Systems and methods for forming a channel in an uncured concrete slab are described. The system includes a first blade, a second blade, and a third blade. The first and second blades are oriented vertically relative to the concrete slab and spaced a predetermined distance apart. The third blade is positioned between the first blade and the second blade to form a concrete-receiving interior. The system also includes a conveyer having fin(s) extending therefrom to move material through a chute. The first, second, and third blades are configured to cut the channel in the concrete slab and direct excess concrete into the chute where the conveyer moves the excess concrete out of and away from the channel.

A molded article having a small difference in thermal conductivities between a central section and a section located at an outer peripheral surface side; and a method for producing the same; wherein, a plate-shaped molded article includes an aluminum-silicon carbide composited section in which a metal including aluminum was impregnated into a silicon carbide porous body, wherein a difference in the densities, by Archimedes' principle, of a central section of the aluminum-silicon carbide composited section and of at least a portion of an outer side section located further toward the outside peripheral surface side than the central section is 3% or less.
