THE USE OF GEOMETRIC MODELING IN THE DESIGN OF MIXERS AND DEVICES FOR ADDITIONAL SEALING OF FIBER-CONCRETE PRODUCTS

Geometric modeling as a kind of mathematical modeling plays an important role in solving modern problems of science and technology. Construction of geometrical models that adequately reflect the properties of the designed materials and products, processes, and etc. significantly reduces the cost of the experimental studies, accelerates the design and implementation of various innovations in production. Building an effective geometric model of the product or process affects the level of technical solutions in the design of new competitive construction elements. Recent widespread use of the fiber-reinforced concrete can significantly enhance building constructions by reducing the cracking of the material during the operation and increasing its resistance to shock loads, as well as stretching and bending. However, experience shows that in practice today it is difficult to obtain uniform fiber reinforced concrete. The reason for this is the use of traditional technological methods for making such a complex material such as fiber concrete. The use of traditional mixing equipment for concrete and mortar does not provide a highly uniform fiber reinforced material. Purpose. Development of technological schemes of preparation of fiber reinforced concrete (using geometric modeling for formation of various pieces of equipment) on the basis of the developed model of mixing fiber-containing building materials. Conclusion. Tests have shown that the application of the developed equipment can significantly improve quality of preparation and packing fiber concrete mass. Using a mixer designed with a flexible body with gutters of variable profile ensures high uniformity of dispersion-reinforced blends with the spread of the strength of up to 3 percent. Due to the high quality of mixing time of mixing is reduced, and this, in turn, reduces the cost of hardware maintenance and power. Our proposed mobile technological methods of production can significantly extend the scope of fiber reinforced fine-grained concrete (and provide high quality composite).
