株州市年排粉煤灰、渣73万吨,最高利用量,占灰渣年排总量的53.3%。笔者在前期利用石灰窑二氧化碳气及窑的余热,试制碳化粉煤灰砖,并进行了工业性批量生产。其生产碳化粉煤灰砖3454万块,折合建筑面积11万多平方米。经过几年观察,未发现有破坏现象,砌体部位完整,尤其是处在潮环境部位的 Zhuzhou City discharges 730,000 tons of fly ash and slag each year, with the highest utilization amount accounting for 53.3% of the total annual ash emissions. The author used the lime kiln carbon dioxide gas and the waste heat of the kiln in the early stage to trial-produce carbonized fly ash bricks and carried out industrial mass production. It produces 34.54 million pieces of carbonized fly ash bricks, equivalent to a building area of ​​over 110,000 square meters. After several years of observation, no damage was found and the masonry parts were complete, especially in the tide environment.
