X-ray diffraction analysis.Concrete exposed to high temperature considerably changes its properties down to total destruction. The paper describes renovation of concrete floor damaged by a fire of a factory building. Individual steps of determination of damage of concrete floor structures caused by high...
concrete floorreinforcementetthryngitX-ray phase analysisThe reasons of crack formation in vacuum concrete floors with reinforcing mineral wear-resistant coating were investigated. The main reasons of crack formation are connected with low concrete strength due to the lack of water for cement hydration,...

X-ray methods use radioactive material. The radiation exposes the film, much like it does in the medical industry. As a result, the general public, employees, or other non-essential personnel must not be in the vicinity of the X-ray radiation. This is ...
(GPR) to accurately pinpoint the location of each hazard and map it in detail, so there is never a question of where you can cut and where you can’t. Unlike concrete x-ray services, GPR concrete imaging does not require you to close off sections of your site to avoid radiation. In...
Add character to a basic concrete floor or slab with the added benefit of crack prevention. WIRE SAWING Hi-tension diamond-coated wire will cut any shape or depth. WALL SAWING Precisely-cut openings for selective demolition without the threat of structural damage up to 72" deep. ...

The model was completed by introducting a rigid support that simulated a concrete floor. With this model the effect of varying floor roughness and claw-floor friction on contact pressures and von Mises stresses in the claw horn was evaluated. Under loads up to 6 kN, contact pressures up to ...
