Page 4: Important Safety Information
Important Safety Information GENERAL INFORMATION Basic information The concrete test hammer is designed according to state-of- the-art technology and recognized safety regulations. Please read through these operating instructions carefully upon initial startup. They contain important information about safety, use and maintenance of the concrete test hammer. Designated Use The concrete test hammer is a mechanical device used for performing rapid, nondestructive quality testing on materials in...
Page 5 Important Safety Information SAFETY REGULATIONS General Information • Perform the prescribed maintenance work on schedule. • Carry out a performance check once the maintenance work has been completed. • Handle and dispose of lubricants and cleaning agents responsibly. Unauthorized Operators The concrete test hammer is not allowed to be operated by children and anyone under the influence of alcohol, drugs or pharmaceutical prescriptions.

Page 9 (see Figure 5 to Figure 10, on pages 8-13)Then, using the average rebound value Rm and the selected conversion curve, read off the average compressive strength. IMPORTANT: Note the impact direction! The average compressive strength is subject to a dispersion (± 4.5 N/mm² to ±8 N/mm²).
Page 10 Measuring CONVERSION CURVES Derivation of the conversion Curves The conversion curves (Figure 5, to Figure 10) for the concrete test hammer are based on measurements taken on very many sample cubes. The rebound values R of the sample cubes were measured using the concrete test hammer. Then the compressive strength was ascertained on a pressure testing machine.

Page 17 Measuring FACTORS AFFECTING THE VALUES Direction of impact The measured rebound value R is dependent on the impact direction. Shape coefficient The compressive strength measured in a pressure Testing ma- chine depends on the shape and size of the sample. IMPORTANT: The samples prescribed for use in the Particular country must be taken into account when converting the re- bound value R into Compressive strength.

Page 19 The concrete must be dried before the test. • Very high values for compressive strength (> 70 N/mm²) can be achieved by adding pulverized fuel ash or silica fume. However, these strengths cannot reliably be ascertained using...
Page 20 Measuring Conversion Curves for Special Cases The recommended course in special cases is to prepare a separate conversion curve. • Clamp the sample in a pressure testing machine and apply a preload of about 40kN vertically to the direction in which the concrete had been poured in.

Page 23 Maintenance Long-Term Maintenance We recommend that the concrete test hammer should be checked for wear after 2 years at most and be cleaned. Do this as described below. IMPORTANT: The concrete test hammer can either be sent to a service center authorized by the vendor or it can be maintained by the operator according to the following description.
Page 24 Maintenance • Press the pawl (13) and pull the system vertically up and out of the housing (3). • Lightly strike the impact plunger (1) with the hammer mass (14) to release the impact plunger (1) from the hammer guide bar (7).
Page 25 Maintenance • Slide the hammer guide bar (7) into the hole in the impact plunger (1) and push it further in until noticeable resistance is encountered. Prior to and during installation of the system in the housing (3), make sure that the hammer (14) does not get held by the pawl (13).
