The end faces of cylindrical cement concrete test pecimens must be plane, smooth and parallel so as to yield correct results during carrying out their compressive strength tests. Any imperfection remaining after casting the specimens, have to be removed by capping the specimens with cement or any other suitable capping compound. ‘HEICO’ offers two types of capping sets i.e. Horizontal and vertical for this purpose.
Capping Set (Horizontal) IS:516-1959 For capping 100 mm dia x 200 mm high cylindrical specimens in the field or in the laboratory.
It consists of the following :-
i) A machined base fitted with two brackets, one fixed, and the other movable horizontally. Both the brackets carry specimen holders. Each holder has a notch at the top for pouring the molten capping compound.
ii) Cylinder carrier for carrying the 100 mm dia. cylindrical specimens.
iii) A stainless steel ladle for pouring the molten capping compound into the notches of the capper.
For 100 mm dia x 200 mm high cylindrical specimens. For use in the field or in the laboratory. It consists of the following :-
The machine is used for compaction of 70.6 mm cube specimens of cement mortar under standard vibration required for determination of compressive strength of cement. The vibration machine consists of a frame mounted on four coiled springs to carry a cube mould and an eccentric revolving shaft mounted in ball and roller bearings. The machine is so balanced that the eccentric imparts simple harmonic motion to mould carrier and the mould. The frequency of vibration is 12000 ±400 per minute. The drive from the motor to the eccentric shaft is through an endless
flat belt running on crowned pulleys.
Suitable for operation on 220 V, 50 Hz, single phase supply. Supplied complete with a time switch, one 7.06 cm I.S.I. marked cube mould (HC42.10.1) with hopper.
[NOTE : The machine can be supplied with NCCBM/Sriram Test House certification on request.
The Vibrating Table is used for compaction of cement concrete cubes and cylinders by vibration. The load carrying capacity of the table is about 150 kg. The table is supported on rubber mounting springs and the housing of the eccentric is fitted below the table top.
The table is stops along all its sides to prevent the moulds from sliding away during vibrations. Table can accommodate four numbers of HEICO make 150 mm cube moulds.An operating switch is provided. Suitable for operation on 440 v, 50 Hz, 3 phase supply.
Used for molding of three standard specimens of 40 mm x 40 mm x 160 mm size from Portland and Pozzolana cement mortar for determination of their transverse strengths. The equipment consists of the following: –
Suitable for operation on 220 V, 50 Hz, single phase supply.
Used for preparation of plastic mortar of cement and pozzolanic materials for making different types of test specimens in the laboratory.
The apparatus comprises the following :-
Moulding specimens of Concrete is an important activity and good specimen can be achieved only if the cement paste covers the aggregate thoroughly and uniformly before pouring the concrete mix into standard moulds. The object of efficient mixing can be most satisfactorily achieved in HEICO Pan Mixers, which are available in 40, 60 & 100 liters.
These mixers have been designed and developed to mix both dry & wet materials. Manually controlled mixers are rotated by a turntable which is driven by an electric motor. The mixing pan is removable and can be tilted for easy emptying of the material. The mixing blades and paddle are made of special steel for fast and effective mixing operation and are long lasting to withstand wear & tear. Mounted on a sturdy but light Steel frame, they can be easily moved about on wheels.
