建筑垃圾（Construction waste） New methods for improving the recycling efficiency of construction waste With the progress of history, the harmonious development between concrete material, technology and ecological environment has become the common task facing mankind in the 21st century. The core of ecological environmental protection is to save resources and energy and reduce pollution to the environment. Concrete technology and ecological environment are the problems of coordinated development. With the improvement of national policy and the constant innovation of application technology, the regeneration of construction waste has created a new industry. The construction waste which is badly needed to be solved in China is dominated by the demolition of old buildings. Centralized and film demolition is one of the main features of the construction waste in China, which is large and concentrated in construction waste. Natural disasters such as earthquakes and mudslides are frequent, and the amount of non-normal construction waste is as large and complex. The damage will be greater if the construction waste is not disposed of in time. The use of construction waste, most of which is used for backfilling, and processing sand and stone aggregate. Processed into recycled aggregate is a social and economic benefit, with 95% utilization. Construction waste can produce recycled aggregate and used for building materials such as recycled brick, regenerated block and recycled concrete. It can be said that construction waste can be reused, turning waste into treasure, is a kind of resource. The study shows that the recycling of construction waste is technically feasible and mature. Henan sheng day environmental protection company in June to introduce mobile construction waste disposal of zhengzhou china-italy mining machine equipment and stationary brick making machine, after construction waste production of kerb brick, grass planting brick, color brick, square brick, permeable brick,
