Asia-Pacific – The most Dominant Region in the Concrete Fiber Market
The concrete fibre market in Asia-Pacific is one of the fastest-growing markets and is projected to continue to dominate well into the future. Asia-Pacific is also the biggest market for concrete fibers, and accounted for a share of more than 44% of the total market share in terms of volume in 2014, which was mainly contributed by China.
India is the fastest-growing concrete fibre market in the region owing to a growing population, sustained building development, favorable investment policies, and government initiatives to promote industrial growth.
The U.S. and China are at the forefront of concrete fibers demand, while outside Asia-Pacific, Germany, France and the U.K. are the other key markets.
Presently China remains the key market in Asia-Pacific, closely followed by India, Japan, and South Korea, where demand is growing at a steady rate.
“The Concrete Fiber Market will be worth approximately 3 Billion USD by 2020.”
Why use Fibres in Concrete
There are many reasons why the fibre market will continue to grow for reinforced concrete. Concrete is brittle and lacks toughness and ductility; it also has limited flexural/split tensile strength. Concrete has low abrasion and wear resistance and does not adequately safe guard steel reinforcement from permeability. Concrete over time inherently produce micro cracks and its propagation has a limited impact resistance.
Both natural and man made fibers used as reinforcement can overcome the above problems associated with concrete. Natural fibers are available abundantly in nature and can be used to reinforce polymers to obtain light and strong materials.
Fibers such as Banana fiber, Kenaf, Hemp, Bamboo, Jute, Polyester, Polypropylene, and Glass are used in reinforcement of concrete. These fibres enhance the ductility and toughness of the cement matrix, and increase significantly its tensile, flexural, and impact strength.
Fibers also act as an internal support system retaining a more homogeneous concrete mix. Fibers discourage the natural segregation and settlement of concrete ingredients.
The internal support system provided by these fibers results in a more uniform bleeding, because the mix water is not displaced and rapidly forced to the surface by downward movement of concrete ingredients.
“Kenaf fibre helps increase the flexural and tensile strength of concrete. Some studies show that this can be as much as 3 to 5 times stronger.”
EA Kenaf Fibres
There have been numerous studies that look at the benefits of including Kenaf Fibres with concrete. Results have uniformly shown that the Kenaf fibre helps increase the flexural and tensile strength of the concrete.
Some studies show that this can be as much as 3 to 5 times stronger.
It is because of these facts along with the added benefit of a substantially lighter product, better insulation characteristics and the permanent sequestration of carbon; that we have many companies now using our kenaf fibres in various types of concrete.
Some of the advantages of natural kenaf fibre reinforced concrete (KFRC) included increasing toughness, enhancing cracking behaviour, enhanced durability and improving fatigue and impact resistance.
