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.
