Rehabilitation of deteriorated civil engineering infrastructures is mainly due to corrosion, destructive environmental situations, ageing, poor initial design or construction errors, poor maintenance and unintended situation like earthquake and has been a major issue in the last decade.

Aim: To investigate the behaviour of Basalt Fibre Reinforced Polymer (BFRP) bars bonded in to Irish Sitka Spruce (Picea sitchensis) using an Epoxy Resin. Step One: Analytical investigation. Step Two: Pull-out Tests to investigate geometric variables.

The data presented in the work imply that strength loss increases with the rise of phosphorus oxide concentration, which may follow the structure imperfection increase caused by the activation of liquation processes in the amorphous matrix.

The objectives of future researches on basalt fibres can be focused in the determination of feasibility and practicality in the exploitation of basalt fibre in reinforced polymer composites as beneficial material alternative for applications in which at the moment only glass, carbon and aramid fibres have a real market.

The presented data indicate that basalt has potential for replacing E-glass in several composites, especially when resistance to extreme conditions is required. However extra research may be needed e.g. on the adhesion with different resins.

Composites are emerging as realistic alternatives to the metal alloys in many applications like automobiles, marine, aerospace applications, sports goods, etc. Fiber composites offer many advantages such as low specific gravity, tensile strength and modulus, compressive strength and modulus, better fatigue strength, etc.

In this paper, to study the behaviour of RC beam structures strengthened by using basalt chopped strands fiber concrete.For this research work, Total 8 nos. of beams can be taken.

In this study, the strain rate effect on the bending properties of fiber reinforced composites for three types of polymer composites namely phenolic resin reinforced by woven basalt fibers, woven carbon fibers, and woven basalt/ woven carbon fibers at a total volume fraction of approximately 35% has been determined.

In order to evaluate the changes in the flexural properties of three types polymer-matrix composites (phenolic resin reinforced with woven basalt and carbon fibers at a total volume fraction of approximately 35%) affected by transient thermal conditions, mechanical tests were performed to specimens, which have previously been subjected to a certain number of thermal shock cycles.

The applicability of basalt fibers as reinforcing materials has been examined in a polypropylene (PP) matrix. The brittle basalt fibers have been mixed with the PP fibers by carding combined with needle punching and the composite sheets have been produced by pressing.
