Therefore, the structural frame ensures the bearing function, whereas the infill wall serves to separate inner and outer space, filling up the boxes of the outer ...
Decorative plate made of Nano concrete with High-Energy Mixing (HEM) Two-layered pavers, pigmented top layer made of HEM nanoconcrete Nanoconcrete (also spelled nano concrete or nano-concrete) is a form of concrete that contains Portland cement particles that are no greater than 100 μm [1] and particles of silica no greater than 500 μm, which fill voids that would otherwise occur in normal ...
Stamped concrete is an architectural concrete that has a superior surface finish. After a concrete floor has been laid, floor hardeners (can be pigmented) are impregnated on the surface and a mold that may be textured to replicate a stone / brick or even wood is stamped on to give an attractive textured surface finish.
