Cellulose fibers are fibers made with ethers or esters of cellulose. Produced from plant based materials, such as bark, wood or leaves they contain cellulose, hemicellulose, and lignen. With different content percentages the properties of the fibers change.
Adding processed cellulose fibers into concrete mixtures has positive effects on the impact and flexural strength, as well crack resistance. Using cellulose fibers also can reduce corrosion in comparison to steel reinforced concrete.
