Dynamic Modulus of Elasticity of Dental Gypsum

Popis výsledku v původním jazyce

The paper describes the influence of water/gypsum ratio to the dynamic modulus of elasticity of dental gypsum. Commercially available dental gypsum Interdent? (with compressive strength 250 MPa after 24 hours) was used in our study. It was assumed that water to gypsum (w/g) ratio would have influence on its mechanical properties. Therefore, five different types of specimens with w/g=0.18, 0.19, 0.20, 021 and 0.22, further denoted as G0, G1, G2, G3 and G4, were prepared. These samples were tested using nondestructive method. The dynamic modulus of elasticity was determined based on measured basic resonant frequency of longitudinal vibration of the specimens. At the end, the comparison of obtained values in dependence on water/gypsum ratio was done.
