Abstract
The purpose of this paper is to characterize a novel composite material based on natural components. The studied composite is a lime based mortar, formulated with hydrated lime, rice paste and sheep wool fibres. The assessed properties of the mortar are the following: adherence to the support layer, thermal conductivity, thermal resistance, and acoustic absorption. Based on the obtained results, it can be stated that the proposed composite material has an acceptable adhesive strength (0.125 N/mm2), low thermal conductivity (0.157 W/mK) and high acoustic absorption at high frequencies (0.93 at 2360 Hz). Considering the obtained values for the mechanical, thermal, and acoustical properties the studied composite could be used in the field of constructions as interior finishing.
