A decorative concrete with a very uniform finish surface and a method of fabricating the same is disclosed. A concrete mixture is poured over a subgrade which defines an exposed surface. The exposed surface is finished with any of several techniques, and the surface is then worked with an abrasive material, and additional techniques are used to color and seal the concrete.

A robotised construction system is provided that includes a cartesian robot that can be automatically lifted as the construction is becoming higher, that is provided with a system of robotic supply of the materials and of the electric and electronic installations and that is provided with specific fabrication tools which work some by the contribution of layers of fluid construction materials. In a cement-based usage in which the cement is setting and having been deposited, by projection of these same materials and others by forming and placing construction elements in a determined position.

A repair process for an article such as an airfoil includes providing an article that has a substrate and a ceramic barrier coating disposed on the substrate, where the ceramic barrier coating has a damaged region, abrading the damaged region to provide dimple in the ceramic barrier coating, wherein a remaining region of the ceramic barrier coating adjacent the dimple remains intact, and depositing a patch of networked ceramic nanofibers in the dimple.

An apparatus for curing concrete includes a multiple layer polyolefin film and an absorbent layer. The polyolefin film layer can include pH modifying components and antiskid components. The absorbent layer can also include pH modifying components. The absorbent layer can include nonwoven fabric. The apparatus can be applied to curing concrete after hydration water is applied to the curing concrete. The apparatus can also be used to enclose poured concrete members during transport of the members so as to continue the curing process during transport. The film can also be used as a barrier layer between the ground and poured concrete.

A composite substrate includes a supporting substrate and a functional substrate that are directly joined together, the supporting substrate being a sintered sialon body.
