Newsprint as the input raw material for the production of fibers, usable in civil engineering

Original language description

Recently the consumption of paper ceased to increase as rapidly in the Czech Republic, as opposed to previous decades, nevertheless, the main area of paper usage is changing. It is a very important part segment of handbills, flyers, brochures, newspapers and other printed materials which can be difficult to reuse at the end of their lifetime. It is possible to recycle predominantly natural fibers with desirable parameters by means of suitable technology of processing these cellulose materials. This paper describes the possible use of these fibers as lightweight, natural fiber reinforcement in composite materials. Specifically, it describes the results of work aimed at the development of thermal insulating plasters containing recycled fibers. Experts from the Brno University of Technology, Faculty of Civil Engineering have concerned themselves with the development of lightweight plasters for many years. Recycled fibers based on cellulose were used in mixtures of previously designed plasters, given the still unsatisfactory results in terms of the mechanical properties of the materials. Their main function was to improve the mechanical properties and prevent any shrinkage of the plasters and subsequent formation of micro cracks. The aim of the research was to obtain lightweight plasters with good thermal insulation and mechanical properties. It can be observed, based on evaluation of the research, that the application of waste cellulose fibers in lightweight, thermal insulation plasters significantly improved the workability of fresh mortars in comparison with the mortars of the same composition but without the addition of reinforcing fibers. It was discovered, upon comparison of mechanical properties of the reference mixture without fibers and mixtures containing cellulose fibers that the compressive strength increases by up to 192 %, the tensile strength was found to be up to 150 % higher.
