Concrete Testing Equipment

Our concrete mixer is a motorized concrete mixer of laboratory type. These mixers are electrically operated and are designed so that the tedious job of hand mixing concrete can be eliminated. The mixer is highly useful in creating uniform mix of concrete. Our laboratory concrete mixers are suitable for operation on 220 / 230 volts A.C. single phase. Following are some essentials of our product:

• The counter balanced drum is easy to tilt and has a volume of 1.1/2 to 2 cu.ft.
• The total drum volume is however 3 cu.ft. mounted on a well built stand with rubber tyres, the drum is mounted for end discharge and equipped with end towing pole.

Our vibrating machine conforms to is 4031 - 1968. These machines that are used for the preparation of mortar cube or moulds. Further, these are used in the determination of compression strength of ordinary and repair hardening portland cement and low heat portland cement. Following are some technical specifications of our product:

• The complete frame assembly consists of a vice to hold a 7. 06 cm cube mould to feed the sample in the mould.
• The frequency of vibration is 12000 + 400 r. P. M, supplied complete with one 7. 06 cm cube mould.
• With the help of a time switch electric 0-5, minute operating current starts when dial knob is turned to any desired time and automatically cuts off when knob returns to zero.

We present cube mould with base plate which are available in different size. These are according to Indian and British Standards. For the metric size cube moulds the faces are machined flat to +/-0.2mm accuracy and finished to within 0.2mm.

Our beam mould are made of supreme quality metal which is why these are strong enough to resist distortion. These even retain their shape and size even under rugged conditions. From our end, we offer moulds of different sizes for cube, beam & cylindrical moulding which are required for compressive strength testing. These are manufactured in the following sizes:

• 100 mm x 100mm x 500 mm
• 150 mm x 150mm x 700 mm
• 150 mm x 150mm x 750 mm
• 150 mm x 150mm x 760 mm

Our cylindrical mould are manufactured as per Ref Std :IS 10086. These are high in efficiency and their working. Our moulds are available in cost effective prices. These can easily sustain in extreme climatic situations and can easily resist distortion. Further, these retain their shape and size even under rugged conditions. Following are the size specifications of cylindrical moulds:

• 50 mm dia x 100mm HT
• 75 mm dia x 150mm HT
• 100 mm dia x 200mm HT
• 150 mm dia x 150mm HT
• 150 mm dia x 160mm HT
• 150 mm dia x 300mm HT
• 150 mm dia x 300mm HT

• 450 mm dia x 900mm HT
• 500 mm dia x 1000mm HT

Proper compaction of cement and concrete while casting specimens for compressive or flexural strength testing essential to achieve a better and more consistent mixture. The cement and concrete vibrating table top has stops along its edges to prevent moulds from sliding off the table during operation. The maximum load capacity is 140 kg. The concrete vibrating tables are offered in 3 different table top sizes:

Kewil® Con-Vibra Series concrete vibrators [Needle Vibrators] are the finest of their types available. Their rugged construction and extreme simplicity makes it possible to operate them with ease and complete dependability. These Needle Vibrators are designed to suit all types of site conditions. Their superior design and longer life eliminate old fashioned arduous method of compaction.

Flexible Shaft: The flexible shaft is manufactured as per I.S.S. 6276/71 standards. The inner core consists of high tensile spring wires as per I.S.S. 4454/75 standards. The rubber outer casing is rugged enough to negotiate varied climatic conditions and has a wear resistant spring steel liner which guarantees a longer life and maximum transmission efficiency.

The Needles are of the out of balance rotor type as well as Pendulum type made to I.S.S. 2505/80 standard and are available in Standard sizes of 25 mm, 40 mm, 50m & 60 mm diameter, each suited and streamlined to a 6 meter or 4 meter flexible shaft powered by a motor or a Petrol or Petrol/Kerosene engine. Connections of drive shafts to unit are by means of easy connections. The high frequency poker vibrators provide the necessary balanced combination of high frequency, large amplitude and high acceleration to ensure rapid and reliable compactation.

Our vibrating machines & moulds conforms to 10080 - 1982.
the machine is used for compaction of 70. 6mm 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 r. P. M. 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 power supply.
supplied complete with a time switch, one 70. 6mm i. S. I. Marked cube.
