Concrete screws are probably the easiest concrete fasteners to use. They are likely the fastest as well. All they require is a hole to be drilled, the hole cleaned with a blast of air, and then the screw driven in to fasten the piece to the base material. The screws do not create pressure against the concrete or wedge in place, so they can be placed near edges. They cut their own threads into the base material and can easily be removed. Concrete screws are recommended for use with metal or ACQ treated wood to masonry applications.
