Pros Of Fiber Mesh Concrete Like everything, fiber mesh has pros and cons about using it. You have to make sure it's suitable for your needs before you endeavor to use it for your project. Here are some of the advantages of choosing fiber mesh concrete. Holds
Often used in colder temperatures so the concrete crew has less waiting time between placing and finishing the concrete. Retarders slow the hydration, or hardening, of the wet concrete. Often used in hotter temperatures so the concrete doesn't set too quickly, allowing the concrete finishing crew to get the proper finishing work completed.
