Alternative Reinforcement Materials for Lightly Loaded Concrete Structures

Traditionally, high yield steel has been the common method of providing reinforcement in concrete, primarily due to its high tensile strength. However, steel is susceptible to corrosion, particularly in aggressive environments, leading to potential durability concerns and high costs in repair and maintenance.

Necessary rock studies of the gabbro and andesite basalt groups for the suitability as the raw material base for the production of continuous basalt fiber (CBF). A unique technique including laboratory melting and pilot-industrial melting at the high-tech equipment.

A promising solution to the problem is the use of fibre reinforced polymers (FRP) as a replacement for reinforcing steel. The use of FRP as reinforcement offers the following advantageous properties: it is lightweight and has high tensile strength, corrosion resistance and flexibility.

It is intended in this paper to study the effects of innovative fibre composite materials for reinforcing concrete. This study looks at the use of both basalt FRP rods and carbon FRP grid (C-Grid) as potential alternative reinforcement materials to address the problem of corrosion.

The investigation includes an experimental program to evaluate the structural performance of concrete panels reinforced with new forms of reinforcing material and will compare the results against more traditional reinforcement techniques in terms of the panels’ ultimate and service behaviour.
