乡镇墙体材料革新“八五”期间的一个重要目标就是到“八五”末.乡镇新型墙体材料革新的比重要达到15%.到1993年底,乡镇新型墙体材料的比重约为7%.怎样才能在剩下的两年内实现新型墙体材料15%的目标呢?这就是要选好发展工业废渣(灰)砖(废渣、灰含量在30%以上.下同)这个突破口.之所以把发展工业废渣(灰)砖定为突破口,是因为废渣(灰)砖有许多优势:优势之一是将现有粘土砖企业改造为工业废渣
An important goal during the “8th Five-Year Plan” period of the innovation of township wall materials is to reach the end of the “Eighth Five-Year Plan”. The importance of the innovation of new wall materials in townships and villages has reached 15%. By the end of 1993, the proportion of new wall materials in towns and villages was about 7%. How can we achieve the target of 15% for the new wall material in the remaining two years? This is to select the breakthrough point for the development of industrial waste residue (ash) bricks (waste, ash content above 30%. Same below). The development of industrial waste ash (ash) bricks is a breakthrough because waste ash (ash) bricks have many advantages: one of the advantages is to transform existing clay brick enterprises into industrial waste slags.
