Utilization of Lavender Waste in Traditional Mortars
It is well known that the most effective method to improve the internal tensile strength of lime-based mortar and minimize plastic shrinkage is the incorporation of fibres as reinforcement. Nowadays, commonly used fibres in lime-based mortars are polymeric or synthetic ones, while only recently the building industry’s current trend to develop sustainable materials, brought natural fibres to the forefront. Natural fibres are abundant, low-cost, renewable, with a CO2-neutral life cycle and high filling levels possible, sustainable, energy efficient, biodegradable, non-toxic, of nonabrasive nature, of low weight and density, yielding lightweight composites of low environmental footprint. In this sense, the current research aims to examine the possibility of utilization the solid lignocellulosic waste material generated from the lavender oil extraction plants in lime-based mortars. The lavender fibres were introduced in two ways: as additives in 1.5% b.v. of the mortar and as a layer (net) between two mortar layers. Both techniques were often met in historic structures. Specimens were produced to examine the mechanical, thermal, physical and microstructure characteristics of the composites. The results indicate the utilization potential of aromatic plants’ wastes in the building sector contributing to the development of sustainable and energy efficient materials suitable for repair works.
