Fibre concrete havinga nanodisperse silica additive Фибробетон с добавкой нанодисперсного кремнезема
The objective of the project described in this article was to design the fiber concrete having an optimized structure and high strength characteristics. In the course of the project development, the fibre concrete was modified by the nanodisperse silica additive. As a result, the authors designed several modified fibre concrete compositions having optimal physical and mechanical properties. Electronic microscope Quanta 200 3D was used to study the microstructure of samples. Diffractometer ARL X’TRA was used to perform the X-ray analysis of samples. Selection of the optimal composition of the concrete was performed using the orthogonal experimental design technique. The nanodisperse silica additive was synthesized using method of chemical polycondensation followed by subsequent stabilization of acetate. This super-plasticizer improves the density and strength properties of the composite. Experimental and statistical models were generated as regression equations to determine the optimal composition of the fibre concrete.
