Concrete Test Hammer Dealers in Delhi

An increasing number of contractual obligations call for various forms of vibro- compacted concrete for achieving a better and more consistent mixture. The needle vibrator is recommended for vibro- compaction of test cylinders and beams at site and in the laboratory. This instrument can also be used at small construction sites. A motor fitted on a swivel base drives a flexible shaft, which in turn, vibrates the needle at about 10,000 vibrations per minute. (approx. ) Salient Features Specifications : 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. 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 recared 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.

This is intended for non-destructive testing of the quality of concrete in finished structures. In testing, the rebound number is measured, which is dependent on the strength of the mortar (concrete with coarse particles) close to the surface. Since the strength of the mortar as a rule determines the strength of the concrete, the rebound number gives an indication for the strength of the concrete. The results obtained are ±15% of the actual compressive strength. As the test does not destroy the specimen, the curing process continuing after setting of concrete the be followed up accurately.

The quality of concrete is mainly judged by its compressive strength directly affecting the load-bearing capacity and durability of concrete structures. Proceq invented the Original Schmidt, the world’s first and now most widely used test hammer for analyzing the compressive strength of concrete properties. The Original Schmidt will hit the concrete at a defined energy whereas its rebound is dependent on the hardness of the concrete and is measured by the instrument. The Original Schmidt is available in models with different impact energies, each test hammer designed for a specific test application, in order to meet the needs of the customers to investigate a wide range of material types and sizes, such as bridge decks, thin walls, cast stone components or small components.

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. The 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.

Aggregate is consisted by a majority of materials of construction, and it is common practice to test aggregates for properties. Some properties like particle size, distribution, relative densities, soundness and resistance to attack by chemicals are checked. Sampling of aggregates forms an obligatory fraction of several constructioncivil engineering projects. Getting the sample to gauge the average quality of the entire mass is of prime importance. It is also true that some properties may perhaps be ideal in one situation, but not in another. S.S.International presents a fine array of cutting -edge and sophisticated aggregate testing instruments which are extremely dependable and guarantee complete accuracy of the operations. It is generally employed for sampling and preparation, abrasion value and tile testing. Grid Sieves, Riffle Boxes, Wire Basket, drying shrinkage and Aggregate Crushing Value Apparatus are some of the aggregate testing equipments from our side.

kEWIL Concrete Test Hammer Useful for non-destructive estimation of quality of concrete of a finished structure and its relative compressive strength. The instrument consists of a casing in which a hammer mass, special spring, hammer locking and release mechanism are housed. A spherical ended plunger projects at one end which, when pressed against the test surface, actuates the release mechanism of the hammer mass. It gives an impact on the plunger. The hammer mass rebounds after the impact and an indicator registers the amount of rebound on a linear scale. The compressive strength of the material can be computed from the calibration diagram supplied with each hammer. It gives results within +15% of actual compressive compressive strength.

The rebound of an elastic mass depends on the hardness of the surface against which its mass strikes. When the plunger of the rebound hammer is pressed against the surface of the concrete, the Spring-controlled mass rebounds and the extent of such a rebound depends upon the surface hardness of the concrete. The surface hardness and therefore the rebound is taken to be related to the compressive strength of the concrete. The rebound value is read from a graduated scale and is designated as the rebound number or rebound index. The compressive strength can be read directly from the graph provided on the body of the hammer.
