Potassium hydroxide and sodium hydroxide in concrete existed, they were also reactive material.
Tobermorite of cement hydration and secondary reaction was also reactive materials that reacted with carbon dioxide.
Although these materials carbonization properties were not different, the more these materials if these materials existed more in concrete , the slower carbonizing progress were.

Besides, the effect of auxiliary phase materials and the operating temperature on the sensing characteristics of the device has also been investigated.
The XRD pattern shows the composition of the auxiliary phase materials are AR Ag2SO4 and BaSO4 and the SEM image reveals that the materials mixed well and the granular analysis shows that the median diameters of it was 13.972um, it is consistent with the SEM image.

Bronze based alloys have come to be used as bearing materials, and require low frictional properties.
Introduction Owing to their high thermal conductivity and machinability, copper (Cu) based alloys have come to be widely used as bearing materials.
On the other hand, the surface of the bearing materials is usually finished by means of machining such as turning and milling.
Materials 2.1.
Materials The material used for the present study was sintered bronze containing micro-sized sulfide phase consisting of Cu-Fe-S(S-bronze).

Secondly, all gathered data is processed and transformed into product ideas combining silhouettes, materials and colours[1].
The investigated terms and concepts include clothes, materials, color, person, season, etc.
The classes in meta-ontology include clothes, components, materials, style, season, place, person etc.

When the tensile stress surpasses the material the tensile strength, the outer wall can appear the crack (Fig. 1).Inside compressed stress oversized, surpasses the material the flexure stability, can appear the Wrinkling (Fig. 2).
On the other hand, the metal material surpasses the yield strength to enter the plastic state, the stress - strain course no longer is the linear relations, moreover and load process related, existence material non-linearity.

Provision of facility construction with the necessary materials and structures should be planned while minimizing the combined transport and storage costs with account of the rational scopes and reliability of supplies ensuring the rhythmic process of facility construction.
Reliability of material support of construction operations is the system’s capacity to assure complete and uninterrupted material support of construction works.
Thereat, rhythmical work must be ensured by creating the minimum amount of material reserves at the facility warehouse. 3.
