In order to implement the relevant requirements of the "Guiding Opinions of the State Council on Dealing with the Paradox of Severe Overcapacity" (Guo Fa [2013] No. 41) and the "Green Building Action Plan" (Guo Ban Fa 〔2013〕 No.1), deepen the linkage between upstream and downstream and promote high Performance of concrete to promote the application of the Ministry of Industry and Information Technology, the Department of Materials Industry in conjunction with the Housing Department of Urban and Rural Standards and Standards Department on March 4 in Beijing organized a high-performance concrete to promote the application of technical guidance group formation and the first working meeting. The meeting announced the establishment of high-performance concrete to promote the application of technical guidance group to introduce the promotion and application of high-performance concrete work to discuss "on the promotion and application of high-performance concrete a number of opinions (draft)" "ready-mixed concrete green production and management of technical regulations" "high Performance concrete application technology guide "and" high performance concrete evaluation criteria "and other documents, participants from different angles to promote the application of high performance concrete to make recommendations and opinions. The meeting held that the promotion and application of high-performance concrete is of great significance: First, to strengthen energy-saving emission reduction, prevention and control of air pollution an effective way. By promoting high-performance concrete, cement clinker consumption can be reduced, cement production can be reduced, resources and energy consumption can be reduced, utilization of recycled aggregates such as tailing sand and construction waste can be enhanced, energy saving and emission reduction can be promoted, and a recycling economy can be developed. Vigorously develop commodity concrete, concrete prefabricated components, all kinds of engineering concrete, etc. can greatly reduce construction dust. The second is to improve the quality of the building, to extend the life of the building, enhance disaster prevention and mitigation capabilities. High performance concrete with excellent durability, to ensure that the general building without major repairs to achieve more than 50 years of service life, specially designed high performance concrete, service life of up to 100 years. Third, promote the structural adjustment of cement industry. Promote the use of high performance concrete will not only bring progress to the construction industry, but also bring profound changes to the building materials industry. By adjusting the consumption structure of concrete, the structure of cement products will be driven to optimize and the cement will be highly marked and specialized. Pan Aihua, deputy director of the Department of raw materials pointed out the next focus of work: First, to strengthen the basic research of high-performance concrete. Improve the relevant standards and norms to promote the further convergence of product standards and application specifications. The second is to strengthen the raw materials industry management. Strengthen the cement, gravel, admixture and other industries planning and guidance. Research into the introduction of industry access, carry out green production assessment, enhance the level of concrete production, encourage enterprises to mergers and acquisitions, and improve industrial concentration. Third, to promote the integration of the two. The use of information technology to improve the level of control of concrete production, the use of GPS, cloud computing and other advanced technologies to enhance concrete production, transportation, construction and other aspects of the level of information. At the same time, high-performance concrete is an important variety of green building materials, Pan Aihua also briefly introduced the green building materials related work. Nearly 100 experts and experts from the production of concrete and raw materials, architectural design and construction enterprises, and related associations, research institutes and universities attended the meeting.
Lost wax casting also is called investment casting which is a kind of precision casting process.Through dewaxing to get the shell moulding,then shell would be poured the liquid metal to fullfill.The final parts would be more precision in size and nice roughness in surface.The widely range of material could be made by this casting process including ferrous metal and None ferrous metal.
The advantages of investment casting as below:
1.The fine surface with roughness of Ra6.3
2.More accuracy dimension around GCT7
3.Vast size ranges
4.Fast production process
5.No limitation in metal material
6.Low cost in moulding pattern
