Development of technology for foaming keratin based on sheep's wool

Abstract

The purpose of this article is to evaluate the effect of wool fibers on the thermal conductivity and mechanical properties of cement. The use of sheep's wool as a cement admixture for the production of mortar or plaster provides a number of advantages for the environment and the energy sector. Moreover, in some regions of the country, it is considered as a waste, therefore, its use is characterized by a low cost. Currently, synthetic materials that do not ensure the stability of the foam mass, adversely affect the strength of cellular concrete and do not allow to obtain high-quality concrete with the specified physical and mechanical properties prevail. The use of protein foaming agents, characterized by high quality indicators, environmental cleanliness and production safety, is becoming more and more popular.
