Characteristics of building materials
The main difference between eco-building materials and other new building materials in concept is that eco-building materials are a system engineering concept, and can not only look at a certain link in the production or use process. The evaluation of material environmental compatibility depends on the interval or the boundaries set. At home and abroad, there are a variety of new building materials called ecological building materials, such as "ecological cement" produced by waste or urban garbage. However, if there is no systematic engineering point of view, building materials designed and produced by building materials energy-saving building materials may reflect "green" in one respect and "black" in other aspects, the evaluation is inevitably biased or even misleading.
