The recycling of waste in civil engineering is important as long as it reduces costs and protects the environment. In several countries of the world, different wastes have been used to replace cement or aggregates, such as mineral admixtures, powders and fibers. The aim of this work is to study the influence of fibers from factories and lathing workshops on concrete slump, compressive strength and 3-point flexural strength. The tests have been carried out on concretes containing different types of fibers: stretched steel fibers, fine steel fibers, looped steel fibers and looped aluminium fibers, in proportions varying from 1% to 3% by weight of aggregate. The results show that the behaviour of the concrete in the fresh and hardened state is different depending on the fiber type and content. Fiber distribution analysis was carried out to support the discussion of the results using Gwyddion software. [ABSTRACT FROM AUTHOR] |
