Abstract
The article presents the results of studies of the influence of alkali-resistant glass fibers of different lengths on the functional properties of decorative concrete. It is based on the data of an experiment carried out according to the optimal unsaturated plan, which includes 27 different compositions of the material. The combinations of the decorative compositions had equal mobility of the mixture, with the minimum and maximum water-cement ratio of 0.36 and 0.55, respectively. Based on the results of the experiment, the primary experimental-statistical models describing the effect of composition factors on the properties of the material made it possible to reveal that an increase in the level of plasticization of the compositions allows to increase the utilization factor of the strength of glass fibers. The efficiency of hybrid reinforcement of decorative composites with glass monofilaments has been confirmed through the implementation of a number of computational experiments (CE). The analysis of the CE results showed that the introduction of hybrid highly dispersed fibers into the initial composition of polystructural decorative concrete, with their different quantitative combinations, makes it possible to improve a number of its functional characteristics and thereby ensure the preservation of the artistic and aesthetic expressiveness of products.
