The present disclosure provides a novel technique for creating bevels along the edges of flooring planks having a hard and rigid core layer, preferably comprising a magnesium-based cement or other type of curable binder material. The disclosed embodiments use the inherent time it takes for a cement binder in the core layer to harden and cure to concurrently shape bevels along one or more edges of the rigid core layer for one or more flooring planks.

A powder pressing device, such as a metal powder or ceramic powder pressing device includes at least one die and at least one punch. In a pressing position, the punch is arranged to be immersible from a first side of the die into a cavity filled with powder. The powder pressing device further includes at least one powder sealing device, which can have at least two parts. The powder sealing device can be arranged in sections, which can be arranged completely around the cavity.

Provided is a CFRP active-passive-confined compression-cast RC column incorporating cathodic protection, which includes a CFRP pipe; multiple longitudinal reinforcements inside the CFRP pipe; a stirrup inside the CFRP pipe connected to the longitudinal reinforcements; compression-cast concrete arranged in the CFRP pipe, the multiple longitudinal reinforcements and the stirrup are embedded in the compression-cast concrete; a power supply having a positive electrode connected to the CFRP pipe and a negative electrode connected to the multiple longitudinal reinforcements. The CFRP pipe with a present thickness forms an active confinement on the compression-cast concrete, and the power supply applies a current to the CFRP pipe as an anode to enable the multiple longitudinal reinforcements to obtain electrons, thus stably protecting the multiple longitudinal reinforcements as a cathode.

The present invention relates to a brick and a manufacturing method therefor, and provides a brick which has at least improved strength by comprising: as a brick material, soil (e.g., red clay, clay, kaolin, and/or dredged soil), sludge or the like used as a base material; and a solidifying agent for solidifying the base material, and a manufacturing method therefor. According to the present invention, particles of the base material constituting the brick are firmly gathered together, resulting in at least improved strength.
