The test procedure specifies a method for determining the change in length of a concrete or mortar sample brought about by a change in moisture content.1. Initial drying shrinkage: the difference between the length of the moulded and cured specimen (under specified conditions), and its final (constant) length when dried. 2. Drying shrinkage: the difference between the length of a matured specimen cut from concrete and saturated, and its final (constant) length when dried. 3. Moisture movement: the difference between the constant length of a specimen when dried, and its length when subsequently saturated with water.

From the measurements it is possible to obtain an estimation of the concrete strength and quality.The method is based on the principle that the rebound of an elastic mass depends on the hardness of the surface which it strikes. The test is fast and unlikely to cause damage to the concrete.Advanced Silver Schmidt Concrete Test HammerProduct Code: 35-1500Product Standards:EN 12504-2 (BS 1881-202), ASTM C805/C805MThe Silver Schmidt ST/PC is the first integrated concrete test hammer featuring true rebound value and unmatched repeatability. Two factors contribute to the improved performance of this concrete test hammer over its predecessors: ±Velocity based detection of the rebound quotient. ±The lightweight hybrid design of the impact plunger made from aerospace alloy, matched to the elastic properties of the concrete and equipped with a hardness steel cap. Independent validation testing by BAM (Federal Institute for Materials Research and Testing, Germany) has shown the Silver Schmidt ST/PC to have less dispersion than the classical concrete test hammer over the entire range. The unique design and high quality construction of the concrete test hammer Silver Schmidt ST/PC makes rebound hammer testing quicker and more accurate than ever before.The Silver Schmidt ST/PC concrete test hammer combines a high measurement accuracy with an unmatched repeatability. ±The rebound value requires no angular correction. The concrete test hammer offers customer conversion curves for a wide range of compressive concrete strengths, including low fc (<10 N/mm2, 1’450 psi) and high strength concrete (up to 100 N/mm2, 14’500 psi). ±A large number of measurement points can be easily collected by the concrete test hammer and automatically evaluated according to statistical data. The concrete test hammer offers automatic conversion to the required measurement unit (MPa, N/mm2, kg/cm2, psi).SpecificationsTechnical DataSilver SchmidtImpact Energy (Nm)2.207Hammer Mass (g)135Spring Constant0.79 N/mmSpring Extension75 mm (2.95 inches)Dimensions55 x 55 x 255 mm (2.16 x 2.16 x 9.84 inches)Concrete Compressive Strengths10-100 N/mm2 (1450 -14500 psi)Weight570 g (1.4 lb)136Non-Destructive Testing of Hardened ConcreteConcretetel: +44 (0)1525 249 200 • email: ele@eleint.co.uk • www.ele.comStandard Concrete Test HammerProduct Code: 35-1480Product Standards:EN 12504-2 (BS 1881-202), ASTM C805/C805MThe hammer is intended for testing the quality of concrete in finished structures such as buildings and bridges.

Some care is necessary when testing, but an experienced operator may obtain a considerable amount of information about a concrete member. The advantage of this method is that the pulse passes through the complete thickness of the concrete so that the significant defects can be detected. Pulse Velocity Measurement can be used for the following applications: ±The measurement of concrete uniformity. ±Determination of the presence or absence of voids, cracks and other imperfections. ±Deterioration of the concrete which might have occurred due to age or through the action of fire, frost or chemical attack. ±Measurement of layer thickness and elastic modulus. ±Determination and monitoring of concrete strength.Pundit LabPundit Lab Ultrasonic Concrete TesterProduct Code: 35-2302/09www.ele.com • email: ele@eleint.co.uk • tel: +44 (0)1525 249 200Product Standards:BS 1881-203, EN 12504-4, ASTM C597Pundit Lab is the most versatile Pundit to date. It has all the functions of the classic Pundit 7, but offers additional benefits. Designed with laboratory use in mind, its compact size, rugged construction and optimised power consumption make it equally suitable for on-site use. Along with the traditional transit time and pulse velocity measurement, Pundit Lab offers path length measurement, perpendicular crack depth measurement and surface velocity measurement. Optimised pulse shaping gives greater transmission range at lower voltage levels.This, coupled with automated combination of the transmitter voltage and the receiver gain, ensures an optimum received signal level for accurate and stable measurements.The waveform can be viewed either via an external oscilloscope connection or directly on a connected PC screen.
