Cement & Concrete Testing Equipments

We make available to our valued clients Blaine Air Permeability Test App. that provides a significant effect in the physical properties of concrete. For increasing the surface area, the finer cement powder is required for effective setting of the concrete. The fineness of the cement is measured by sieving and the result is assessed against the standards cement. Besides, it is used to determine the fineness of Portland cement on the basis of the specific surface that is expressed as total surface area in square centimeters per gram of cement. The Blaine apparatus draws a well-defined volume of air through a prepared bed of cement of the defined porosity.

High quality Slump Test App. is used for determining workability. This test helps in determining the workability of fresh concrete that can be normally undertaken at the point of delivery to assure that the concrete is of appropriate consistency for placement. The test is applicable to concrete of medium workability and the device is a type of hollow cone-shaped mold. The mold is generally filled in three layers of every volume and is rodded with a 16 mm steel rod for 25 times. The mould is then easily lifted away and diversity in the height of the concrete is generally measured against the mould. The slump test is a type of measure for checking the resistance of concrete to flow under its own weight.

Our organization is engaged in offering Flow Table that is suitable for concrete mixes of high and very high workability. The consistency and workability of the concrete is connected to the water and cement ratio, to ensure the effect of admixtures and finally to the strength and quality of concrete. To perform this test, a sample of the concrete is placed on a metal surface that is raised and dropped for a known height.

Our organization is engaged in providing Ball Mill that is robust in construction, resistance to corrosion and possesses high operational life. This mill consists of a drum that is made of welded steel and have an inside diameter of length 300mm x 300mm. IT is supported by heavy duty bearings and also a reduction gear that is driven by a motor, which rotates the ball mill at 28-30 PM. Furthermore, it is supplied complete with 12-19mm dia steel balls and revolution counter.

We offer our clients Air Entrainment Meter that is used for measuring air content of fresh concrete. These meters make use of special air meter for assessing if the concrete contains the requisite amount of air. Besides, these meters are measures air's entrapment or entrainment that is required by the concrete design. This method uses the principle of replacing the air in a known volume of concrete along with water for measuring the volume of water.

We offer our clients wide array of Accelerated Curing Tank that is used for measuring the strength of concrete. The strength of the concrete is generally estimated only after 28 days by crushing the field test cubes or cylinders, which is made from the representative concrete generally used for the structure. Accelerated Curing Tank reduces this long period of 28 days and therefore is highly appreciated in the market. Following are some of the details of these tanks:

• The rate of gain of strength of concrete is dependant on the reaction rate of the cement and additions of it with water (Hydration) that is in common with all the chemical reactions
• the rate of reaction depends on reaction of temp.
• Higher reaction temperature gives higher rate of reaction such that the concrete gains strength more rapidly when its temp. is higher
• Accelerated curing is the process in which the temperature of the concrete is raised artificially by using external heat to maximize up the rate of gain in strength

We put forth for our clients Cement Auto Clave that is highly acclaimed for superior quality, accurate results and longer functional life. This clave are integrated with hi-tech instruments as per the set industry standards. Furthermore, these calves are available in varied sizes and specifications to go well with the requirements of the clients. Following are the working process of this clave:

• The property of soundness is an appreciable expansion, which could disrupt a mortar or concrete, is tested by subjecting the set cement to boiling in water or to high-pressure steam
• This method covers determination of the autoclave expansion of Portland cement by means of a test of neat cement paste specimens are 25.4 X 25.4 X 285.8mm, which are moist and cured for 24 hours +/- 1-1/2 hours and then exposed to action of steam under a specified pressure for 3 hours
• The rate at which the pressure is increased in the beginning of the test and released in the test are specified
• Linear expansion is measured by micrometer comparator

Body made of thick PCRC sheet-power coated or stainless steel (S.S.304).Top plate made of heavy C.I. or stainless steel and is fitted with the body in such a way that, the body gets minimum heat while the top plate is fully heated. Supplied complete with pilot indicating lamps, power plug and cord wire to work on 220/230 AC, Single phase. With three heat control switch and energy regulator.

Double walled, inside chamber stainless steel, outer body made of CRC/G.I. - powder coated, Temp. Range from ambient +5° C to 60° C controlled by Dual Display Microprocessor based Digital Temp. Controller with +/- 0.5° accuracy, Humidity range from atmospheric humidity to 95 % controlled by Dual display Microprocessor based Digital Temp. Controller (Dry and Wet bulb method) with + 3 % RH. Inner water tank made of stainless steel with ball cock valve. Front door has a full view glass observation window.

We provide our clients Flexural Testing Machine that is highly demanded for compressive strength and high tensile strength values. These testing machines helps in knowing when the concrete is used free of reinforcement and can be subjected to certain tensile force. The test method involves applying a load at the main center of the beam of concrete supports at its ends. The load required for breaking the specimen is then recorded.

Vibrating Machines offered by us are used for the preparation of mortar cubes for determination of compression strength of ordinary and rapid hardening Portland cement, low heat Portland cement, Portland blast furnace cement and high alumina cements. This machine is an easy method is to provide greater vibration of lower amplitude to the mold while casting. Besides, air tapped in cement mortar paste cannot be easily removed while casting cement mortar moulds.
