ROLE OF FIBER IN THE ORGANIZATION OF THE STRUCTURE OF MATERIAL ON THE LEVEL OF PRODUCTS

Abstract

The article proposes to consider architectural products in the form of decorative material decorated in certain geometric frames. In order to obtain an operational-reliable material for products of complex shape, it is proposed to use reinforcement of the composite structure. Previous studies on the nature of the influence of fiber on the processes of organization of structures at the micro level of the material showed an active, peculiar and unique role of linear elements. The results of structural parameters of cement compositions presented in this paper are a continuation of previous studies. For the study of structural parameters, models of decorative elements of various shapes are taken as objects. Models were made on the basis of water-clays, water-cement and epoxy compositions. To assess the effect of linear elements, fiber of different lengths and hybrid mixtures were used. When conducting experiments on models, the change in volume mass over time, relative shrinkage, material’ damage through to the value of the damage coefficient were determined. To assess the distribution of residual deformations, a graphoanalytic method and a photoelasticity method were used. Experiments on the organization of the structure of models of decorative elements of various shapes confirmed that the distribution of deformations is determined by the geometric parameters of the products. It is established that the use of fiber changes the mechanisms of organization of integral structures of products. The active participation of fiber in the organization of the structure of products gives grounds to consider it not only as a reinforcing’ components of the structure, but also an equal component of decorative materials with a directed purpose - to regulate and manage the processes of structure formation at all levels of structural heterogeneities of the material. Dispersed-reinforced structures formed under the influence of fiber change the damage of the material, perceive and dissipate volumetric integral deformations.
