The state promotes energy saving refractory materials used to promote the re-use of source
In recent years, China's urban behind sustainable development, the prevalence of the phenomenon of large demolition and construction, on the one hand is facing resources, energy shortages, on the other hand there is also the problem of low utilization of building materials and then bricks and other waste. In fact, the vast majority of waste materials can be reused. How to change the existing waste materials management, promote re-use of waste materials is one of the important issues of the full realization of the construction of sustainable development must be addressed.

To further promote the reform of wall materials, saving energy and resources, the effective protection of arable land and the environment, and promote comprehensive utilization of resources, the National Reform Commission announced the promotion of energy-saving emission reduction targets and tasks of real

Now, China will gradually restrict the use of solid clay bricks article or disabled in hundreds of cities and related county. By the end of 2015, more than 30% of the country's cities to achieve "limited sticky", more than 50 percent of the county

City to achieve "real ban."

Waste recycled aggregate concrete bricks can be prepared. In other countries, the use of waste materials for preparing recycled aggregate has formed a complete process system. Reference to foreign processing technology and I

The actual situation in the country, using its technology a waste brick aggregate, some of which the residual pieces of hardened concrete, recycled low strength concrete. Waste brick aggregate compared to natural aggregate, its surface

Relatively coarse, high friction, the performance of liquidity, poor slump, but the aggregate surface roughness, increasing the mixing pouring resistance, water retention and therefore better cohesiveness. Is also abandoned bricks

Replace river sand as fine aggregate as well as the production of wall materials. Firebrick abandoned after still has a certain strength, it can be used for the production of wall materials. Abandoned bricks can be used for road material.

At present, China construction waste recycling relatively low level, and then generate the actual use of the product range is very limited. One very important reason is the lack of building materials, waste recycling technology

Surgery, but also the lack of promotion for the consumer market, cost and performance is an important factor restricting the development. Abandoned building materials, especially bricks of recycling technology in the country is still in no

Mature stage, but also it requires a lot of testing and research to improve and upgrade their technical feasibility, and gradually perfect way to re-use waste materials, technology and quality.
