It is a motor driven mechanical compactor useful for soil compaction into 100 mm or 150 mm diameter moulds. Two sets of rammers are provided, one of 2.6 and arranged for 310 mm. drop and other 4.9 kg and arranged for 450 mm fall. for comaction soil into 150 mm dia moulds, 100 mm face dia rammers having weight 2.6 kg and 489 kg are used. Where as for 100 mm dia moulds they are of 50 mm dia. The rammer assembly is provided with a ratched and pawl arrangement to lift it from the top of the soil layer. When the rammer reaches the required height the pawl release the rammer which falls freely on soil surface. The release mechanism is operated by an arm moving up and down which is connected to a reduction gear coupled to the motor through another arm. An automatic blow counter fitted to the compactor is used to set the number of blows. The base plate of the specimen mould is to be fitted to the rotating base plate of the instrument which makes 1/5th revolution per stroke. The equipment is suitable for operation on 230 volts, 50 cycles, single phase, A.C. supply. Without Moulds.

Note : Mould are to be ordered separately.

The Laboratory Cement Autoclave is suitable for conducting accelerated soundness test on Cement or the Autoclave expansion test. The Equipment meets the requirement of IS: 4031(Part-3)

The Equipment consists of a Stainless Steel/Mild Steel Pressure Vessel with insulated outer shell fabricated. The Pressure inside the vessel is controlled through a Pressure gauge and spring-loaded safety valve for control of Heater unit.

Specification :

Specification :
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.

A specially designed Vibrating Machine is used for vibrating the mix in moulds according to strictly controlled programme at a frequency of 12,000 ± 400 cycles per minute. The vibrator is mounted over coiled springs and the vibrations are developed by means of a revolving eccentric shaft. The center of gravity of the vibrator, including the cube mould, is either at the center of eccentric shaft or within 25mm below it. The simple design of the machine facilitates easy assembly and dismantling of the cube moulds. The machine is suitable for operation on 220V, 50Hz, single phase, AC supply.

Specifications :
The Apparatus consists of one slump cone with handles and foot pieces. The slump cone has internal dia 20cm at base 10cm top dia 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 mm is also supplied.

The design of concrete mix is aimed at maximum durability for the conditions prevailing at the site where it is to be used. Ability to resist the flow of water through, is one of the important durability characteristics. The permeability is determined on cement, mortar and concrete specimens, either cast in the laboratory or obtained by cutting out cores from existing structures.
