THE RESEARCH OF PROPERTIES OF COMPOSITE MATERIALS BASED ON PLASTER WITH REINFORCEMENT OF NATURAL FIBRES
Abstract
The plaster is one of the most often used materials in the civil engineering. It is applied in the form of plasterboards without any reinforcement, for example, cladding boards are unusable as supporting construction. To improve the mechanical properties of plasterboards, fibrous materials such as cellulose or glass fibre are added. The main purpose of the research is to clarify whether natural hemp fibres or straw could be used as the reinforced materials. The second purpose is to verify the use of non-standard types of natural materials such as starch. The research explores the impact of the natural fibre on mechanical properties of the plasterboards (compressive strength, tensile strength, flexural strength). Also, there is determined the most suitable type of binders in production technologies of reinforced composite materials and its mechanical properties, for example, shape, length and amount of fibres, are tested. Finally, the research deals with the mechanical, fire, acoustic and thermal properties of the examined materials.
