In peopleundefineds impression, brick kiln sky is full of smoke, taste pungent. However, 139 clay brick enterprises in Changsha have been outlawed according to the law, instead of shale

In peopleundefineds impression, brick kiln sky is full of smoke, taste pungent. However, 139 clay brick enterprises in Changsha have been outlawed according to the law, instead of shale, fly ash, residue as raw materials, coal gangue or natural gas as fuel new wall materials. Today, the municipal construction committee on further strengthening the construction of new wall materials and green building materials to promote the application of special sessions and mobilization deployment. The reporter learned that the committee has recently issued a notice on further strengthening the popularization and application of new wall materials, with a view to phasing out and replacing clay products. By 2020, the proportion of new types of wall materials used above plus or minus zero in construction projects in Changsha will reach 95 percent.

The proportion of new wall materials used in Changsha will reach 95% by 2020.

According to the responsible person of the Office of Building Energy Saving and New Wall Materials Management Office of the Municipal Construction Committee, the new wall materials are made from non-clay materials such as shale, industrial waste residue, solid construction waste, etc., and have light weight and high strength. Heat insulation and other excellent properties of the wall materials.

The proportion of new wall materials eliminated from clay products in Changsha, Hunan Province will reach 95%.

Changshaundefineds wall modification work began in the early 90s of last century. After more than 20 years of effort, the application ratio of new new wall materials in Changsha has been increased from 4.3% to 92% in 2017. The development of wall materials from "real to empty" to solid waste, from block to plate, has been formed in three categories of bricks, blocks and plates, and high added value. Products are constantly emerging, assembly wall materials gradually become a system, green building materials product production enterprises have reached 15, accounting for 60% of the province, and gradually realize the leap from new wall materials to green building materials.

According to statistics, by the end of 2017, the production capacity of the new type of wall materials enterprises in the city will reach 4.2 billion standard bricks. Based on the annual output of 3 billion, it is estimated that 4850 mu of soil can be saved each year, 186000 tons of energy can be saved, 428000 tons of carbon dioxide greenhouse gases will be reduced, and 4700 tons of sulfur dioxide will be reduced. Good social and environmental benefits of 2.25 million tons of solid waste are used to contribute to energy saving and emission reduction in Changsha.

According to the notice, in order to further consolidate the achievements of the work of "City viscosity restriction, county town ban," and prevent the application of clay products from rebounding, Changsha City will further strengthen the promotion of new wall materials. And form design review-construction supervision-completion of the closed supervision and management system.

At the same time, Changsha Energy Saving New Wall Office will carry out on-site verification of all the projects under construction in the city, and the quality supervision department will not complete and accept the new wall materials for the record of completion and acceptance for those projects that do not use the new wall materials as required. The office will also simplify the procedures and strive to build a "new type of wall material application on the Internet" information system this year, which will be used to collect the production and application of new wall materials in the whole city, and to analyze the application requirements and development trends.

Tang Wei, an investigator of the Changsha Municipal Housing Construction Commission, said that the next goal of Changsha is to realize the product wall material combined with the assembly building, green building materials combined with green building, self insulation wall material combined with building energy conservation, integrated waste wall materials with green development, towards green, low carbon, recycling, conservation of resources and energy, protection of the environment And the sustainable development of the road healthy and steady development.
