摘要：

A non-destructive process, using ultrasonic techniques, for evaluating the elastic properties of a material is applied to a series of metakaolin based geopolymers with Si:AI ratios ranging from 1.49 to 6.4. This study evaluates the speed of sound of both a shear and longitudinal ultrasonic wave for each sample as well as the density's relationship to the Si:Al ratio. The trends observed for the Poison's ratio, elastic modulus, and speeds of sound showed a discontinuity around a Si:Al ratio of 3.1:1 supposedly due to the chemical changes between the poly(sialate-siloxo) (PSS) and poly(sialate-disiloxo) (PSDS) regions. Within the PSS region, the elastic modulus and Poison's ratio decreased linearly as the Si:Al ratio was increased. The trends within the PSDS region were discontinuous from the previous trends but not enough data was collected to sufficiently describe them.
