Building materials and products are the important material technical basis for the development of construction industry. Of building materials and products in our country, from meet the building use function, the reasonable use of resources and energy saving according to local conditions, comprehensive utilization of industrial waste, application of new building materials.
A, tasks and goals
1. To lightweight, high performance concrete, composite, multi-function direction. By 2010, the average load bearing structure of concrete strength grade C40, established according to the strength, durability and other indicators of the concrete structure design and test a complete set of measures.
2. To develop the low alloy steel and efficient economical construction steel, build form a complete set of product structure, construction steel and metal products product technical standards generally reached the international level.
3. Further wall body reform, actively promote the new wall materials, limiting the use of clay brick. Wall reform must be promoted in order to improve the wall thermal insulation and waterproof performance, meet the requirements of energy conservation, reduce weight and enhance the adornment effect. To adjust measures to local conditions to rational utilization of local resources and industrial waste residue, promotion of clay brick, concrete small hollow block, etc., increase the varieties of wall.
4. Priority to the development of residential use of chemical building materials products, gradually developed a high grade product. The active adoption of plastic pipe (line), ground, wall materials, such as doors and Windows products and all kinds of decoration coatings, adhesives and sealing material. The positive development of decorative metal materials. Improve the quality of metal doors and Windows and building hardware, increase the variety of designs and colors. Rational utilization of wood (bamboo), development of composite wood products. Developing, high-grade glass, ceramics and other decoration materials and products and marble, granite products. Chemical products and building materials decorative materials during the "ninth five-year adjust product structure, build form a complete set of products series; To 2010 generally reached the international level in the 2010 s, the partial products close to or reached the international advanced level.
5. The positive development of inorganic and organic heat preservation, heat insulation, waterproof, plugging, fire prevention materials and products. "Key in the period of the development of new varieties, to establish and develop product series standards and application procedures, generally reached the international advanced level by 2010.
6. Strong transformation of sand and gravel aggregate, mining and processing technology of materials such as lime, gypsum, establish industrial supply base, according to the requirements of the quality of industrial products supply to households, reduce the use of the secondary processing. Mining and lightweight aggregate resources actively, accelerate the development of lightweight aggregate concrete products. From the governance environment and resources recycle double meaning full attention on the use of fly ash and other industrial waste. Attaches great importance to research the application technologies of demolition waste.
Second, the technology policy
1. Construction steel and metal products
(1) normal concrete with steel structure, while retain the original steel, the development of 400 ~ 550 million mpa grade steel welding deformation, make the product more hasten is reasonable.
(2) prestressed concrete structures with steel, the main development low relaxation strand wire, steel wire and high strength steel. "First development in the period of the stable performance of bits of j12 7 bits (4) and bits of j15 7 bits (5) 1570 ~ 1.86 billion mpa grade low relaxation of steel wire, steel wire. Actively use Ⅲ reinforcement, and open in the soil have erosion medium easy corrosion in concrete structure parts, using epoxy resin coated steel bar. Positive use of 650 ~ 800 grade cold rolled ribbed steel bar instead of cold drawing mild steel wire.
(3) steel structure steel, an increase of 345 million mpa grade Gao Ren, new steel grade weldable, corrosion resistance. The positive development of H, T shape and thin wall steel, closed sections and pipes. "To provide 445 million mpa grade in the period of the new steel and welding H, T payments; After 10 years with 735 million mpa grade multi-functional steel plate and the hot rolled H, T, and other payments; Gradually replace ordinary beams. Channel steel, Angle steel, reached the international standard of light thin wall steel standard series.
(4) the cold-formed thin-walled steel with pressed steel plate, the development of galvanized steel sheet and atmospheric corrosion resistance of coating of cold bending steel (aluminum), pressure plate. Priority to the development of roof and metope (including insulation composite panels) of new products, combined with the development of the new type of light steel structure, composite structure and door window, partition, ceiling, construction template, application of cold bending, pressed product standard series is established. The development of architectural curtain wall with aluminum. Aluminum alloy sheet and aluminum-plastic composite materials.
(5) improve the heating. Fluctuation water, gas, such as the quality and performance of construction metal pipe, providing series of products of different types of construction equipment are in need.
