Jolting Apparatus
IS 1727 1967, IS 4031 1968, ASTM C 394, C 64
For making standard rectangular specimens of 40 x 40 x 160mm. of Portland and pozzolana cement mortar for determining the transverse strength.
Specification:
The jolting apparatus consists of a rectangular table rigidly connected by two support arms to a spindle at a horizontal distance of 800 mm from the centre of the table. There is a projecting lug with a plane face on the upper face of the table beneath which is a stop with a rounded upper surface. The table can be raised and allowed to fall freely on the stop by a cam which is connected to a motor and gearbox through a V-belt an pulleys. The cam rotates at a rate of 60 Rev/Min. A stroke counter fitted with micro-switch is provided which stops the machine after 60 Jolts. Locating pins are provided for mounting the mould compartments on the table. The mould surmounted by the hopper can be clamped rigidly to the table. Supplied complete with mould and hopper. Suitable for operation on 230 Volts, Single Phase, A.C. Supply. A Digital Preset Counter can be supplied at an extra cost.

Vibration Machine
Ref. Standard – IS:4031, IS:10080, EN 196-1 413-2, EN 13454-2
A specially designed Vibration Machine is used for vibrating the mix in moulds at a frequency of 12,000 ± 400 cycles per minute, as per specifications.
The Vibrator is mounted over coiled springs and the vibrations are developed by means of a revolving eccentric shaft. The centre of gravity of the vibrator, including the cube and mould, is either at the centre of the eccentric shaft or within 25mm below it. The simple design of the machine facilitates easy assembly and dismantling of the cube moulds. Each machine is supplied AIM 414 one cube mould with ISI Certification Mark and poking rod.
Suitable for operation on 220V, 50Hz, Single Phase, AC supply.
