Experimental Descriptions 2.1 Materials and Samples In our experiment, there were two kinds of samples: concrete and paste.
A mechanical 300 KN material test system (MTS) was used to carry out stress-strain curve measurement under uniaxial loading.
Fig.2 Loading test setup 2.4 Analysis Methods The pH value in the pore solution of cementitious materials in higher than 12.5, creating a very basic environment.

First, the old materials used one hundred or more years ago are poorly known today, if at all.
An experimental campaign was carried out in order to find the elastic parameters and strengths for individual materials (clay unit and mortar).

A few to mention, ferrite-based magnetic materials: Fe-35Co/Fe3O4 composite prepared by solvothermal method.
The two mentioned types of magnetic and dielectric materials have been used as absorbing materials for electromagnetic waves.
Such three physical properties are needed by materials capable of absorbing the electromagnetic waves.

The coatings increase the creep strength and also the local thermal stress in the near-surface areas due to the differing thermal expansion of particular material layers.
Introduction The extreme operating conditions of modern aircraft engine turbines require the application of heat-resistant and high-temperature materials.
The material most frequently used as the top coat is the zirconium oxide stabilised with yttrium oxide - ZrO2+Y2O3 [4,5].
