Numerical modelling of deflagration explosion of gas in industrial build-ings. Location of safety constructions.
Budnik E.V., Pepelyaev A.A.
The failures caused by explosions of gas, occur regularly. The main reason for these failures is the human factor, to exclude which and to foresee emergence of failure it is almost impossible. At failures of gas in the closed rooms of buildings there is a so-called deflagration explosion. Such an explosion can damage or destroy a building and cause serious injures to people. In the work is simulated explosion in the industrial building with regard to different gas concentration in order to understand the dependence of the maximum excess pressure from this fac-tor. Discusses optimal location of safety constructions. In the work for calculation of intensity of explosive loading and identification of influence of the gas concen-tration we used the domestic multi-purpose program FlowVision complex.

Shchetkova E., Sevastianov R.
The present work is devoted to the physical and chemical aspects of the conversion of chrysotile fibers in the formation of fiber-reinforced concrete based on Portland cement binders. This knowledge will allow to model composite structure at the micro level and to manage its effective physical and mechanical properties. Based on the criteria of efficiency particulate reinforcement fiber-reinforced concrete and the requirements for reinforcing fibers analyzed the structure and physicomechanical properties of chrysotile. The paper summarizes and analyzes the interaction between the chemistry of chrysotile fibers with the components of the concrete matrix. The mechanisms of interaction between the components and the impact on the final characteristics of the fibers of chrysotile fiber-reinforced concrete, especially for strength. The facts presented lead to the conclusion about the effectiveness of chrysotile asbestos as a reinforcing agent for reinforcing fiber-reinforced concrete. It is shown that chrysotile fibers have good mechanical and environmental properties subject to the rules of industrial safety.
