IL - 212
Mortar Mixer, IS: 10890-1984
This apparatus has specially been designed to
prepare cement mortar for strength determination as specified in IS: 4031.
It can also be used in mixing lime with pozzolonic materials for
determination of lime reactivity (as per IS: 1727) and for uniform mixing of
soils with additives such as lime, cement, etc. The stainless steel mixing
bowl has a capacity of 4.75 liters. The paddle, also made of stainless
steel, can have both planetary and revolving motion for uniform mixing. It
can be electrically driven at two speeds

Crushing And Grinding
IL - 213
Pulveriser
- Designed for grinding materials to produce fine mesh samples.
- Ideal for use in cement and chemical industries
- Self contained grinder with a rotating disc having planetary movement
in vertical plane.
- Reduces about 450g quartz type material to 100 mesh in one minute.
- Sitable for operation with 440 V, three phase, AC supply.
Pallet Preparation
IL - 214
Ring Press (Hydraulic)
Used for making pallets of graphite or Infra Red transmitting materials.
For elemental analysis of Cement, lags or Refractoriness by X-ray
Fluorescence or Emission Spectrometry, the samples are mixed with graphite
powder and pallets are made in the Ring Press, compressing at desired
pressures. The pallets are suitable for placing in the analyzing
instruments. Similarly, in the analysis of samples in the powder form by the
Infra Red Spectrophotometers, these are mixed with NaCI or IR transmitting
materials and pallets made as above and placed in the instruments for
analysis.
The Ring Press is a portable bench model and can be
used on a sturdy tabletop. It is fitted with a load measuring gauge
calibrated for 0 - 250 KN and also fitted with a pressure release valve for
removing pallets. It is supplied with dies for different pallet sizes,
according to the requirements.

Vibration Machine, IS: 4031
A specially designed Vibration Machine is used for
vibrating the mix in moulds according to strictly controlled programmer 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
and mould, is either at the center of the eccentric shaft or within 25 mm
below it.
The simple design of the machine facilitates easy
assembly and dismantling of the cube moulds. The machine is suitable for
operation on 230 V, 50 Hz, and single-phase, AC supply. Each machine is
supplied with one cube mould. The following mould can be ordered, as
optional extra: Mould, M. Steel, for 70.6 cm cube
Note : The machine can certified for its frequency by the National
Council of Cement and Building Materials (NCCBM) at Extra Cost.
Consistency And Setting-Time
Apparatus described below have been designed for
determining the normal consistency, standard consistency and time of setting
of cement and lime in accordance with IS, ASTM, BS and AASHO specifications.
Vicat Method
IS: 2645, 2542 (Part-2), 1727, 5513, BS: 12, 146, 915, 1370, 4027, 4246,
4248, ASTM C-91, C-141, C-187,C-308, C-359, C-472 & AASHO T-129, E-131
The procedure, as recommended in various
standards, is for determining the quantity of water required to produce a
cement paste of standard consistency. The standard consistency is attained
when the 10 mm plunger of the apparatus penetrates the material to a
pre-determined depth under free-fall. A new sample is prepared and tested
with initial and final needles in accordance with the procedure described in
various specifications. Vicat Apparatus consists of a frame bearing a
movable rod with a cap at top and a vicat mould in the form of the frustum
of a cone, (80+5)/70 + 5mm dia at the base,(70mm+5mm) /60 mm at the top and
40 mm high, and with a glass base plate of minimum 2.5 mm thickness with
various models of Vicat apparatus
IL - 216
Vicat Apparatus, IS: 5513
The apparatus includes one each of :
- Vicat Mould, Glass Base Plate, Initial Needle (in Plastic Case),
Final Needle (in Plastic Case)
- Consistency Plunger (in Plastic Case)
- Extras
- Mild Steel Base Plate
- Vicat Mould, Split Type, with Clamping Ring
IL - 217
Vicat Apparatus with Dashpot, IS: 5513
This apparatus includes Dashpot to facilitate the
gentle lowering of the moveable rod.
Shrinkage Bar Mould
IS: 10086-1982, IS: 4031
ASTM C 151 also specifies the use of shrinkage bar moulds for the
determination of soundness. Length Comparator listed in the concrete section
determines the change in length of the specimen. Two models are offered. One
is provided with stainless steel smooth reference points and the other is
provided with knurled and threaded reference points. Both the models are
available as single mould and multiple mould compartments. Each mould is
supplied complete with base plate and two reference points per compartment
of mould.
Mould sizes: 25 x 25 mm section and 250 mm effective length (Distance
between two inner-most of the reference points) The models are available in
three kinds of apartments i.e. One, Two, Four with smooth and knurled
threaded reference points.
