As one of the pillar industries of the national economy, in recent years, the construction industry has grown by leaps and bounds. At the same time, more and more construction waste has been produced. An invention patent of China National Institute of Building Materials Science (hereinafter referred to as the “Construction Materials Instituteâ€), Cement New Material Institute, can use environmentally-friendly exterior wall hanging panels for building construction waste.
It is understood that this invention patent is entitled “Environmentally Friendly Exterior Wall Hanger with Construction Waste and Its Preparation Methodâ€, which can not only deal with a large amount of construction waste, but also can reduce the amount of cement used by 10%-20%, partially or completely replace the sand. Its products are in full compliance with the "Concrete Exterior Wall Hanging Plate Standard", and are significantly higher than the standard requirements in terms of anti-folding and other performance indicators. At present, the environmentally friendly external wall hanging board produced by the patented technology is nearly 500,000 square meters. It has been gradually applied in large scale in the construction of new earthquake-resistant and energy-saving houses in Beijing, Shanxi, Hainan and Sichuan. (Reporter Chen Yu Li Qinghai)
