The development of new building materials and products is a requirement of the sustainable development strategy Sverige

For China, where the per capita share of resources such as energy and arable land is only 1/4 of the world average, the coordinated development of the national economy and society with resources and the ecological environment is more important and urgent.At present, China's clay solid bricks still account for nearly 80% of the total production of wall materials. The problems of high energy consumption, land destruction, and pollution are very serious. Each consumes 2.2 billion tons of clay resources, and the brick-making destroys about 120,000 mu of land, consumes 82 million tons of standard coal, and emits a lot of dust and carbon dioxide at the same time.Therefore, the development of organically reported building materials and products is related to the implementation of our country's sustainable development strategy, and it is also related to the healthy development of the building materials industry. With the development of the national economy and the gradual improvement of people's living standards, people's requirements for living and working places are also constantly increasing.The experience of many countries has proved that it is an inevitable trend of economic development and social progress.The progress of the construction industry does not require the quality and function of buildings to be perfect, but also requires them to be beautiful and harmless to human health.This requires the development of multifunctional and efficient new building materials and products, and only in this way can they adapt to the requirements of social progress.The use of new building materials and products can significantly improve the function of the building, increase the use area of the building, improve the seismic resistance, facilitate mechanized construction and improve construction efficiency, and under the same circumstances can reduce the construction cost.Practice in Tianjin, Chengdu and other cities has proved that under the same conditions, the use of new building materials and products can increase the effective use area by nearly 10%, reduce the weight of the building by more than 40%, and effectively improve the seismic resistance.According to the annual completion of 10% of the 240 million square meters of urban residential buildings, new materials are used, which can increase the effective use area by about 20 million square meters per year, and the comprehensive cost can be reduced by about 4%-7%.In addition, the development of new building materials has also had a significant effect on environmental protection and comprehensive utilization of resources. Taking the "Eighth Five-Year Plan" period as an example, the development of new wall materials alone has saved more than 22 million tons of standard coal in production energy consumption and building heating energy consumption, reduced land destruction by about 150,000 mu, and used 95 million tons of industrial waste residue to reduce carbon dioxide emissions by 23 million tons.As the building materials industry with the strongest correlation with the construction industry and 70% of its products are used in the construction industry, the development of new building materials and products is incorporated into architectural design and construction regulations to promote the application of new construction materials and promote the development of new building materials.The promotion and application of new building materials not only has considerable social benefits, but also significant economic benefits.For example, the cost of applying new thermal insulation materials to buildings to save energy is much larger than the increased cost of replacing clay solid bricks with new building materials.Therefore, the development of new building materials and products is an important part of social progress and improving socio-economic benefits.
