Fibers for concrete reinforcement can be divided into several types. In general, most of the fibers used in construction are made of steel or modern polymers. Polymer fibers are most often made of polypropylene, polyethylene, polyester, acrylic or aramid. Steel for concrete reinforcement, on the other hand, can be made of alloys of various strengths and has different properties. Other types of fibers used in construction for reinforcement dispersed in concrete are natural fibers such as glass fibers or carbon fibers, which are characterized by a high modulus of elasticity and very high durability.
Concrete reinforced with fiberglass is an excellent solution
By classifying fibers due to their size, we can divide them into two categories, macro and micro fibers. Macro fibers are sometimes referred to as structural fibers and are designed to transfer the load acting on the floor, and are therefore used to replace the traditional reinforcement in concrete. Typical fiber lengths of fibers are approximately 3 to 5 cm. Micro fibers, on the other hand, are commonly used to minimize the contraction of fresh concrete in the industrial floor. Micro fibers are classified according to length, although sometimes also in diameter or proportion. Before adding to the mixture, they resemble feathers, and when mixed in concrete, they evenly decompose, creating an even structure resembling a grid of short threads. It is important to remember that only macro fibers can be used as a substitute for wire fabrics and reinforcing steel.
How the GRC suppliers in the UK are helping with the modernization of municipal infrastructure?
Fibers improve most concrete properties including tensile strength, compression, modulus of elasticity, resistance to cracking, resistance to fatigue, impact and abrasion resistance, shrinkage, improve thermal properties and fire resistance. Floors that are reinforced with fibers have an increased load capacity even after the initial fracture and continue to carry loads.
For this reason, GRC suppliers UK are so willingly used. In United Kingdom recently such a solution is being used more and more because it is thanks to him that you can, among others, modernize the old sewage system. However, we must also not forget that such concrete is also used in other modernizations of municipal infrastructure.
