You still need rebar, unless you are filling a drop in an existing slab that already has steel in it.
You still need to use both, fiber mesh only helps with the small surface cracks.
Rebar is used to strengthen concrete because of its strength and flexibility. In order for these rods to work, there must be ample space between the rebar and the edge of the concrete piece.
The difference between the two is in the application. A development length is the amount of rebar length that is needed to be embedded or projected into concrete to create a desired bond strength between the two materials. The lap splice length is the length two rebar pieces must overlap and be tied together to create a bond as if there was no break and the run is "continuous". So simply put, development is rebar to concrete, splice is rebar to rebar. The lengths of both splice and development do vary. They are dependent upon different factors. These include but are not limited to concrete strength, rebar size, rebar coating and concrete cover or clearance. So when you see a chart on one project, it can differ from another for these reasons.

Rebar is used as a tensioning device in reinforced concrete and reinforced masonry structures holding the concrete in compression.
I have seen this done where a full mat was replaced in lieu of fibermesh. It is dependent on the intended use of the area where the slab is and ultimately if it is acceptable by the engineer of record for the project.

The amount of rebar in a cubic meter of concrete can vary depending on the design specifications of the concrete structure. Typically, rebar makes up around 1-2% of the total volume of concrete, so in a cubic meter of concrete, there may be around 20-40 kilograms of rebar.
To lay rebar for concrete effectively, follow these steps: Determine the required rebar size and spacing based on the project specifications. Place the rebar in the correct position within the formwork, ensuring it is properly supported and secured. Use tie wire to connect and secure the rebar at intersections and corners. Use chairs or supports to lift the rebar off the ground to the desired height. Double-check the placement and alignment of the rebar before pouring the concrete. By following these steps, you can effectively lay rebar for concrete to ensure a strong and durable structure.

Concrete & rebar
To ensure maximum strength and durability when installing mini rebar in a concrete structure, it is important to follow these best practices: Properly clean and prepare the area where the mini rebar will be installed. Use the correct size and spacing of mini rebar according to the design specifications. Securely tie and position the mini rebar in place to prevent shifting during the concrete pouring process. Ensure that the mini rebar is fully embedded in the concrete to provide maximum reinforcement. Use a high-quality concrete mix and proper curing techniques to enhance the bond between the mini rebar and the concrete. Regularly inspect and maintain the mini rebar to prevent corrosion and ensure long-term durability of the structure.
Rebar locators are used to find exactly where the reinforcing steel is located under concrete in existing materials. They are most often used for renovation or remodeling projects.
Epoxy is not required in rebar connections as concrete and wire are used to hold it in place. Rebar is a reinforcement place inside masonry structures to provide increased strength.
Concrete it self may not but most concrete structures .Has rebar in them and that can .
One example of securely attaching concrete to a structure is by using steel reinforcement bars, also known as rebar. The rebar is placed within the concrete formwork before pouring the concrete. As the concrete sets, it bonds with the rebar, creating a strong and secure connection between the concrete and the structure. This method is commonly used in construction to enhance the structural integrity of buildings and other infrastructure.
Items used to reinforce concrete are wire mesh, rebar, and steel cables.
