THERMAL BEHAVIOUR OF DIFFERENT CELLULOSE RENEWABLE RAW MATERIALS

The construction and manufacturing industries search for innovative materials that are sustainable, reliable and can replace conventional synthetic fibres. At present, there is a growing interest in renewable material based on cellulose fibres. These cellulose fibres can be obtained from numerous resources namely agriculture, construction and many others sectors of industry (e.g. paper mill). Natural fibres as reinforcement into concrete have a great interest in new technologies dealing with environmental aspect. The use of cellulose fibres in cementitious matrices have gained prominence because they make the composites lighter, they have comparable cost-performance ratios to similar building materials and they could be processed from waste paper, thus expanding the opportunities for waste utilization in cementitious materials. Application of cellulosic fibres into composites depends on their properties. Thermal stability of cellulosic fibres is one of the important properties of physico-chemical nature of these fibres determining their commercial significance. In the present work, thermal behaviour of cellulose samples from wood pulp and waste paper is studied in order to propose their potential utilization and application in building materials.
