Serious deterioration may be caused by insufficient durability design with optimistic assumptions against materials deterioration and by lack of proper maintenance after construction of infrastructure.
The progress of deterioration differs widely by its location because of inhomogeneous characteristics of materials and diversity of environmental conditions.
The tissues of the test materials were examined in the axial direction.

The key problem of speeding-up construction the low carbon housing industry system In the real economic activity，the aspects of building, construction, heating, ventilation, air conditioning, lighting, electric appliances, building materials, thermal technology, energy, environment, and detection, etc. are involved in the housing industry system.
From the view of the housing industry chain, all links of the housing science design, the use of new technology & new material, the innovation way of the construction & organization, even decoration are included in the low carbon housing industry system, but also many parties of the suppliers of building materials, the real estate development enterprises, the decorate adornment enterprise are involved.
In the upstream of industry, new materials, new technology, and new handicraft have constantly emerged, and the technology of low carbon housing has made much progress.

EAP materials are classified in two major categories: ionic EAPs, activated by an electrically-induced transport of ions or molecules, and electronic EAP, activated by an external electric field and by Coulomb forces ([10],[11]).
Table 1 summarizes this classification, listing for both types of EAPs the most representative materials.
For each category of material the fundamental figures of merit for actuation are improving all the time.)

Therefore, it is necessary to find a new sewage-corrosion-resistant material in order to reduce the damage of acid corrosion caused by the the metabolite products of the microorganisms for sewage treatment system and provides better seivice for the production.
In each period, test the flexural strength values and compressive strength values after folding in the two acid corrosion solutions and the fresh water environment. 2) Experiment Materials Concrete raw materials.
In the experiment, the materials used to produce the normal concrete and SFRC are as follows: 42.5R ordinary portland cement for cement; Gravel with the size 5mm-10mm for coarse aggregate, qualified for the demand; River sand with the fineness modulus 2.5, qualified for demand; Distorted I-shaped fiber for steel fiber.

The Survey and Choice of Water Device in Beijng Market The market survey of water appliances, covering 3 classes (according to the size of the market positioning),9 building materials market in Beijing, according to sampling the form of research.
In the investigation we found that, there are many high-grand products in the building materials market, such as: ToTo, Kohler, Arrow, Grohe and others have varying degrees of different scale counter.
Standing two specifications in the city building materials and building materials supply market, middle and low brand are involved.
Building materials market concentration is low as 30 ~ 50 yuan products, these products factory also do OEM for mid-range brand, quality is ok.

In the assumption that belt material is deformed in linear elasticity and the flat belt drive is running in steady state, the dynamic equilibrium equations of radial and tangent directions are presented and simplified through the belt infinitesimal element processing and the equations associated with mechanical coefficients and dimensions are also derived.
Dynamic equibrium equations for belt drive in steady mode It is on the assumption that the flat belt drive is in steady motion, the belt material is linear-elastic, and the material heterogeneity in the belt are not considered for simplicity.

This article presents a description of the existing state of the Aghjots monastery and importance of the detailing geometrical survey, decay and material mapping.
This means that the evaluation of the structural behavior has to be approached through an assessment of the current condition of the structure and its history in term of material properties, construction techniques, structural details, crack pattern, damage map, and material decay [5].
