Optimal particle size distribution (with maximum bulk density) was obtained according to Dinger-Funk Equation, and actual particle size distributions of each fly ash cement were calculated based on the testing results made by LS-230 granulometer.

• 根据Dinger-Funk的数学模型可得出粉体最佳颗粒群分布(即堆积密度达最大时的分布),并通过水泥与粉煤灰激光粒度检测结果计算各粉煤灰水泥的实际颗粒群分布。
