Abstract
Concrete is a fundamental unit of the construction which is used in formation of building, marine construction and so on. The demand of those materials that can provide the high strength to the construction. Different types of fibers are added in particular amount in the concrete by which the mechanical properties, durability and serviceability of the structure are improved. The most important properties of Fiber Reinforcement Concrete is the resistance to cracking and crack propagation. Fibrous materials are contained by fiber reinforced concrete (FRC) that increase the structural integrity. Various types of fibers i.e., steel, glass fibers, natural fibers and synthetic fiber are used which provide varying properties to the concrete. Still, steel is used for the construction as constituent of concrete but it is very heavy material that increase the weight of concrete. Another drawback, it gets corrode easily within a short period of time. In the recent time, Civil engineering has found solution to overcome this problem by the use of basalt fiber that replace the steel, glass fiber and carbon fiber because of their properties. This paper study about Basalt fiber with its properties that make it a suitable material for the concrete. Basalt fiber has many application, discussed in this paper. Keywords: Concrete, Basalt Fiber, Fiber Reinforcement Concrete, Mechanical Properties
Introduction
TThe world’s most common used material in man-made constriction is concrete. It is assumed that steel is most common strengthening material for Reinforced Concrete (RC). This reinforcing material has many advantages like high tension strength, high modulus of elasticity. The material properties of steel is very stable because of their production process which is also very stable. With the advantages, the steel reinforcement has some disadvantages such as corrode as the time pass, low fire resistance, and the high cost which is increasing over last years.
The civil and structural engineers face a challenge as to provide a sustainable, financially feasible and environmental friendly to a society. Fiber reinforcement polymers (FRP) also have some drawbacks by which they are prevented from the use as a structural applications. Different types of FRP’s are used like FRPs composed of carbon called CFRP which have high elastic modulus and good tensile strength. While it is less desirable in case of fire testing and it is prohibited because of the high cost in the use. Another FRP is fiberglass, called GFRP that have good mechanical characteristics but have same issue ‘cost’.
Melted basalt rock fibers is a new development of FRP which create an excitement in the construction industry. Basalt is naturally occurring material and it is most abundant on earth. In 1920s, the production methods of FRP that composed basalt were found in the United State but large scale of production was not achieved until 1980s. The conventional concrete is not able to bring the steel at its tensile strength completely in use. This problem can be reduced by the use of BFRP and GFRP as these are more flexible than steel (Saad, Patel and Pethani, 2014).
