2003年6月30日,是我国墙体材料革新事业发展史上具有里程碑意义的时刻。这是170个大中城市禁止使用实心黏土砖的最后期限。为实现限时“禁实”目标,近几年,各地积极贯彻落实国家的有关政策,开拓思路,因地制宜,创造性地开展工作,取得了可喜的成绩。　　170个大中城市“禁实”期限的到来,并不意味着“禁实”工作的结束。实现“禁实”目标的城市应进一步巩固成果,未实现目标的更需继续努力。到2005年,所有省会城市要实现“禁实”,“禁实”工作还要向小城镇和农村推进。淘汰实心黏土砖,我们还有很长的路要走。　　为促进今后的“禁实”工作,推动墙材革新与建筑节能事业深入发展,本刊特编发一组报道,介绍部分省市的“禁实”经验。 June 30, 2003, is the moment of milestone in the history of the development of wall materials in China. This is the deadline for banning the use of solid clay brick in 170 cities. In order to achieve the goal of “banning the implementation of the ban for a limited time”, in recent years all localities have actively implemented the relevant state policies, opened up new ideas and carried out creative work in accordance with local conditions and achieved gratifying results. The arrival of the “banned” period in 170 large and medium-sized cities does not mean the end of the “ban on realism.” Cities that have achieved the goal of “banning forging ahead” should further consolidate their achievements and need to continue their efforts if they fail to achieve their goals. By 2005, all provincial capitals will have to be “banned” and work on “banning” must be pushed forward to small towns and rural areas. Out of solid clay brick, we still have a long way to go. In order to promote future “banning” work and promote the further development of wall materials innovation and building energy conservation, we specially compiled a series of reports introducing the experience of “no-clean” in some provinces and cities.
