EXPERIMENTAL INVESTIGATION OF BASALT FIBRE IN CONCRETE

Abstract

From the past few decades, the concrete industry and construction field is been observed a growing interest in the advantages that fibre reinforcement must be used in construction industry. Since the different types of fibres available in market, basalt fibre is considered as a promising new material to be used. Basalt fibre is extremely good in strength characteristics and thermal resistance too, high resistance to an alkaline environment, and is cheap product, making it an excellent material to be reinforced in concrete. In view of the consiquence of basalt fibres for concrete, and because of different lengths, dimensions and proportions of basalt fibres have an cause on the mechanical characteristics of concrete, it is suggested to review the effect of using different dimensions of basalt fibre and content on the mechanical properties of concrete. The mechanical properties of concrete examined are high compressive strength, high tensile strength, high flexural strength, permeability, workability, and the unit weight. This paper has been reviewed for the first time and the current literature related to the effect of using basalt fibres in different proportions on the mechanical properties of concrete, provided future researchers with the all their data and facts needed to compare their work, and identified the best basalt fibre dimensions and content combination that describes an improvement in the mechanical properties of concrete. From reviewing the literatures of various authors, it was found that most authors agreed that the mechanical properties of concrete was improved significantly when basalt fibre of  length between 12mm and 24mm, and content between 0.1% - 0.5% by total volume was used in concrete. In this context, the length and content of basalt fibres in concrete becomes an important factor for the mechanical properties of concrete.
