The use of Macro Beton fiber reinforcement in the construction of rail systems eliminates the labor of reinforcement and offers the easiest form of application; provides a minimum 30% time advantage. The most important safety factor in rail systems and especially in under-rail concrete is electrical conductivity. Maximum safety is provided with non-conductive Macro Beton synthetic fibers. It shows high performance after cracking by keeping the concrete together with the help of 3-dimensional strength and durability.
