The post-tensioned industrial floors in reinforced concrete combine the advantages of the post-tensioning technique and the high structural performance of fiber-reinforced concrete.
Fiber-reinforced concrete (FRC) is a composite material based on a specific mix design of concrete to which metallic or synthetic fibers are added (depending on the case). The different components of the fiber-reinforced concrete (cement, water, aggregates, fibers, additives, additions, expansive agents, SRA) are mixed and proportioned in an appropriate way for the purpose, in order to create a flooring in accordance with the design requirements, both in the fresh state and hardened state.
The use of fibers in concrete is effective for
reduce shrinkage cracking
replace, in whole or in part, the reinforcement (welded mesh).
The fiber-reinforced post-tensioned flooring represents a more durable and technologically advanced solution as the mixed fibers in the concrete create a truly distributed reinforcement in addition to the active reinforcement of post-tension.
