Characteristics of building materials

The main difference between ecological building materials and other new building materials in concept is that ecological building materials are a concept of system engineering, which can not only look at a certain link in the production or use process. The evaluation of the environmental compatibility of materials depends on the investigated interval or the set boundary. The finishing touch at home and abroad is the emergence of a variety of new building materials called ecological building materials, such as "ecological cement" produced from waste or urban garbage. However, if there is no viewpoint of system engineering, the design and production of building materials may reflect "green" in one aspect and "black" in other aspects, so the evaluation is inevitably biased.
