In this study, engineering features of insulation materials produced from egg
white, perlite, gypsum and fly ash were investigated. Densities, water
absorption ratios, ultrasonic velocities and thermal conductivity
coefficients of samples were determined. Furthermore, linear absorption
coefficient were measured by gamma ray saturation levels at 17.7, 26 and 60
keV energies. Thermal conductivity coefficients of the produced composites
were found to be in the range 0.0882- 0.0995 Kcal/mh?C. Egg white decreased
the linear absorption coefficients. Unit weights of samples were found to be
dependent on their contents. As gypsum rate increased, unit weight also
increased. As perlite rate increased thermal conductivity coefficient
decreased. As egg white decreased the linear absorption coefficient
decreased, also. The most important benefits of these types of materials are
their being impermeable and perfectly compatible with the environment. These
lighter type materials were/are compatible with Turkey and the Middle East
environment. Egg white has been resistant to radiation. Hence, it is highly
compatible with the environment. The compressive and flexural strengths of
mortars decreased with the use of egg whites in mortar. So, egg white
enhances the binding property of samples. In most cases, some organic and/or
inorganic additives are used as well, to improve the physical and mechanical
properties of mortar, such as egg whites and others. Finally, this study
shows that it is possible to produce an insulation material resistant to
sound and radiation by using egg white, perlite and fly ash. It is seen that
the samples incorporating egg white could be used at hospitals, military and
industrial facilities and shelters which are under radiation hazard.
Furthermore, this insulation materials will be put to use in industry in
Turkey after many experiments have been done on laboratory.
