| Why can the limited production, forbid to use the clay solid brick? |
|
Our country present building's main wall material was still the solid loam brick, was also the people often says “the red brick”, because its production use history was remote, therefore had “the Qin brick” the name. The no need to doubted, solid loam brick appearance to our country society and economic development very major function. However, because the solid loam brick's production needs to turn the sod takes the earth therefore, was specially the farming has created the very big destruction to the land. Generally produces the l hundred million bricks to every year turn the sod destroys the field the approximately 100 Chinese acres. Statistics indicated that the nation has the brickyard at present approximately 120,000, occupies a land area of 6,000,000 Chinese acres, every year bakees bricks more than 6000 hundred million, destroys the field to occupy a land area of more than 120 ten thousand Chinese acres. My city existing brickyard more than 160, occupy a land area of 22,000 Chinese acres, every year bakees bricks nearly 2,000,000,000, even if took the secondary ploughing measure also to destroy plants crops the nearly 1000 Chinese acres. At present, my city average per person farming already from early days of liberation approximately 4 Chinese acres, sharp decline to 1.28 Chinese acres. The population increases, the land reduces has become restricts my city society, the economical full scale development primary factor seriously. The practical protection land, protects the farming particularly, already was our basic state policies.
In addition, burn clay solid brick, because its equipment is crude, the craft is backward, both has wasted the massive energy, its emissions's mist and dust and has polluted the environment. After forbidding uses the clay solid brick, but massively uses each industry waste residue for example: Resources production and so on pulverized coal ash, cinder each kind of new wall materials. Therefore, the country to protect the land, the protection environment, to save with the comprehensive utilization resources, the promotion society, the economy and the technical full scale development, for the entire nationality's long-term benefits, from sustainable development's altitude, proposed first in the coastal city and the land resource scarce city, forbids to use the clay solid brick.
