Abstract: In the rapid development of economic construction at the same time, the increasingly prominent ecological and environmental problems are more and more highly valued by all walks of life, among which, the traditional construction industry as a high-pollution, high-energy industry, if it is the key to reduce energy consumption. This paper mainly analyzes the importance of the application of building materials, at the same time, the development and application of building materials in the construction industry are analyzed, and finally put forward relevant suggestions to promote the development of building materials.
1. Development of building materials application
The development of building materials is the premise of transforming traditional building materials
In the new era, China’s traditional building materials industry as a high-consumption industry still occupies a dominant position in the market. According to the statistics of various energy consumption, the total energy consumption of building materials still occupies the first place in the total energy consumption of the country. The tense situation of various energy sources has gradually become a prominent problem restricting the healthy development of society. Therefore, how to effectively reduce energy consumption, reduce pollution emissions, maximize energy efficiency, and protect the ecological environment has become an important topic that governments at all levels need to further study and solve.
1.1 Development status and sustainable development requirements of building materials
Due to the use of a large amount of industrial waste, building materials reduce the consumption of natural resources, and play a positive role in promoting the sustainable development of the economy and society. In the production and production process, it will not only cause the problem of environmental pollution, but also help to improve people’s physical and mental health, improve the building function, play the role of anti-mildew, sterilization, sound insulation, heat insulation, humidity control, dimming, temperature regulation, flame retardant, deodorization. As people become more environmentally conscious, new requirements are placed on the construction industry: we want houses to be energy self-sufficient and we want to add power to the grid. The emergence of new building materials can make this hope a reality. It can not only solve the problems related to environmental pollution, but also realize the recycling of resources, realize the reasonable allocation and sustainable use of resources, and meet the requirements of sustainable development of society.
1.2 The development of building materials effectively alleviates the situation of energy shortage
From the perspective of the market, the construction industry is the end user of the building materials industry. In China, the annual housing area is 1.6 billion square meters, of which more than 90% of the buildings are still high-energy buildings. At the same time, building energy consumption accounts for nearly 30% of the country’s energy consumption, and the energy consumption per unit area is much higher than that of other countries. It can be seen that the development of building materials to ease the situation of energy tension is urgent.
2. Development and application of building materials in the construction industry
2.1 Wall Building Materials
In the new period, the development of building materials in our country is very rapid, all kinds of wall building materials, such as clay hollow bricks, clay bricks, light board, aerated concrete, blocks, compound board, etc., have been put into practice. The proportion of new wall building materials in the total area of the wall has increased, and the grade and level and scale of the leading products in the construction of each production line are constantly increasing. Focus on the development of hollow brick using waste slag content, high porosity, high insulation performance, high arc bearing porous brick, concrete block wall wall water concentrated in the double hole or porous insulation bearing block and block wall development, focus on extrusion light perforated plate production mechanization development, with packaged insulation or decorative plate composite wall, And with the promotion and application of light steel structure system construction ministry, the development of various prefabricated plates.
2.2 Application of insulation building materials
Insulation building materials is a kind of building materials, with the improvement of building performance requirements, insulation building materials are more and more welcomed by people. It has good thermal insulation performance, can increase the external wall insulation of the building, improve the performance of modern buildings, and save energy consumption. In modern architecture, the application of insulation materials can better meet the needs of modern architecture. Such as insulation board, can be used for building insulation and external insulation building materials, can be used for building wall insulation. In modern buildings, the construction unit according to the needs of modern construction projects reasonable selection of insulation building materials, calculation of thermal conductivity of insulation building materials, the development of insulation building materials application scheme.
2.3 Polymer chemical building materials
At present, the most active field is the research of fluorine resin and silicone modified resin. In foreign countries to compete in building waterproof sealing building materials, product update fast, the polymer resin modified asphalt as the development direction of basic building materials and polymers; Asphalt base, glass fiber or resin-based fiber reinforced film and television base development; The development of roof waterproof structure is from a number of single, two sides; The development of hot construction technology, hot melt adhesive at room temperature, self-adhesive, mechanical fixing, etc.
2.4 Waterproof sealing building materials
There are five main types of building waterproof building materials in China: linoleum, sealing building materials, building waterproof coatings, modified asphalt linoleum, synthetic polymer waterproof coil, leakage plugging and rigid waterproof building materials. The emergence of these products has completely eliminated our paper tire linoleum. For example, polytetrafluoroethylene (PTFE) is a surface plastic film building material. It has excellent fire resistance, wind resistance, ductility and water resistance. When the fire spreads, it will melt and burn, effectively improving the safety of the building.
2.5 Ecological concrete
Ecological concrete can be divided into environmental ecological concrete and biological ecological concrete. Environmental ecological concrete mainly has the following advantages: ① Environmental ecological concrete can reduce the load on the environment during manufacturing. This technology is mainly implemented through the reuse of solid waste; ② Can reduce the load on the environment during use. For example, by increasing the performance of concrete or strengthening the design to improve the service life of the building, thus effectively saving resources and energy; ③ Concrete itself can reduce the load on the environment. It can reduce the amount of raw materials. Biological concrete mainly refers to concrete that is in harmony with animals and plants. For example, plant-type ecological concrete mainly uses the porous characteristics of concrete to make plants breathable and penetrate the nutrients needed by plants. According to this growing plant, it can be grass or low shrubs and other plants, mainly used for greening and beautifying the riverbed.
3. Proposals to promote the development of building materials
Waterproof building materials are an important building materials required by the construction industry and other industries, and are an important component of building materials in the construction industry. Nowadays, with the rapid development of China’s economy, various industries have stricter requirements for building waterproof building materials, and higher quality building waterproof building materials should be used in important industries such as Bridges, tunnels, national defense, agriculture and transportation, as well as related fields. In recent years, China’s economy has been rapid development, waterproof building materials are also in the stage of rapid development. However, there are still many shortcomings, such as the unreasonable structure of the product and the generally low quality of the sub-products, too many fake and shoddy products, and the related construction technology needs to be improved. As an emerging industry in China, building materials industry has become a new economic growth point in building materials industry.
