Application of Fiber Reinforcement Concrete Technique in Civil Constructions

Abstract

Deterioration of concrete structures due to steel corrosion is a matter of considerable concern since the repairing of these structures proved to be a costly process. Repair and rehabilitation of the civil structures needs an enduring repair material. The ideal durable repair material should have low shrinkage, good thermal expansion, substantial
modulus of elasticity, high tensile strength, improved fatigue and impact resistance. Reinforcing the concrete structures with fibers such as polyester is one of the possible ways to provide all the criteria of the durable repair material. This type of reinforcement is called Fiber Reinforcement of Concrete Structures. There is an increasing worldwide interest in utilizing fiber. reinforced concrete structures for civil infrastructure applications To study the commercial viability of FRC Techniques in civil construction, three slabs were constructed
by using polyester fiber along with cement matrix in Amara Development Association Training center ,Bahir Dar ,Ethiopia.The perfomace of the constructed slab was evaluated by various testing methods. The results of the experiment have strong implication to
apply this technology in civil construction works.
