The invention relates to a process for producing a component (1) from a curable material, a new layer (2) of the material being printed in periodically recurring steps in a 3D printing process onto a layer (3) located thereunder so as to have lower reinforcing elements (4) which protrude above the top of this new layer (2), and also relates to a component produced by a corresponding process. Known processes and components do not allow reinforcement over a large surface area.

The object of designing a process in such a way that the reinforcement thereof withstands high loads is achieved by providing that, after each layer (3) has been printed, upper reinforcing elements (5) are connected to the lower reinforcing elements (4) so as to extend said lower reinforcing elements and so as to form the lower reinforcing elements of the subsequent layer. A corresponding component is the subject of claim 11.

The invention relates to processes for making improved ultra-high performance concrete with plasma-treated inclusions and articles made from the same. The invention includes a process for producing silicon carbide and multiwalled carbon nanotubes by heating agricultural waste husks in an inert atmosphere to a temperature higher than 1300 degrees C. to obtain a mixture containing silicon carbide and MWCNTs, and treating the mixture to extract the silicon carbide and MWCNTs for use as microinclusions in ultra high performance concrete.

A honeycomb structure has a plurality of cells formed by a plurality of partition walls. The partition walls are formed of a porous material composed predominantly of cordierite. Each partition wall includes surface layer portions having a porosity of 50% or more and an inside portion having a porosity of 50% or more, the surface layer portions being portions ranging respectively from opposite surfaces to a depth corresponding to 25% of the thickness of the partition wall, and the inside portion being the other portion. The surface layer portions and the inside portion both include pores having axial pore widths of less than 30 μm and pores having axial pore widths of 30 μm or more. A mean axial pore width in the surface layer portions is smaller than a mean axial pore width in the inside portion.
