< P > < FONT face = Verdana > < FONT face = Verdana > Recently, the reporter learned from Hohhot, Inner Mongolia that renewable green concrete was born in Inner Mongolia, jointly developed by Inner Mongolia Dexin Real Estate Co., Ltd. and Tsinghua University. This initiative has solved another new chapter in the current green building. < P > < FONT face = Verdana > Today, waste concrete is the largest waste generated by the construction industry. In the early 1990s, the European Community countries discharged 50 million tons of waste concrete annually, the United States 60 million tons, Japan about 12 million tons, and other countries are facing similar situations. Moreover, the amount of waste concrete is increasing every year, and it is estimated that the amount of waste concrete is three times as much as that mentioned above. < P > < FONT face = Verdana > Such a large number of concrete buildings will be demolished after reaching the end of their service life and become a large amount of waste, which will cause great environmental problems. In addition, a large amount of concrete waste will occupy a large number of valuable sites, especially in large cities where land and space are becoming more and more precious. The only feasible way is to use these wastes to make new building materials and realize the recycling of concrete materials. < P > < FONT face = Verdana > As a result, Dexin Real Estate Commercial Concrete Co., Ltd. has developed a pollution-free, high-strength and sustainable recycling concrete based on advanced technologies such as reprocessing, roasting and grinding of power plant waste fly ash and usable old concrete waste, combined with the new demand for concrete proportioning quality in modern mechanics. A new type of green recycled concrete. < P > < FONT face = Verdana > Mr. An Junping, the chairman of the company, graduated from the Department of Civil Engineering of Tsinghua University. He has been devoting himself to the research on the recycling of concrete waste for many years and has achieved remarkable results. In Anzong's words, the cooperation with Tsinghua University to develop green ecological building concrete is only the first step for the company to promote the revolution of green ecological building materials. < P > < FONT face = Verdana > The centennial Olympic Games call for the improvement of the whole nation's awareness of environmental protection. The great rejuvenation of the Chinese nation should not be accomplished on the basis of losing environmental costs. Although we have only made a small step forward, we firmly believe that our efforts will certainly promote the use of green building materials in the whole society.
