Materials are the material basis for human survival and development
Materials are the material basis for human survival and development. In the 1970s, people regarded information, materials and energy as the three pillars of contemporary civilization. In the 1980s, the new technology revolution, represented by the high-tech group, juxtaposed new materials, information technology and biotechnology as an important symbol of the new technology revolution. This is mainly because materials are closely related to national economic construction, national defense construction and people's life. In addition to its importance and universality, materials also have diversity. Due to the variety of materials, there is no uniform standard for classification methods.
With regard to the development mode of ecological building materials and the improvement of environmental coordination, Professor Yoichi Mimoto, a Japanese scholar, summarized four types of innovative methods and their respective evaluation of the contribution to environmental coordination, namely, product improvement, redesign, functional innovation and system innovation. System innovation has the greatest impact on the improvement of environmental coordination, takes the longest time, and is not difficult to understand. System innovation is also the most difficult, while product improvement is relatively simple, and the improvement of environmental coordination is relatively small. It should be pointed out here that for a certain material, the development of ecological or environmental coordination does not necessarily follow these four orders.
There are still some difficult questions to answer about the development strategy of ecological building materials. For example, environmental coordination and use performance do not always coordinate and promote each other.
The author believes that the development of ecological building materials should not be at the expense of excessive sacrifice of performance. However, the requirements for the use performance of eco-building materials are not necessarily high performance, but the excellent performance or the best use performance that meets the use requirements. Low-performance building materials are bound to affect durability and use functions.
If LCA method is used for evaluation, sacrificing performance for energy conservation and waste utilization in the production process does not necessarily improve the environmental coordination of materials.
