随着国家禁止使用粘土实心砖政策的出台 ,我国许多粘土实心砖企业必须另起炉灶 ,转产符合国家产业政策的煤矸石、粉煤灰砖 ,或者生产以空心砖为代表的新型墙体材料。在发达国家建筑业采用以空心砖为代表的新型墙材已达到百分之百。而我国奋斗了十几年 ,才使我国有上千年历史的 With the introduction of the policy of prohibiting the use of clay solid bricks, many clay solid brick enterprises in China must start their own businesses, convert coal gangue and fly ash bricks that meet the national industrial policy, or produce new types of wall materials represented by hollow bricks.
