Revisiting the structure optimization of high strength fiber concrete through the use of nanodisperse modifier

One of the most relevant problems of the present, especially in the industry of construction materials in Russia is energy saving. Energy costs per unit of output in Russia are 2 to 3 times higher than in the developed countries of the world. Now the volumes of technogenic deposits, as well as the current wastes, are significantly greater than the needs of enterprises of construction materials industry in raw materials. Therefore the problem of selling technogenic raw materials is particularly acute. At the same time, fiber reinforced concrete is widely used now. It is a relatively new material, which allows to obtain a high economic effect due to longer service life, higher durability and wear resistance. During the pilot studies, composition and properties of high-strength fine-grained concrete, based on composite binders and technogenic sands for the production of a wide range of products are developed.
