Introduction Diamond is the hardest material and is widely used as cutting, grinding and polishing tools, diamond tools are usually prepared in the form of composite structures, wherein diamond grits are bonded using either a plastic, ceramic, or metallic bonding matrix.
The Cr carbide may be formed by the reaction between Cr and C at elevated temperature, and the corresponding Gibbs free energy (unit: [J]) (T unit: [K]) could be described as follows [5,6]: (1) The brazing temperature should not be excessively high, because the cubic structure of the synthetic diamond can transform into laminar graphite or carbon when exposed to high temperatures (here as the temperature of 1323K).
In brazed processing, owing to the inherent flaws of diamond crystal structure, the crystal lattice vibration intensified at the high temperature.
The structures of the formed compounds were decided by the atomic ratio of C and Cr. the quantity of Cr atoms is insufficiency to form Cr3C2 [6].

Verified to the top surfaces of the membranes with 1 and 5% w/w of CaCl2 (Figures 1 and 2), independent of the exposure time at which they were subjected, showed a structure denser and the presence of a small amount of pores, or closed cells.
All end surfaces of the membranes 15 and 20% w/w of CaCl2 (Figure 4 and 5), irrespective of the time of exposure, show a very open and irregular morphological structure, with the presence of regions sponge and the predominance of macrovoids, which dramatically increases the porosity of the entire superficial layer of membranes analyzed.
Based on the results and discussion, it was verified that the addition of 1% and 5% w/w of CaCl2, promoted the formation of a denser structure and the presence of a small amount of pores, or closed cells.
While the addition of 15% and 20% w/w of CaCl2, showed a structure irregular and very open, in the presence of foamed regions and the predominance of macrovoids.

Results Pictures of the steels structure are shoved on Fig. 1.
Analysis of the structures revealed that steel 1 has ferrite-pearlite microstructure (87% ferrite, 13% pearlite), steels 2 and 3 have ferrite-bainite microstructure (30% ferrite, 70% bainite and 40% ferrite, 60% bainite corresponding) (Fig. 1).

The surfaces affected by mould may be an example of the apparent degradation by moisture on the building structure [5].
The method of chemical injection is more and more commonly used due to the development of new technologies in the field of structural chemistry.
However, there is a change of the emissivity of the structure surface.
This fact allows us to infer the reach of grouting if the injection medium affects the surface of the remediated structure.
