今年二月召开的全国建材局长会议指出墙体材料改革是一项十分紧迫而艰巨的任务,并强调发展节能、节土、利废的新型墙体材料,今年二月末,辽宁省人民政府又批发了“辽政发[1990]15号文”《关于限制毁田烧砖发展新型墙体材料的通知》,通知中明确要求积极发展并强制推广轻质、利废、节能的墙体材料。粉煤灰是电厂排出的工业废渣,就朝阳热电厂来说每年要排放粉煤灰近十万吨之多。我们以该电厂粉煤灰为主并掺加其它工业废渣进行了蒸压制砖的研究,取得了较好的结果。
The National Building Materials Directors’ Meeting held in February this year pointed out that the reform of wall materials is a very urgent and arduous task, and emphasized the development of new wall materials that are energy-saving, soil-saving, and waste-disposal. At the end of February this year, the People’s Government of Liaoning Province has also The “Liao Zheng Fa [1990] No. 15 Text” “Notice on Restricting the Use of Burnt Bricks to Develop New Wall Materials” has clearly stated that it is required to actively develop and enforce the promotion of lightweight, profitable, and energy-saving wall materials. Fly ash is the industrial waste discharged from the power plant. As far as the Chaoyang Thermal Power Plant is concerned, nearly 100,000 tons of fly ash will be discharged every year. We used the power plant fly ash as the main component and added other industrial wastes to carry out the research on steamed compacted bricks, and achieved good results.
