| Summary: | In the last decades, eco-friendly materials have become an important part of the building materials market. Particularly, many studies deal with the use of natural fibres as replacement to synthetic fibres in reinforced composites. Natural fibres are already used in various types of materials, like plastics, concrete and lime- based products. They demonstrate different attributes such as good mechanical, thermal and acoustic properties, low cost, low density and recyclability that allow these types of materials to be used for different applications.
As the most abundant component in wood and most plants, cellulose is an almost inexhaustible polymeric raw material from renewable sources. Using of natural cellulosic fibres as reinforcing components in building materials is constantly growing and can play a leading role in this transition toward renewable materials, which also promotes a healthy and comfortable style of housing.
In this work two types of plasters based on waste cellulosic fibres coming from different biomass resources were prepared and analysed to evaluate the influence on their performance of different fibres used as reinforcement.
In particular each plaster was realised by adding to the mortar the same amount of recycled fibres from waste paper and hemp (Cannabis Sativa) hurds as a woody core of hemp plant coming from hemp stem processing. This paper deals with characterization of morphology, chemical composition and structure of cellulosic fibres coming from various sources. Subsequently, physico-mechanical characteristics of plasters were also investigated.
