Proper compaction of cement concrete while casting specimens for compression testing is essential to achieve a better and more consistent mixture. CSIC vibrating table is ideally suit for this purpose. The table top is 500 mm. x 500 mm. size and has stops along its edges to prevent moulds from sliding off the table during operation. The maximum load capacity is 140kg. The variable pitch pulley arrangement permits the frequency to be varied steplessly between 60 cycles/second and 43 cycles/second. Suitable operation on 415 volts, 3 phase, 50Hz, AC supply.
