The device for testing of mechanical properties of building materials IPM-1A

        Nondestructive testing of hardness and strength of asphalts, concretes and other building materials (hardened bitumen, bricks, etc.). Also the device allows estimating mechanical characteristics of a material in samples and articles (dynamic elastic modulus, viscosity, etc.), find heterogeneous zones or zones of bad consolidation.
        The device is based on dynamic indentation method - local impact loading of the material tested, recording of the analog signal of indenter velocity, its analog-to-digital conversion and calculation of the mechanical characteristics of the material tested, using special algorithms.
        Installation IPM-1A is made as the two separate units: impact gauge and electronic module, which must be connected to personal computer. Using of PC for data processing allows obtaining more detailed information about the material deformation process (impact duration, maximum penetration depth, maximum contact force, restitution coefficient of indenter velocity).
        - High self-descriptiveness. By the result of one test impact user gets information about elastic, plastic and viscous properties of a material under test.
        - Expanded measuring range allows testing both asphalts having strength less then 1 MPa and high-strength concrete (more the 60 MPa) using the same device.
        - Sufficiently high impact energy (1,5 J), which allows decreasing data scattering caused by material heterogeneous.
