Reinforcement makes the concrete stronger, in particular it gives the concrete tensile strength as opposed to just compression strength. It must be used for certain types of foundations / types of ground and also other forms of construction too
Concrete are used without reinforcement bars on concrete roads.
Concrete reinforcement mesh is not called BRC. BRC is the name of a company that supplies reinforcement and it may be that the buyer has specified that it is supplied by BRC.
Under reinforcement is safe because in this case steel fails before concrete.
A cover meter determines the distance from the outside face of the concrete to the depth of the reinforcement bar.
The concrete would be weaker, and more prone to cracking.
Microfiber is used as a reinforcement in concrete structures to improve their strength and durability. The small fibers are added to the concrete mix to help control cracking and increase the overall toughness of the structure. This reinforcement helps to enhance the performance of the concrete and make it more resistant to various stresses and strains.
Reinforcement
to support the concrete
Concrete wire mesh provides structural reinforcement, improves crack resistance, enhances load-bearing capacity, and helps in distributing stress evenly in construction projects.
Actually concrete is not very good in tension therefore we have to introduce reinforcement which takes care of the tensile stresses. If we don't provide reinforcement, concrete will start showing cracks wherever tensile stresses overcome the concrete tensile strength.

The reinforcement may be in the form of "mesh" or rods. The steel reinforcing rods are colloquially called rebar(reinforcement bars).
