached to the top of the piston. The Loading Units of capacities, 1,000 kN, 2,000 kN and 3,000 kN are available. Cubes up to 300 mm & Cylinders up to 300 mm dia x 300 mm height can be tested using the appropriate models.
Pumping Unit The two speed pump facilitates rapid approach of the platens for daylight closure and also provides comprehensive control over the application of load. A control valve provides fine control over the loading rate for accuracy of pacing. The digital read-out unit incorporates a 4 digit display, calibrated in kN and features integral load pacing in kN/Sec (Auto pace rate controlled unit only). Maximum load is held and retained, unless cancelled, using the panel mounted reset switch. Pace rate set for running the test can be maintained manually with the help of a bar graph indicator.
