More precisely, it is suggested that, in parallel to the introduction of robotic fabrication methods, digital technologies may be key for the introduction several innovations like (i) rebar-free reinforcement using non-convex granular media; (ii) compression-optimized concrete structures, using ...
materials in a wide range of areas, straw mud wall, steel bar reinforced concrete, and tire cord, etc. all belong to the scope of composite materials. From analysis of the composition and the internal structure of composite materials we found that it includes three basic physical phases. One...
Once travelling waves are present in the disc, they interact with a ceramic sphere in the metallic foam leading to the gradual destruction of the cutting disc. The multitude of waves traveling with various radial and angular frequencies overlay or diverge in time, depending on their relative ...
At present there is a pressing need to find an environmentally friendly grouting material for the construction of tunnels. Silica nanoparticles hold great potential of replacing the organic molecule based grouting materials currently used for this purpose. Chemically, silica nanoparticles are similar to n...

Fly ash can react with portlandite in the presence of water to form cementitious compounds. As portlandite is the main hydration product of cement and is present as reactive calcium hydroxide, there is a distinct attraction in adding fly ash to concrete. There are two types of fly ash, as ...
In general, stone and/or brush are used as basic structural components in these buildings, while mud is generally used to fill in the space between, acting as a form of concrete and insulation. Synthetic materials: Plastic is an excellent example of a typical synthetic material. The term ...
