Measurement of physical properties of polyurethane plaster

Jan Valíček, Marta Harničárová, Milena Kušnerová

Abstract

Physical properties of building materials can be defined by material coefficients. The material coefficients examined were: coefficient of mean density, coefficient of specific heat capacity, coefficient of thermal conductivity, and coefficient of thermal diffusivity. Physical properties of a newly-developed material (polyurethane plaster), were subjected to non-destructive analysis. The same method and same conditions of measurement were applied to measure the properties of comparative samples made of Ytong. In order to measure the coefficient of thermal conductivity and coefficient of thermal capacity, a new comparative method was designed and verified and also a new calorimetric apparatus was used.

Keywords
polyurethane plaster, new method of measurement, specific heat capacity, thermal conductivity, thermal diffusivity
