New building materials, including emerging materials and products, including new products, the original material. New building materials are different from the traditional brick and gray gravel and other building materials, construction materials of new varieties. From the functional point, a wall materials, decorative materials, doors and windows materials, insulation materials, waterproofing materials, bonding and sealing materials, and its support of the various metal parts, plastic components and accessories and materials. from the material on the points, not only of natural materials, as well as chemical materials, metal materials, non-metallic materials and so on. For Jianzhu industry, the new building is a broad concept, cement, glass, steel, wood raw material for four new products; Niantu hollow bricks, all kinds of aerated concrete products various blocks of new products; inorganic non-metallic materials used in construction of various new products are new building materials and the introduction of various new raw materials, production of various building products, and so are new building materials areas.

New building materials are lightweight, high strength, insulation, energy and land, decorative, and other fine features. Using new materials not only greatly improved the housing function, but also more modern inside and outside the building to meet the aesthetic demands of the people; some new building materials can significantly reduce the weight of buildings, structures for the promotion of light to create the conditions to promote the building of modern construction technology, greatly speeding up the building speed.

From the building structure is concerned, the walls are the most important part of the building, relationship building is a key factor in performance and service life, and new wall construction materials used in large part to promote energy efficiency, reduce the weight of buildings, design and improving the housing construction has important economic significance. new building materials have to construct a new, performance, features all the characteristics of the building with energy-saving insulation, comfortable and beautiful, safe and durable features, but also facilitate the construction of modern . the use of new wall materials, but also can increase the area of construction used to reduce the weight of the building, and enhance anti-development capacity. Therefore, the development of new building materials industry, to improve the lives of urban residents in China for energy, land and resource comprehensive used to play a positive role.

A new wall materials for the importance of reducing the weight of buildings
In addition to building vertical load borne by the live load, the main weight bearing and non load-bearing structural components of the weight and the weight of decorative materials. In order to optimize the building structure must be designed to reduce the weight of these components, the potential use of a new building materials in the pipeline.

First of all, reduce the load-bearing structure of its own weight. Building weight bearing structures in building the proportion of the total weight of the different structural systems due to different, generally about 75% of the total weight. Therefore, high-rise buildings to reduce the weight bearing structure is necessary . can improve the strength of materials, reduced component size and reduce the material density cross-section method. In rich countries, steel production, construction steel structure high-rise building is often used, because the steel of high strength, light weight, avoid thick beam pillars, but also save a lot of use of the area. If high-rise building with reinforced concrete structure, we must attach importance to high-strength lightweight concrete, to reduce the load-bearing structure of its own weight. At present, international and domestic purposes on the development of high-strength lightweight concrete, One is to high grade cement, the second is to develop artificial lightweight aggregate, sand and gravel in place of ordinary concrete aggregate, lightweight aggregate, including man-made artificial lightweight coarse aggregate and fine aggregate of two artificial light. which, artificial lightweight coarse aggregate expansion of a calcination shale, clay and slate, with mechanical or water-jet expansion of production of slag and sintered fly ash. which, to the formation of calcined shale shale expansion TAO clay tablets and sintered to form ceramic clay ceramic and fly the most widely used.

Makes use of new wall materials in terms of section size of structural members or units have greatly reduced the bulk density, not only to reduce the weight of buildings, and optimize the structure design and improve the construction economy, its structure, reduce weight, and with good economic results .

Second, to reduce non-load-bearing weight of components and decorative materials. In addition to high-rise buildings to reduce weight bearing structure, but also improve the non-load bearing components, these components play only insulation, insulation, air and sound insulation effect, so the non-load bearing components but also to promote lightweight materials. If aerated concrete, lightweight concrete, gypsum board, asbestos, slag wool board, plastic board. such as the use of aerated concrete is a form of industrial waste light porous low density materials, products, low cost, good insulation properties, but also significantly reduce the weight of buildings, 240 mm thick aerated concrete wall of the heart is equivalent to 640 mm thick brick wall of the insulation effect, using it to make the external wall and internal wall both energy-saving, reduce the weight, thus optimizing the structure design. a new type of gypsum board, asbestos and plastic sheets have many excellent features a unique, light weight, high strength, good plasticity, corrosion resistance, good insulation, etc. Thus in high-rise building on the more widely used.

2 at this stage of development of new wall materials Status and Prospects
Industrial countries, experience shows that to a certain period of social development, the inevitable progress of the construction industry requires the building construction materials is conducive not only improve the function, but also for its construction can be easily mechanized and improve construction efficiency. The development of new building materials is the development and expansion of building pillar industry of building materials, industrial structure adjustment, and foster new economic growth point, an important strategy to achieve sustainable development initiatives. to develop new wall materials, building materials industry, the adjustment of industrial and product structure and improve the industry's overall technological level, quality and competitiveness play a very important role, new wall materials as a pillar industry of new building materials of economic growth and new industries will become increasingly showing its important position to play a greater role. development of new wall construction material is economic development, construction progress and improved living standards in an objective need.

Rapid development of new wall materials, production of new wall materials in 1987 as 18.45 billion standard bricks, and by 2008 had grown by more than 10 times, new wall materials in the proportion of the total wall materials increased more than 30%. more varieties of new wall materials, including bricks, blocks, plates, such as hollow clay brick, clay brick mixed waste, non-clay brick, building blocks, aerated concrete, lightweight sheet metal, composite board and the new derivative products, but the use of a smaller scale, in the wall material accounts for the overall proportion remains low. only to promote the rapid development of new types of building materials to local conditions in order to change the irrational product mix of wall materials, save energy, protect farmland use of industrial wastes, and promote the purpose of building technology.

After nearly 20 years, the introduction of foreign advanced production technology and equipment, wall materials in China has embarked on many varieties of industrial development path, initially formed a wall plates based system, such as concrete hollow block, paper gypsum board, fiber cement sandwich panels, but on behalf of a variety of wall materials in light of modern standards board, the proportion of composite panels are still very small compared with the industrialized countries, is still very backward, we use the product quality is not high, small-scale manufacturing enterprises, backward technology and equipment, supporting poor.

Development of new wall materials, we must first establish the new wall materials leading products. At present, new wall material has formed the main masonry materials, sheet metal shop for a variety of products for the coexistence of the product structure. Analysis of the current The structure of new wall materials state, bearing the load-bearing wall materials should increase the development of hollow brick concrete blocks, non-load-bearing material, to develop light-weight sheet. different regions should be based on local resource conditions and construction needs, construction a number of advanced technology and equipment products in the market have the ability to multi-purpose, high-quality, low-power product line of new wall materials. in the country have goals to build a number of supporting the production of energy, matching supply with a fixed scale of new wall materials base, and vigorously promote the development of new wall materials. the development of new materials, it has been over the scope of the industry, far beyond the significance of the development of new products generally, it is a systematic project, to play new material Research, development, application, design, construction, management, distribution and other relevant departments of the role of co-operation in the housing industry in this new economic growth point of the promotion, co-casting the bright future of new building materials.
