摘要

粉状燃料灰(PFA)的施用量为8.3%(重量比)，通过犁耕结合到严重压实的矿渣中，在一年的时间内显著降低了堆积密度。第二次改良处理为4.8% PFA，第三次单独耕作处理在4个月后都降低了容重，但到12个月时，与未处理的对照相比，容重没有统计学上的显著差异。

The bulk density amelioration of minespoil with pulverised fuel ash

Pulverised fuel ash (PFA) applied at an application rate of 8.3% by weight, incorporated by ploughing to a badly compacted minespoil was shown to reduce bulk density significantly over a one year period. A second ameliorative treatment with 4.8% PFA, and a third treatment with ploughing alone both reduced bulk density after four months, but by twelve months displayed no statistically significant differences in bulk density compared to an untreated control.
