我国粉煤灰砌块技术研究现状

摘要

Fly ash is widely used to produce hollow block. Combined with the physical properties and chemical properties of fly ash, the property and study status of the cementitious material and aggregate used in fly ash block are introduced with fly ash activation methods. The performance study con-ditions of fly ash block are summarized and the current technological difficulties and development trend of fly ash block are analyzed.%利用粉煤灰制作空心砌块是粉煤灰的重要用途之一。该文结合粉煤灰的物理和化学性质，介绍了粉煤灰砌块中使用的胶凝材料和骨料的性质与研究现状，以及粉煤灰活性激发方法；并对粉煤灰砌块性能的研究情况进行了总结，分析了粉煤灰砌块目前存在的技术难点和发展方向。
