FIELD: testing equipment.
SUBSTANCE: invention is related to testing equipment, namely to instruments for strength testing of construction materials. Instrument for strength testing of construction materials comprises unit for installation of sample, loading device with drive and device for measurement of load, which are installed in power frame. Two elastic elements of various pliancy are installed serially with sample, besides one of them, for instance in the form of spring, is installed between sample and drive that deforms it with a certain rate, and the other detector of load measurement, with lower pliancy, is installed between sample and base of power frame.
EFFECT: increased accuracy and reproducibility of test results, improved efficiency of instrument and expansion of its application field.
