Experimental Study on the Performance and Classfication Systems of Recycled Concrete Coarse Aggregate
With the fast development of construction and transportation, there is a great deal of waste concrete produced every year in the world. The processing of the massive amount of waste concrete will cost a lot of money. Moreover, it will bring about a series of problems including natural resources, energy, environmental protection and sustainable development, [...]
Study on the Changes of Pore Structure and Functional Group During Blended Coal Combustion
At present, most of power plants are actively or passively in use of the blended coals. In order to use the blended coals reasonably and effectively, economize the coal resource, increase the efficiency of boiler and maintain safely, effectively and economically operation of the power plant, it is necessary to systematically study on the changes [...]
Study on Microstructure and Properties of Road Cement Concrete
There is no exception to Road cement, the microstructure of material decides its macroscopic performance, and the internal structure of different dimension directly influences the macroscopic durability. Therefore, a deep research in the relevance of road concrete’s microstructure and macroscopic performance has the vital significance to essentially recognize the workability and rule of the cement [...]
Experimental Study on Durability of Dry-Mixing Self-Compacting Concrete
Not only for its common properties of self-compacting, the most important feature of dry-mixing self-compacting concrete (DSCC) is the commercialized production of its main materials (short for base material). Only we need do is adding some water and coarse aggregate into the base material, then stirring uniformly. The mixing proportion needn’t be designed in the [...]

Effect of Concrete Pore Structure on Chloride Diffusivity
In recent years the durability of concrete structures has attracted extraordinary civil engineering because of its huge economic costs.Besides the cost of rebuilding and maintenance, it is also related to the protection of environment and the sustainable development of society.One of the most important factors for the durability of concrete structures is the serious corrosion [...]
Synthesis and Capacitive Performance of Ordered Porous Carbon Via a Template Method
In recent years, supercapacitor as a new type of energy storage device has received much more attention from governments and research workers. Porous carbon materials are usually used as the electrodes of electric double layer capacitors (EDLCs). Even the micropores are important for aqueous electrolyte system, however, when the micropore size is too small, the [...]
Research on the Experiments about the Pavement Performance of Cement-Fly Ash Stabilized Steel Slag
As the iron and steel production technologies have been greatly improved, but also led to a large number of abandoned slag heap, not only pollute the environment, they take up a lot of land. Of this, many countries have begun to focus on seeking to exploit a large amount of slag simple and feasible use [...]
Study on the Influence of Strength and Durability of Concrete Owing to Different Qualities of Silica-fume
In the past few centuries, More and more reinforced concrete structure destories due to insufficient durability caused by progressive worsening environment,which causes great loss of national economy. The durability and reliability of reinforced concrete structure has become a worldwide problems and causes great attentions. There are also many experts and researchers at home and abroad [...]
Study on the Temperture Charactteritics of the Large Pores of Cement Concrete Pavement
With the improvement of living standards of the urban residents, the environment that people living around have raised higher requirement. At present,urban heat island effect become a factor which influence Living standard. In this context, we propose a large pore cement concrete pavement, by changing the porosity, pore structure, pore diameter and other factors, to [...]
