With the continuous improvement of living standards, people pay more and more attention to the living environment. However, some traditional building materials are made of chemical materials and contain toxic substances. This kind of building material continuously releases poisonous gas into the room, which is harmful to human health.

In addition, the innovative design of modern architecture includes both rational design and personalized design, and the functional requirements for materials are more and more diversified. These requirements for the innovation ability of building material production enterprises are higher and higher.

It is an inevitable trend for the development of construction industry to popularize and apply green technology, use new environmental protection building materials without pollution, pollution and radioactivity, and develop multi-functional building materials. New building materials have attracted much attention. The attention of all circles for new building materials can be fully reflected in the 6th China International Architecture Exhibition held recently. Recently, the 6th China International Architecture Exhibition, CO sponsored by China Architecture society, China Building Materials Federation and national building materials exhibition and Trade Center, and supported by International Association of architects and Asian Architects Association, was held in Beijing. As an important exhibition window and communication platform in the field of construction and building materials in China, the exhibition attracted more than 100 enterprises from all over the country, Hungary, Chile, the United States, Japan, South Korea, Australia and other countries and regions, with an overall scale of more than 10000 square meters.

The theme of the 6th architectural exhibition is "low carbon · design · innovation". The successful cases of architectural design and various new building materials in the exhibition are closely focused on the concepts of energy saving, environmental protection, low carbon and safety, highlighting the innovative features. At the exhibition site, visitors showed a strong interest in new building materials. They said that compared with traditional building materials, new building materials can not only reduce building energy consumption, but also make rational use of industrial waste. The new building materials not only will not pollute the indoor environment, but also benefit human health. It is helpful to improve the building environment. It can play the role of mildew proof, sound insulation, heat insulation, sterilization, temperature regulation, humidity control, light adjustment, flame retardant and deodorization. The production process of new environmental protection building materials will not pollute the environment and generate new wastes, and most of them can be recycled and reused, which is the inevitable demand of sustainable development of construction industry. In the exhibition, a variety of innovative new building materials occupy an important position. The building materials products mainly include decorative concrete, fireproof and thermal insulation materials, integrated energy-saving room, ceramic plate, functional glass, stone, etc. In recent years, with the development of China's construction and building materials industry, China International Architecture Exhibition has been constantly given new connotation and function. The new building materials products exhibited in the exhibition reflect that China's building materials enterprises have integrated the concepts of energy saving, low-carbon, environmental protection, green and safety into product research and development, market development and application, providing more material selection and material guarantee for the improvement of architectural design and building function.

All the materials enterprises, especially the new building materials enterprises, have integrated energy saving, low-carbon, environmental protection, safety and other elements of the times, and promoted the improvement of building functions with the improvement of material functions. Through the understanding of some participating enterprises, we can see that these enterprises which are committed to the production of new building materials will all have innovation throughout the process of production and R & D. These enterprises for product innovation can be summed up in the following aspects. First, develop new products. Taking Beixin building materials as an example, their practice is to lead the market with new products. Instead of meeting the market share of the original products such as gypsum board and rock wool, they have developed new plates and pipes according to the current construction requirements and green concept. These new products have attracted the attention of the construction industry when they enter the market. According to reports, Beixin building materials is mainly engaged in three aspects of circular economy, building energy conservation and housing industrialization. In recent years, the research and development of exterior wall panel and ultra quiet drainage pipeline has been increased. They use fly ash as the main material of the new exterior wall panel to replace the clay board, aluminum gusset plate, marble, this new type of exterior wall panel has larger specifications, more colors, more convenient construction, more reasonable cost, and higher cost performance. In the research and development of ultra quiet drainage pipeline, Beixin building materials has developed polypropylene drainage pipe, and its noise reduction effect is far better than that of PVC. Second, inject new elements into the product. At the exhibition, the reporter saw that a lot of artistic elements were injected into the decorative concrete lightweight hanging board produced by Beijing Baogui Shiyi Technology Co., Ltd., making the building facade full of vitality. In their own words, decorating lightweight concrete hanging boards has turned "armor" into "fashion". Third, the use of high-tech means to improve the scientific and technological content of the original products. By using the latest digital technology, Nanjing Beilida Industrial Co., Ltd. has produced GRC plates with non-linear shape, so as to expand the market and increase the economic benefits of the enterprise. Up to now, the benefit has been three times that of last year. The fair faced concrete protective coating of China Railway Decheng company and the light steel structure ASA board mosaic integrated energy-saving building of Beijing Huali United High Tech Co., Ltd. are also innovative achievements, which have good performance in energy saving, green and even safety. These products using concrete as raw materials all use fly ash, desulfurized gypsum and tailings and other wastes. In fact, new building materials have been widely used in the construction field, and will become the mainstream of the market in the future. New building materials have injected "fresh blood" into the construction industry.

The new building materials can not only solve the environmental pollution problem that people generally pay attention to, but also realize the rational utilization and recycling of resources, making the design and construction of buildings more perfect.
