Influence of Freeze-Thaw Cycles on Mechanical Properties of Gypsum Determined Using the Impulse Excitation Method

Original language description

Non-destructive methods for testing mechanical properties of materials spreads to many fields of investigation at present. A typical example of the use of non-destructive testing can be determination of the effect of freeze-thaw cycles on the mechanicalproperties of porous building materials. The great advantage of non-destructive testing, compared to destructive, is that still the same sample is tested and it excludes various negative effects such as technological indiscipline in the production of samples, different environment storage of samples prior to testing, recognition of cracks in the sample prior to testing, etc. The paper presents the development of modulus of elasticity on samples of hardened plaster according to the number of freeze-thawcycles. Elastic moduli were determined using an impulse excitation method. For cyclic loading, the samples were saturated with water at 20 °C and tested in 8-hour cycles. Samples were removed from the water bath and placed in a freezer wi
