Although generally not such an important property of concrete than compressive strength, tensile strength values are often important to know when the concrete used free of reinforcement and may be subjected to some tensile force. The test method essentially involves applying a load at the centre of a beam of concrete supported at its ends. The load required to break the specimen is then recorded.

air content of fresh concrete is normally measured, by the use of a special air meter, to assess whether the concrete contains the required amount of air. This would be measured when airs entrapment or entrainment is required by the concrete design. The method uses the principle of replacing the air in a known volume of concrete with water, the volume of which can then be measured.
general descripation & specificationsthe apparatus consists of a pressure tight flanged cylindrical measuring bowl of specified volume in accordance with size of aggregate to be tested. The bowl is fitted with a removable flanged conical cover assembly with the help of a airtight sealing gasket. The conical cover has an air valve and a pet cock for bleeding off the water. A transparent cylindrical stand pipe, which is graduated in air content, is fixed to the conical cover assembly.
pressure is applied to the specimen with the help of pressure bulb and the pressure is recorded on the pressure gauge which is mounted on the stand pipe. The whole assembly is mounted on a flat base.

Often, existing concrete structures will need to be examined and tested to ensure the concrete remains of adequate strength and durability. Rebound hammer surveys can be conducted to provide a rough estimate of concrete strength, where it is not possible to determine this by more accurate means such as core extraction and testing.
The test involves using a special rebound hammer, which measures the recoil of a piston against the concrete surface when a standard force is applied. This recoil can then be correlated approximately to concrete strength.
General Description & SpecificationsThe rebound hammer consists of a barrel in which is housed a hammer mass attached to an impact spring which slides on a guide bar. A plunger is attached to the guide bar which is pressed against the surface to be tested. As the piston is pressed against the surface to be tested, on reaching the compressive strength, the hammer mass is released and rebounds to a certain extent, according to the strength of the surface, which is indicated by a rider on a calibrated scale. A lock button fixed on the body of the hammer lock the rider in place and the rider can be reset to zero Position by using the same button. The equivalent compressive strength can be computed from the chart supplied. It is suitable for specimen of compressive strengths 100-700Kg/cm. The instrument, complete with a grinding stone for polishing the test surface, is supplied in carrying case.
Hydraulic Jacks are of multipurpose utility i.e. application of loads while engaged in field investigation, determination of load carrying capacity of piles in the field, tensioning of wires in pre-cast structures, loading of members of any structures for deformation characteristics. For applying loads for various test in field or laboratory. Hydraulic Jack hand operated with separate pumping units. These jacks are portable available in various capacities. The pumping unit is connected to the hydraulic jack by means of a flexible connecting pipe 2 meter long. The jack is fitted with lifting handles for easy transportation. The approximate lift of the ram is 90 to 120 mm. The pumping unit is a single plunger type with detachable handle. The unit is fixed on a channeled base which is fitted with lifting handles. A pressure release valve is provided on the pumping unit. The load is indicated on a 15 cm dial hydraulic pressure gauge of appropriate capacity which can be detached from the pump when not in use. The least count of the calibrated dial will be according to the capacity of the gauge (Normally 100 divisions for full capacity). Lift of ram - 150 mm.
In the process of compaction, efforts are only directed to reduce voids in the compacted concrete. The Vibrators produce vibrations which when transmitted to plastic concrete make it to flow and affect compaction. The air bubbles are forced out of concrete due to vibrations.
The Needle Vibrator, also known as immersion or poker vibrator have a power unit and long flexible tube at the end of which a vibrating head is attached. Wherever compaction is to be done, the vibrating head is inserted in the concrete.
The Laboratory needle vibrator having 350mm long X 25mm dia Needle is used in vibrating concrete test cylinders and beams in the field or laboratory. It is also widely used in making laboratory specimens, in making concrete products, in experimental works, and in small scale construction project. It has 1 meter long flexible shaft and is powered by 1 HP single Phase Electric motor.
The Needle vibrator for compaction of mass concrete has 40 or 60mm dia needle with 6 meter long flexible shaft and powered by 3 HP Electric motor for operation on 440 Volts, 3 phase, 50 cycles, A.C. Supply. Optionally, the Vibrator can also be fitted with Petrol/kerosene or Diesel Engine for field use.

The tile sample is pressed under a specified load against a grinding path strewn evenly with an abrasive powder revolving at the rate of 30 + 1 r.p.m. At the end of 100 revolutions of the disc the second parallel side of the tile is subjected to wear for an equal number of revolutions of the disc. The wear of tile is measured using a thickness gauge. The Abrasion testing machine consists of a replaceable grinding path fitting on to a disc rotating its vertical axis. The rotating disc and grinding path are enclosed by a circular tray. A bracket holds the specimen. The loading is by a counter balanced lever. A funnel is provided to facilitate charging the grinding path with abrasive powder.

The Veebe consistometer measures the remolding ability of concrete under vibration. The test results reflect the amount of energy required to remold a quantity of concrete under given vibration conditions. The Veebe consistometer is applicable to concrete with slumps less than 2 inches.
The apparatus, consists of a metal cylindrical container mounted on a vibrating table, which produces a sinusoidal vibration, a slump cone is placed in the center of the cylinder and filled in the same manner as in the standard slump test. After the slump cone is removed, a clear plastic disk is set atop the fresh concrete. The Veebe table is started and the time for the concrete to remold from the slump cone shape to the shape of the outer cylindrical container is recorded as a measure of consistency. The sliding clear plastic disk facilitates the determination of the end of the test.

Cubes of fresh concrete are made to test a variety of properties on the eventually cured and hardened concrete. Fresh concrete is subjected to a standard compaction regime in the cube mould and is then normally initially cured under specific laboratory conditions. The moulds are manufactured, subject to tight dimensional, hardness, square ness and surface finish requirements.
