传统墙体材料的生产对国土耕地的影响

墙体材料是我国建材工业的重要组成部分,其产值约占建材工业总产值的三分之一。传统墙体材料以实心粘土砖为主,它最早兴起于战国时期,一直延用至今。目前,我国91％以上的墙体材料是实心粘土砖,其中90％是由产乡镇企业生产。这种以实心粘土砖为主导、小企业为主体的生产格局,带来了产品结构不合理、能耗大、占地多、毁田严重、运输量大、不能适应建筑业技术进步要求等突出问题。以调整产品结构,节能降耗,节地利废,满足建筑功能要求为目的的墙体材料改革势在必行。

INFLUENCE OF PRODUCTION OF TRAKITIONAL MASONRY MATERIALS ON NATIONAL CULTIVATED LAND

Masonry materials is an important part of national building materials industry. Soild clay brick is the main kind of traditional masonry materials, which rose in the Warring States and is still used up to now. The productive pattern of taking solid clay brick and small enterprises-as dominant leads to some prominent problems, such as the unreasonable product structure, the heav y energy consumption, the serious farmland damage, the unfitness in with the needs of technical progress. So the impvations of masonry materials are inoerative.
