据有关方面报道,上海去年全市排出粉煤灰量90多万吨,利用了60多万吨,其中大部分用于生产水泥和加气混凝土、砌块、砖等建筑材料,还有一部分作筑路材料和水泥、黄砂的代用品,取得了明显的经济效果。市里规定利用粉煤灰不收费,今年又批准了几个粉煤灰建材产品实行减免税。上海市有关部门决定逐步建设闵行和宝钢电厂两个粉煤灰综合利用基地。市经委已批准在闵行新建年产1亿块砖的粉煤灰砖厂,投资1000万元,每年可吃灰18万吨。该厂的设计已委托东北建筑设计院承担,筹建和设计工作正在紧张进行中。
According to reports from relevant authorities, Shanghai exported more than 900,000 tons of fly ash last year and used more than 600,000 tons, most of which were used to produce cement and concrete for aerated concrete, blocks, bricks, etc., and part of it was built. Road materials and substitutes for cement and yellow sand have achieved significant economic results. The city stipulates that there is no charge for the use of fly ash, and this year it has approved a number of fly ash building materials products to implement tax reduction and exemption. The Shanghai Municipality decided to gradually build two fly ash comprehensive utilization bases for Minhang and Baosteel Power Plants. The Municipal Economic Commission has approved the construction of a new fly ash brick factory with an annual output of 100 million bricks in Minhang, with an investment of 10 million yuan and an annual consumption of 180,000 tons of ash. The plant’s design has been entrusted to the Northeast Architecture Design Institute, and preparation and design work is underway.
