ULTRASONIC DETERMINATION OF ELASTIC MODULUS OF MARBLES RELATION WITH POROSITY AND CaO
نویسندگان
چکیده
Since ancient Greek times marble has been used for decoration and for sculpture. In this paper, we have analyzed marble samples, which were selected according to their porosity and the proportion of CaO values, with ultrasonic velocity measurement methods. Elastic modulus was evaluated from longitudinal and transverse velocity of ultrasonic wave propagation in marble samples. Our results indicate that the elastic modulus shows linear dependence to the porosity and the proportion of CaO. The correlation factor of fitted line is about 0.9. Also the longitudinal velocity shows more linearity than the transverse velocity.

Production of highly porous composite materials by traditional materials processing is limited by difficult processing techniques. This work investigates the use of self propagating high temperature (combustion) synthesis (SHS) to create porous tricalcium phosphate (Ca3(PO4)2), TiB-Ti, and NiTi in low and microgravity. Combustion synthesis provides the ability to use set processing parameters t...
