Product DescriptionThe strength of concrete is generally estimated after 28 days by crushing field test cubes or cylinders made from the representative concrete used for the structure. The utility of ascertaining strength after 28 days is often questioned since by this time considerable concrete would have been placed and work may have progressed. It is then rather too late for remedial measures. It is therefore of tremendous advantage to predict 28 days strength within a few hours of casting the concrete so that, we have a good idea about the strength of the concrete. The rate of gain of strength of concrete depends on the reaction rate of cement and additions with water (Hydration). In common with all chemical reactions, the rate of reaction depends on reaction of temp. Higher reaction temperature gives higher rate of reaction e.g. the concrete gains strength more rapidly when its temp. is higher. Accelerated curing is the process by which the temperature of the concrete is raised artificially by applying external heat to speed up the rate of gain in strength. The test method covers procedures for curing test specimens of concrete stored under conditions intended to accelerate the development of strength. The procedures are: Procedure A- Warm Water Method, Procedure B-Boiling Water Method


General Description & Specification:
Accelerated Curing Tank having capacity to accommodate 6/12/18 Concrete Cubes of 150mm size with a facility for accelerated curing by Boiling water method up to temperature range : 100 +/- 2 deg.C as per IS standard IS : 9013. Also it will have capacity for curing by warm water method at temperature 55 +/- 2 deg.C
Tank will consist of a rectangular double walled metal cabinet, inside lined with stainless steel, outer powder coated. Easily replaceable high Wattage heaters are mounted in side the chamber. A slow speed stirrer is provided to circulate water inside the chamber to maintain the uniform temperature of water. A strong stainless steel perforated platform is provided for keeping the cubes and also have a lid with lifting handle to cover the chamber.
The temperature is indicated and controlled by a DIGITAL auto tuning PID Temp. Controller with soak timer to control the duration of heating and then to shut down the system without manual attendance. The front panel will have power supply indicating lamp, control action indication lamp and one main switch. Suitable for operation on 220 V, 50 Hz single phase, AC supply or 440 V 50 Hz, three phase AC supply, for bigger size of curing tank.

    The fineness of cement has a significant effect in its physical properties when used in concrete. Generally the finer the cement powder, the more rapid the concrete will set, as there is an increase in its surface area. The measure of fineness is usually undertaken by sieving, and the result assessed against the cement standard for compliance. The Blaine air permeability apparatus is used to determine the fineness of Portland cement in terms of the specific surface expressed as total surface area in square centimeters per gram of cement. The Blaine apparatus draws a defined volume of air through a prepared bed of cement of defined porosity.


    General Description & Specification:
    The apparatus comprises one each of Brass or stainless steel permeability cell 12.5mm,’U’ tube manometer with stop cock mounted on a laminated wooden stand, perforated metal disc, plunger, Rubber stopper, Rubber tube – 30cm long with rubber bulb.

    After it has set, cement must not undergo any appreciable expansion, which could disrupt a mortar or concrete. This property of soundness is tested by subjecting the set cement to boiling in water or to high-pressure steam. Unsoundness can arise from the presence in the cement of too much free magnesia or hard-burned free lime. This method covers determination of the autoclave expansion of Portland cement by means of a test of neat cement paste specimens, 25.4 X 25.4 X 285.8mm, which are moist cured for 24 hours +/- 1-1/2 hours and then exposed to action of steam under specified pressure for 3 hours. The rate at which pressure is increased in the beginning the test and released in the test are specified. Linear expansion is measured by micrometer comparator.

    • Rust proof stainless steel pressure vessel
    • Specially designed Steam Safety Valve, pressure control switch and Temp. control switch – Triple Safety precautions for operator safety
    • Accurately Calibrated Pressure Gauge
    • Guaranteed timings and performance as per IS 4031


    General Descripation & Specifications:
    The Autoclave is double walled. Inner boiler chamber of stainless steel cylinder, with concealed yet easily replaceable heaters surrounding the vessel for quick heating. The boiler lid is of thick stainless steel and can be bolted to the chamber by heavy hexagonal nuts. The silicon gasket, seated in a groove, makes the unit leak proof even at high pressure. The boiler is mounted in between the strong angle iron frame and covered with CRC sheet – attractively powder coated. The outer cover can also be of Stainless steel at an extra cost. The gap in between the walls is filled with thermal insulation to prevent heat loss and energy. The control system consist of sensitive pressure regulator, pressure gauge, safety valve, temperature control switch, power ON-OFF switch and pilot lights to indicate status of the electric heating units and control switches.

    Laboratory Pulverizer is a disc type grinder, designed to grind virtually any material to produce a fine mesh sample in one operation. It is a self contained grinder, with a rotary disc, having a planetary movement in a vertical plane. This feature gives added life to the moving parts and produces a sample of uniform fineness. Grinding is done between two discs, one of which is stationary and the other revolving eccentrically at high speed. The discs are made from heat treated mechanite metal. With the help of a convenient hand wheel, the six of the final product can be adjusted. This can be done, even while the machine is in operation.

    Product DescriptionVicat Needle Apparatus is used to determine the amount of water required to produce a cement paste of standard consistency and the setting time. The time it takes for a cement to stiffen to a standard value after addition of water is commonly known as the set time. The test involves mixing cement with water and then measuring its resistance to penetration of a standard probe at varying intervals of time, until a certain value is reached.

    Specifications:

    • Consist of a metallic frame bearing a movable rod with cap at one end. The needles and plunger can be fixed centrally in to the rod by clamping screw. The movable rod carries an indicator which moves over a graduated scale attached to the frame. The scale is 40mm in length with the smallest division of 1mm. The dashpot facilitates the gentle lowering of the movable rod with needle.
    • The vicat moulds can be in the form of frustum of a cone having 70 mm in dia at the base, 60 mm at the top and 40 mm high or split type. A non porous base plate of glass or metal also provided. Complete with consistency plunger, initial and final setting needles in a nice jewellery case.
