However air tapped 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. Vibration 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
bleast furnace cement and high alumina cements.
Salient Features
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 intergral bottom part of the frame. The center of gravity
of the assembly is brought to the center of the eccentric shaft or
within a distance of 25mm mould. The frequency of vibration is 12000 400
vibration per minute. Supplied complete with on 7.06cm cube mould with
loose base plate, a time switch 0-5mins x 1min and certificate of
vibration from a standard laboratory.
Spares : Set of Springs, Belt and Belt guard.
