A ceramic matrix composite (CMC) component is provided that includes: a CMC body in which an environmental protection layer is completely embedded within a CMC material of the CMC body, the environmental protection layer comprising a ceramic that has a higher impact and/or environmental resistance than the CMC material. Methods for manufacturing the CMC component are also provided.

Described is a method for restoring a cementitious system, the method having the following steps: a) securing a filling body provided with holes at a distance from the cementitious system to be restored, b) applying mortar to the cementitious system to be restored and to the filling body provided with openings, and c) introducing a cement containing an alkali storage system into the filling body provided with openings so that the cement containing an alkali storage system is in contact with the mortar. A corresponding cementitious system is also described.

A method of manufacturing a honeycomb structured body, includes providing an application jig. A sealing material paste is put on a peripheral surface of a pillar-shaped ceramic block. The application jig is set in such a manner that a first principal surface of the application jig faces upward and a second principal surface of the application jig faces downward. The ceramic block is placed inside a second opening section of the application jig. The ceramic block is passed through an opening section of the application jig so that a face defining the second opening section spreads an entire peripheral surface of the ceramic block with the sealing material paste to manufacture a honeycomb structured body with a peripheral sealing material layer formed on the peripheral surface of the ceramic block.

Disclosed herein are corrosion-resistant composites. In particular, the composites can include a piezoelectric material embedded within a binding medium that can impede or inhibit the corrosive effects caused by salts and acids. Also disclosed herein are methods of making the composites and methods of protecting a concrete or concrete-related substrate from corrosion.

A method of manufacturing a metal-coated member includes: providing a composite ceramic member including a ceramic part, and a connection part connected to the ceramic part; disposing a precious metal layer on a surface region that includes at least a portion of a surface of the ceramic part and a portion of a surface of the connection part, the precious metal layer including a precious metal; and removing at least a portion of the precious metal layer that is on the surface of the ceramic part and delineated by the boundary between the ceramic part and the connection part. The connection part has stronger adhesion to the precious metal than the ceramic part.

A method of applying a surface coating to a concrete surface with a joint wherein the method comprises the steps of: applying a primer layer to the concrete surface including the joint; applying a first laminate layer to the concrete surface excluding the joint and a region of the concrete surface surrounding the joint; applying a second laminate layer over the first laminate layer; applying a first flexible laminate layer over the region of the concrete surface surrounding the joint; applying a geotextile fabric layer over the joint and the region of the concrete surface surrounding the joint; and applying a second flexible laminate layer over the geotextile layer and a portion of the second laminate layer.

A method of manufacturing a metal-coated member includes: providing a composite ceramic member including a ceramic part, and a connection part connected to the ceramic part; disposing a precious metal layer on a surface region that includes at least a portion of a surface of the ceramic part and a portion of a surface of the connection part, the precious metal layer including a precious metal; and removing at least a portion of the precious metal layer that is on the surface of the ceramic part and delineated by the boundary between the ceramic part and the connection part. The connection part has stronger adhesion to the precious metal than the ceramic part.
