摘要
在实验室对粉煤灰的各项技术参数进行了试验研究 ,揭示出粉煤灰的不同成分和形貌对其资源化特性的影响规律 ;初步完成了消除不利于粉煤灰资源化的有害成分———碳的优化实验工作 ;进行了脱炭粉煤灰混凝土配合比等方面的试验研究 ,并在路面修复工程中应用脱炭粉煤灰完成了试验路修筑工作。结果表明 ,将粉煤灰进行脱炭处理 ,应用于混凝土工程可以明显改善混凝土的工作性能 ,实际道路运营和技术性能符合路面工程的要求 。
Based on the study of technological parameters of coal fly ash in laboratories,the influencing regularity of different ingredients and forms of coal fly ash on its resourceful property was disclosed.The optimum experiment for geting rid of carbon harmfulness to resourceful property of coal fly ash was initially finished.The coopera ting rate of decarbonized coal fly ash concrete was researched and used to fulfil the pavement repair work.The result shows that decarbonized coal fly ash can obviously improve the working property of the concrete.Both practical road conveyance and technological function can satisfy the demands of pavement engineering.Both the economic and environmental benefit is enormous.
