Product Details:

Motorized ASTM: D 1559- T –62.
Generally the test is applicable to hot mix designs using bitumen and aggregates uptoa maximum size of 25mm. In this method, the resistance to plastic deformation of
cylindrical specimen of bituminous mixture is measured when the same is loaded at periphery at 5 cm per min. This test procedure is used in designing and  evaluating bituminous paving mixes. The test procedure is extensively used in routine test programmers for paving jobs. There are two major features of the Marshall method of designing mixes namely, a) density – voids analysis b) Stability – flow tests. The marshall stability of mix is defined as a maximum load carried by a compacted specimen at a standard test temperature of 60oC. The flow value is deformation the marshall test specimen under goes during the loading upto the maximum load, 0.25 mm units. In this test and attempt is made to determine optimum binder content for the type of aggregate mix and traffic intensity.

The apparatus consists of: 1) A loading unit motorized, capacity 5000kgf with two telescopic pillars and an adjustable cross head.Limit switches are fitted inside to control upward or downward movement of the pillars. On-off reversing switch and indicator lamps are on the front side while a hand wheel to manually move the pillars is on the right. The load frame Standard Accessories: Marshal Mould:3 Nos, Marshal Rammer:2 Nos, Pedestal :1 Nos, Braking Head:1 Nos.

Product Details:

Ductility is defined as distance in cms to which a standard briquette of bitumen can be stretched before the thread breaks. The briquette is stretched at a rate of 50 mm /min. /2.5 mm per minute at a temperatureof 27oC /0.5oC.

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 on a fixed plate in the water bath, the other half of the briquette mould is fixed to a carrier which slides over a rotating the 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 bath. A pointer fixed to the carrier moves over a scale graduated from 0-110 cm x 1 mm 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 1 cm/min. selected by a clutch. Water bath inside is aluminium/ S. steel, its is an insulated water bath Water bath is provided with a drain. A heater with thermostatic control is fixed inside the waterbath. Control switches for motor pump heater and indicator lamps are fixed at aconvenient place on the water bath. Complete with three briquette moulds andone base plate, steel all made of brass operates on 230V A.C. supply single phase.

Product Details:

Concrete Moulds are easily cast by using a tamping bar or a vibrating table.  However air trapped in cement mortar paste can not be thus removed while casting cement mortar moulds.  Easy method is to impart greater vibration of lesser amplitude to the mould while casting.  This is achieved in a Vibrating Machine.  Vibrating Machine is used for the preparation of mortar cubes for the determination of compression strength of ordinary and rapid hardening Portland cement, low heat Portland cement, Portland blast furnace cement and high alumina cements.

 

Specifications: 
The machine consists of a vibrating frame assembly and an electric motor mounted on a sturdy base.  The complete frame assembly consists of a vice to hold a 7.06cm cube mould and two studs threaded at top and a hopper to feed the sample in the mould.  This assembly is supported on four springs and has an in built rotating shaft which rotates eccentrically and thus imparts vibrations to the entire frame.  A balance weight is an integral bottom part of the frame.  The centre of gravity of the assembly is brought to the centre of the eccentric shaft or within a distance of 25mm below it.  The electric motor drives the shaft of the frame and thus imparts required vibrations to the mould.  The frequency of vibration is 12000 ± 400 vibration per minute.  Supplied complete with a 7.06cm cube mould and loose base plate, a time switch 0-5mins x 1 min and certificate of vibration.

Product Details:

Used for the determination of bitumen percentage in bituminous mixtures. It consists of a removable, precision machined aluminum rotor bowl (accessory 1500 or 3000 g capacity), housed in a cylindrical aluminum box. The separate control panel incorporates an electronic card fitted with AC drive that automatically drives the bowl speed rotation ramp from 0 to 3600 R.P.M. as requested by Standards, with automatic fast stop bowl rotation at the end of the test. Supplied complete with speed regulator and digital display monitoring the frequency. Power supply: 230 V A.C. Single Phase.

 

Product Details:

It is designed for finding out the deformation and strains on 15cms. Diameter and 30 cms. High cement concrete cylinders when subjected to compressive loads. 

Product Details:

It is used for compacting concrete cubes and cylinders.

 

Specifications: Sizes: 75cmx75cm 100cmx100cm. To carry out a load of 140kg.  The unit consists of a 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 table top.  The table top is 50cm x 50cm and has stops along its edges to prevent moulds form 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 step Lesley between a maximum of 3600 vibrations down to 2600 vibrations per minute.  A speed regulation handle is provided for increasing or decreasing the frequency a switch is provided for starting the motor.  Suitable for operation on 440 Volts, 3 phase, 50 cycles, A.C.Supply.

Product DescriptionPrinciple Of Operation:
There is a silicon solar photocell placed on top of the sensor mount, so that it is having a large viewing angle almost 180 degrees. The f sun’s presence is computed by the following principle, A shadow-band is rotated around the sensor to obtain the total incoming radiation, and diffused radiation (when the sensor is covered by the shadow band) by comparing the diffused and total radiation, we can assert the presence of sun. The shadow-band width is sufficient to cover the sun so that, a shadow falls on the sensor at any angle of sun. To minimize sensor position shift during seasonal sun’s change we have provided sufficiently large shadow-band. The output of the sensor is amplified and the variation between the diffused and total is compared using a precision analog comparator and driven through a mono stable multi-vibrator. There is a LED indication on the top, which indicates the presence of sun; this will help during installation and adjusting the threshold levels.For Threshold adjustments a potentiometer is provided this potentiometer can be accessed by removing the water tight rubber bushes on the sensor body. The sensor is already set for it’s optimum levels from factory.
