| Compression Testing Machine (CTM) 2000 KN (200 Tons) |
 |
Four Pillar Model - Electrically Operated fitted with dual display i.e load gauge 0-2000 KN x 10 KN/ Division and Digital Load Indicator 2000 KN x 1 KN/ Division. The micro switch fitted in load gauge and relay contact in digital load indicator to protect the machine from overloading. The machine is suitable for operation on 440V, 3-phase, Ac supply |
|
| Concrete cube mould (50 units) |
 |
Made of cast iron.
Size: 150x150x150mm.
Weight: 7-8 kg. |
|
| Vibrating table |
 |
Designed to carry a load of 140 kg. The apparatus consists of a single phase motor fitted with a variable pitch pulley housed in a cabinet. The vibrations are imparted by means of off-balance masses rotating on a shaft of a vibrator clamped to the underside of the tabletop. The tabletop is 90cm x 90cm and has stops along its edges to prevent moulds from walking off the table during vibration. A cross arm adjustable on a vertical rod at the centre of the table is provided to hold the moulds while operating the table. The variable pitch pulley arrangement permits the frequency to be varied sleeplessly between a maximum of 3600 vibrations per minute. A speed regulation handle is provided for increasing or decreasing the frequency. A switch is provided for starting the motor. Works on 220 Volts. |

| Vicat Needle Apparatus |
 |
This instrument is used for determining the normal consistency and setting times of cement and 'A' Class limes. The apparatus consists of a metallic frame bearing a freely movable rod with a cap at top, one vicat mould, cone type and glass base plate and one set of needles one each initial needle, final needle and consistency plunger. Fitted with dash pot. |
|
| Gyrotary Sieve Shaker |
 |
Carries up to 7 sieves of 150mm or 200mm diameter. The shaker is driven by a ¼ H.P motor through a reduction gear immersed in oil. The sieve table does not rotate but is inclined from the vertical axis and the direction of inclination changes progressively in clockwise direction. If the stop-pin below the table is removed, the shaker can have a rotary motion. In addition to this gyratory motion of the table, there is an upward and downward movement ensuring that each square cm of the sieve is utilized. A pair of rods and holder are supplied. The holder can be fixed on the top of the upper most sieves and thus the sieve set is firmly held. Suitable for operation on 230 Volts, 50 cycles single phase, A.C. Supply. |
|
| Laboratory Concrete Mixer |
 |
The Mixer consists of a steel vessel of 55/ 110 liters capacity (Aprox.), for mixing of 1cft. Mounted on a frame. The vessel is rotated at 20-22 RPM with the help of a motor. The vessel can be titled to any angle by a hand wheel and counter weight. This facilitates mixing and discharge. Blades are provided inside the vessel to mix the material thoroughly. The large hand wheel facilitates manual rotation of the drum during power failure. The drum, motor, etc, are mounted on a steel frame. This mould is provided with two large wheels for carting away. The mixer is provided with ½ HP motor. Suitable for Operation on 220V, Single Phase, 50Hz, AC Supply. |
|
| Slump Test Apparatus |
 |
It is used for the determination of the consistency of freshly mixed concrete, where the maximum size of the aggregate does not exceed 38mm. The Apparatus consists of one slump cone with handles and foot pieces. The slump cone has internal dimensions 20cm. diameter at base 10cm. top diameter and 30cm height. Foot pieces can be fixed to the clamps on the base plate. The base plate has lifting handle for easy transportation. One graduated steel rod 16mm dia x 600mm long, rounded at one end and graduated in mms, is also supplied. |
