Cement Composites Reinforced With Sheep’s Wool

Sustainability issues have become prevalent in the past years especially in sustainable construction practices which are both ecologically friendly and also cost efficient as they are often based on the utilization of available end-of-life materials. This paper describes a research on the use of a new construction material composed of cement and natural fibres obtained from sheep’s wool. Low grade sheep wool has no use and needs to be disposed of and that costs money together with several serious problems created by its safe utilization. There are about 90 million sheep in the EU, producing 270.000- tons of wool. An estimated 10% is low grade coarse wool and needs to be disposed. Within presented research, sheep’s wool is utilized in cement and lime based mortar mixtures to be used for rendering of interior wall surfaces. The aim of the research was to experimentally quantify and to compare the performance of natural sheep’s wool fibres in low strength mortar. Developing a mortar mix design enhanced through the addition of natural sheep’s wool fibres, together with quantifying and analysing mechanical, physical and thermal properties of such cement and lime based mortar are the topics of this research.
