HIGHLY EFFICIENT BASALT FIBER-REINFORCED COMPOSITE SYSTEMS

Abstract

In present paper are presented experimental-theoretical researches of fiber reinforcing such as more effective method for high physical-mechanical and exploitation properties cement composite acceptance. Comparative characteristics of technical properties for more prevailing reinforced fiber which are successful applied in building, including basalt fiber, are carry out. Theoretical validated and experimental affirmed basalt fiber advantage, involving in uncial properties such as high level physical-mechanical and chemical characteristics, durability and so on. Use of basalt fiber, introduction of which in minimal amount due to disintegration on monofilament with great specific surface lead to three-dimension micro reinforced cement matrix formation, which are effective counteracted to compressive and tensile stresses, taking place in concrete on external force interactions. Basalt fiber insertion in expansive cementitious systems lead to partial restriction composite self strains and due to high adhesion with modified cement matrix tensile strength are increased. Applying of basalt fiber jointly with self-stressing cement allow to avoid not just only cement composite strength properties, but also increasing impermeability.
