Code: Aggregate0006 Concrete Test Hammer. Concrete Test Hammer Concrete Test Hammer from Civil Mechanical Laboratory India   Concrete Test Hammer It 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. Concrete Test Hammer for Civil Engineering from Laboratory Equipment Manufacturers India - 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 locks the rider in place and the rider can be recurred to zero position by using the same button. The equivalent compressive strength can be computed from the chart supplied. Each hammer is calibrated against at standard test hammer, and is suitable for specimen of compressive strengths 100 – 700 kg/cm. The instrument, complete with a grinding stone for polishing the test surface, is supplied in carrying case

Pipe surge & water hammer are two related but independent phenomena which arise when fluid flowing in a pipe is accelerated or decelerated. The associated pressure transients can be damaging to pipe work or components and systems must be designed to avoid or withstand them. The equipment designed clearly demonstrates the different effects resulting from gradual or instantaneous changes in fluid velocity (created by slow and fast valve closure). Effect of initial fluid velocity can also be investigated. Pipe surge resulting from a gradual change in fluid velocity is clearly seen as fluctuating changes in head in a surge shaft. Water hammer resulting from a rapid change in fluid velocity is clearly seen as large changes in pressure monitored using a pair of transducers and indicated using an oscilloscope. The equipment comprises two SS pipes connected to a constant head tank. A service module provides the water supply to the head tank and also incorporates a volumetric tank for flow rate measurement, sump tank, circulating pump and flow control valve. Water enters the two test pipes via the constant head tank and discharges into the volumetric tank. A dump valve in the volumetric tank returns the water to the sump tank. The pipe surge test section incorporates a clear acrylic surge shaft to enable visualisation of its oscillatory characteristics to be demonstrated. A metric scale on the shaft permits the height of the oscillations to be measured. The test pipe terminates with a lever operated gate valve and separate flow control valve. The water hammer test section uses a unique fast acting valve specifically designed. Pressure transducers mounted at the fast acting valve itself and at a point along the test pipe provide analogue outputs which are fed into a signal conditioning module. The corresponding output voltage from the signal conditioning module can then be fed into a dual trace oscilloscope. Output is available from the oscilloscope. This allows the stored display to be transferred onto a suitable printer to provide a hard copy of the transient.

Alpha Chem is manufactures,exporter & suppliers Concrete Test Hammer.  Concrete Test Hammer : The Method is based on the principal that the rebound of an elastic mass depends on the hardness of the surface which it strikes. The Test is fast & unlikely to cause damage to the concrete. The hammer is intended for testing the quality of concrete in finished structures such as buildings and bridges. Supplied complete with carrying case and carborundum stone, the hammer is suitable for testing concrete with Compressive Strengths of 10 to 70 N/mm2. Weight 1.4 Kgs. App.

Concrete Test Hammer (Big) For Testing Lab - NAUGRALABS LABORATORY PRODUCT NAME: CONCRETE TEST HAMMER (BIG) FOR TESTING LAB NaugraLabs Laboratory Product Code: NLE-Export-038004 Description and Specification for Lab Tenders It is similar to the above but is used for testing concrete with over size aggregates (for which test, cubes promise no reliable results) and for testing concrete roads.. Cement and Concrete Testing Lab equipment manufacturers,exporters and Cement and Concrete Testing Lab suppliers Its plunger is wider as such, the amount of concrete reached by the impact is considerbly greater. With this model also the results obtained are within 20% of the actual compressive strength. The instrument is supplied with two handles which can be attached to the body of the concrete test hammer for carrying out the test easily. Complete with grinding stones. civil lab equipments manufacturers
