You do not want to put electric heating cables directly on top of a concrete slab!
Because the concrete slab will pull all the heat into it instead of allowing the heat to radiate up through the flooring surface.
You want to cover the concrete slab with thinset and then lay down ThermalSheet Insulating Underlayment before installing the heating cables.
ThermalSheet is a synthetic cork underlayment that is recommended when installing an electric floor heating system over a concrete slab to prevent heat loss.
This thermal image of a heated floor shows the temperature difference in a section of the floor that does not have any underlayment (upper left in blue) compared to the rest of the floor surface containing ThermalSheet underlayment. The result is dramatic. The area with ThermalSheet underlayment (insulation) heats the floor as intended.
