With the rapid development of China's economy, people's awareness of architecture is getting higher and higher, and the requirements for safety, economy and comfort of the construction industry are also getting higher and higher。In the emergence of green buildings, new building materials have also emerged, including wall materials, insulation materials, waterproof materials and decorative materials。

Current situation analysis of new building materials

From the current construction cost of modern buildings in China, it can be seen that the cost of building materials accounts for about 50% of the total construction cost, and the quality and quality of building materials directly affect the quality of buildings。In recent years, with the change of architectural style and the improvement of architectural functions, building materials have also completed a new transformation, which can be summarized in four categories: new wall materials, new waterproof sealing materials, new thermal insulation materials and building decoration materials。

Compared with traditional building materials, the new building materials have a great improvement in material and functional division。From the functional division, can be divided into: decorative materials, insulation materials, curtain wall materials, sealing materials and waterproof materials;From the material division: can be divided into cement materials, glass materials, wood, steel, plastic and other various auxiliary hardware, non-metallic materials。At present, there are many new materials in use, such as: brick in wall materials, mineral wool board and glass wool in insulation materials, coil and coating in waterproof materials, coil and coating in waterproof materials, polymer composite materials, decorative materials and new RPC concrete。

现今，Insulation has been combined with energy saving and emission reduction measures，And is constantly improving，Step by step towards green buildings，Waterproof materials have departed from the traditional concept of simple waterproof，Has gradually formed product specifications and grade matching waterproof system;In terms of decorative materials，Has been refined into multiple wholes，It includes: curtain wall material, wallpaper, floor, ceiling and other materials with different properties，Fully reflects the diversity of materials。

The influence significance of new building materials

Compared with traditional building materials, the application of new building materials makes its strength increase, weight reduction, energy saving, more powerful function, and more in line with China's "basic national policy.。In terms of related performance research, new building materials have been greatly improved in terms of mechanical properties, durability and corrosion resistance。In the production process, the production of raw materials are fully utilized, and new processes and technologies are adopted to improve the performance of materials。

The application of new building materials

As the load-bearing structure of the building, the quality of the wall directly affects the stability and safety of the building。At present, there are many wall materials used in Chinese construction, such as clay hollow brick, clay brick, non-clay brick, aerated concrete block and light plate。At present, the walls of buildings under construction are mostly reinforced concrete materials, plastic materials and lightweight wall materials。This kind of material can improve the thermal insulation, sound insulation and safety performance of buildings in practical applications。Compared with the traditional wall building materials, the new building materials have the characteristics of light texture, small thermal conductivity, good thermal insulation performance, good water resistance, obvious sound insulation effect, easy processing, etc., while reducing the weight of building materials, it can also reduce the use of materials and energy consumption。

Application of thermal insulation materials

In recent years, major universities in China have conducted in-depth research on thermal insulation materials, and have successively developed polystyrene foam insulation board, rock wool board, glass wool, perlite insulation board, polyurethane foam board, perlite insulation board。Silicate load slurry and other thermal insulation materials of different materials。

At present, the development of insulation materials in the world is more than Xunshu, mineral wool and glass, mineral wool and glass wool materials occupy 50% of the application rate in the market field, foam insulation board occupies 40% of the market application rate, calcium silicate and expanded perlite insulation materials occupy 5% of the application rate。At present, the new insulation materials are steel mesh rock wool sandwich load board (GY board), silicon calcium insulation board, gypsum composite board and GRC sandwich composite insulation board 。Compared with similar thermal insulation materials, the new thermal insulation board has the characteristics of good thermal insulation effect, low material cost, simple construction technology, etc., but there are also defects such as low strength, poor construction performance and insufficient connection with the building matrix。

Application of waterproof materials

With the development of science and technology, the development of waterproof materials in China is relatively rapid, and the application range is also relatively wide, including Bridges, tunnels, water conservancy and hydropower, national defense and transportation industries, and the materials used in different industries are not the same 。The current waterproof material includes waterproof coil, sealing material and plugging material。

The application of concrete materials

As one of the most used materials of modern building materials, the quality of concrete directly determines the quality of buildings。RPC is a new cement base material with ultra-high strength, ultra-high toughness and ultra-high stability。Due to the superior performance of RPC reactive powder concrete, the compressive strength is 2 to 4 times that of ordinary cement, and the flexural strength is 4 to 6 times that of ordinary cement, which will be the main application material in the future construction 。At present, many universities in China have begun to deepen research on RPC reactive powder concrete, and many schools have prepared concrete with compressive strength of more than 200MPa。25mm thick RPC reactive powder concrete with the same strength is equivalent to 6Omm thick C40 concrete，Application of related admixtures in RPC，The internal structure of the concrete is improved，Improves its strength and durability，The parts with higher requirements for strength and related mechanical properties have strong practical value。

The development of new building materials

Under the conditions of China's rapid economic development, China's new building materials will make breakthroughs in ecological and intelligent, and reduce water pollution, chemical pollution, noise pollution and radioactive pollution as much as possible 。At the same time, the new building materials will also be combined with modern smart home and high-tech computer intelligent application systems to adjust the building intelligence and comfort, so that the building materials are more in line with the characteristics of modern urban buildings。

In addition, while developing new building materials and green building materials, it is necessary to comprehensively consider China's sustainable development path, reduce material consumption, reduce energy consumption and reduce pollution consumption。Breakthroughs in performance, use, functionality, and safety and comfort，Develop in conjunction with modern buildings of middle and high grade, collocation and standardization，Integration of microelectronics technology and high-tech production technology，To realize the control and improvement of new building materials，Make building materials more in line with world development trends and human survival needs。

With the rapid improvement of our economic level and building level, it is imperative to develop new materials。Building materials with excellent performance can not only improve the safety level of buildings, but also obtain greater protection in terms of environment and health。
