High Pressure Permeability Test can be conducted on different size specimens using different cells. Each cell is made of steel and provided with a top plate and funnel at the bottom having gasket seals held in position through bolts and nuts. The concrete specimens are sealed in the cell to prevent any leakage along the side walls. The permeated water is collected in glass bottles attached at the bottom. Each test stall has its own control system, operating pressure gauges and valves. The pressure sight glass tubes are fully protected by a shatter proof panel The multi-unit per-meameters are so designed that all tests can be performed at the same time, using either the same head or varying head pressure, as each test stall is provided with its own pressure regulator and control. The control instruments are mounted on a sturdy welded structural stand. All multi-units are provided with end pressure gauges. Each unit is provided with chamber pressure gauges of 0-20 kg/cm2 and test pressure gauges of 0-15 kg/cm2. Pressures are applied using any available pressure line at the site or a compressor.

Pocket Concrete Penetrometer

Concrete Penetrometer, Spring Type
IS: 8142-1976
It consists of cylindrical spring housing with a plunger attached to the top of the spring. Penetration needle is attached to the other end of the spring housing. The plunger is graduated in 1 kg divisions, to a maximum capacity of 60 kg, which can be read with respect to the top end of the spring housing. A set of six needle points with areas of 645, 323, 161, 65, 32 and 16 mm2 are provided. Supplied complete in a wooden carrying case.

This test is considered suitable for cohesive and plastic mixes of concrete containing aggregate smaller than 50 mm

IS: 7320, BS: 1881, ASTM C 143, AASHO T119
Slump Test Apparatus
The slump cone is filled with freshly mixed concrete and is tamped with a tamping bar in three or four layers. The top of the concrete is leveled off with the top of the slump cone, the cone is lifted vertically up and the slump of the sample is immediately measured
Features
Base has cleats on its underside to help dig into the ground surface Positive clamping of slump cone to the base while filling and rodding the concrete A combination swivel carrying handle also doubles as the datum making the conventional and somewhat awkward measuring procedure of using a foot rule and a datum bar, a thing of the past Supplied complete with base plate, having cleats and swivel handle

Slump cone
Conforms to IS: 7320, BS: 1881, ASTM C 143, AASHO T 119 specifications. Made of sheet steel, suitably protected against corrosion.

IS:516
Tamping Bar of 16 mm dia x 60 cm long

Proper compaction of cement concrete while casting specimens for compression testing is essential to achieve a better and more consistent mixture. Suitable for operation with 220 V, 1 phase, 50 Hz, AC Supply.

Vibrating Table with load cap 140kg, variable frequency
The table top is 1000 mm x 1000 mm size and has stops along its edges to prevent moulds from sliding off the table during operation. The maximum load capacity is 140 kg. The variable pitch pulley arrangement permits the frequency to be varied step lessly between 60 Cycles/sec and 43 Cycles/sec

For setting up fresh concrete, it should vibrate while casting the structure.

It consists of sheet metal and fitted with heater having thermostatic controller to maintain the temperature. While conducting the compression test of concrete casting moulds. It should cure properly as per standard
Curing tank

Curing tank suitable for 24 cube mould of 150 mm. Temperature range from ambient to 100 Degree Cent.

IS: 516, BS: 1881, ASTM C31 ASTM C617
While casting the cylindrical moulds both side of mould should be flat and parallel when conducting a compressive strength test. These capping sets are for use in the field and in the laboratory.
