Properties of Lightweight Thermal Insulation Plasters

Abstract:

The design of thermal insulation plasters is closely connected with their apparent density and the binder used where low apparent density may fetch very good thermal insulation properties. What matters is the correct composition of the plaster mix system being designed. The choice of binder, other components and especially aggregate taking up a dominant part in the system is also important. A suitable aggregate is expanded obsidian which has very low density with open pore structure which has positive influence on thermal insulation properties.
