Thermophysical Characterization Of Eco-Plaster Made From Giant Snail Shells

Abstract

The main objective of this work is to carry out the thermophysical characterization of an eco giant snails shells collected in nature. Thermal effusivity and conductivity measurements in transient mode and rate cooling of specimens was carried out. The results obtained showed on one hand that thermal effusivity and conductivity respectively decrease from W.m a comparative study showed on other hand, that density, thermal effusivity and conductivity of synthesized eco plaster are lower than those of shown that temperature rise is the same for both types of plaster up to 15 s in mixin and; up to 30 s for mixing rate of 3.6. Beyond 15 s and 30 s eco-plaster heats up faster than imported plaster. When heat flow is eliminated, we notice that the two plasters are cooled in same way Achatina Achatina. To achieve this, it was first synthesized eco , were then carried out with hot strip method. Finally, a thermal behavior study face to surface heating and 555.386 J.m . K.s . to 377.736 .K to 0.104 W.m.K, when mixing rate increases from 1.8 to 2.7. In the same range of mixing rate, imported plaster. Surface heating tests with a constant heat flow for 180 s have respectively for rates of 1.8 -plaster made from -plaster from snail shells according to mixing J.m . K.s . and from 0.159 - g rate range from 1.8 - 2.7 - 2.7 and 3.6, we note that eco-plaster heats up faster than imported plaster. When heat flow is eliminated, we notice that the two plasters are cooled in same way.
