Composite materials based on wood have currently been used in building structures, the quality of which is verified as early as when they are built into the building.
Results which were obviously significantly influenced by defects of materials were excluded from the evaluation.
Results of laboratory testing of materials sampled in this way give specific and measurable information.

Therefore, their structure is normally refined by rare earth materials, such as Titanium (Ti), Titanium-Boron (Ti-B) or zirconium (Zr).
The effect of adding some rare earth materials on the mechanical strength, wear resistance, impact strength, machinability, and fatigue life was thoroughly investigated in [9-15].

Introduction Concrete creep is a very complex problem for concrete structures especially pre-stressed concrete structures, it is not only related to the material properties, but also closely related to the applying load, tensioning time, the location of concrete, environment temperature, humidity, as well as many other factors [1, 2], and the exact value can’t be determined based on the current calculation of the theoretical and experimental means [3, 4].
