Relationship Between Technology and Building Waste

With the accelerated pace of Chinese modernization, a lot of construction wastes are produced, Disorderly dumping phenomenon can be found everywhere ,it is understood that the garbage dumping will not only take up a lot of land, but also serious pollute the environment, the accumulation of a large number of construction waste will destroy the soil structure, causing the surface settlement. In addition, the building construction waste glue, paint, paint or difficult biodegradable polymers containing harmful heavy metals in these wastes were buried in the ground, will cause groundwater contamination, direct harm to surrounding residents life.
With the continuous advancement of science and technology, the value of construction waste(such as the waste produced by hammer crusher, sand making machine) was excavated, according to experts, the reason why it is called the construction waste is that  these wastes are not effectively subdivided processing. Construction waste are actually change the physical properties of the building materials, the event that the classification and use of construction waste will likely become a gold mine in the eyes of the vision of building materials. Is true that there are some companies and even individuals began to turn its attention to this "gold mine".
Currently, construction waste resourceful utilization has already gotten the attention of the national people , during the two sessions, the members have proposed the Construction Debris legislation, strengthen the management of China's urban construction waste. According to Mr. Zhengzhou Dingsheng Engineering Technology Co., Ltd. engineer: "construction waste after the initial cleaning, sorting out recyclable steel and wood, then masonry, cement concrete blocks broken into aggregate after the height of construction waste disposal equipment R & D, After screening, to remove impurities, the formation of a certain size requirements of building materials. "

It is reported that the applied scale of recycled aggregates  is wide,they can be used as wall plastering materials, planting soil Backfill materials, brick-making industry, recycled concrete aggregate and recycled.

the recycled aggregate brick can be idvided into the   following kinds: the ground material eco-permeable bricks, pouring permeable brick, the permeable Road tooth brick three ecological permeable bricks are widely used in square, sidewalk, slow lane, open square, garden , slope protection, protecting group, highways and overpasses.
Meanwhile, planting soil regeneration is carried out   through  the construction waste sorting, and then crushed into powder, sludge as a raw material, add other kinds of wastes, including sewage treatment plant sludge, wineries and food plant residues, peat soil trace elements, according to the proportion of a certain quality, stirred by mixing together, in addition to the natural characteristics of the soil, with high fertilizer efficiency, breathable and water retention these characteristics.
