以前的论文 1,2 中研究的飞灰和其他材料的火山灰活性已通过两种化学方法确定，该方法基于估算火山灰与石灰反应时产生的酸溶材料的量。从这些结果得出的关于决定灰烬活性的因素的相对重要性的结论与先前基于粉煤灰砂浆的抗碎强度的结论一致，如已经提出的。砂浆中发生的化学反应量与其产生的强度之间存在密切关系，但短期化学评估表明与长期抗碎强度无关。结论是，化学方法对于预测现场迫击炮的长期强度不太可能有任何实用价值。
The pozzolanic activities of the fly ashes and other materials examined in previous papers1,2 have been determined by two chemical methods based on estimating the amount of acid-soluble material that is produced when a pozzolan reacts with lime. The conclusions reached from these results, on the relative importance of the factors that determine the activity of an ash, agree with those previously based on the crushing strengths of fly ash mortars, as already presented. There was a close relation between the amount of chemical reaction taking place in a mortar and the strength it developed, but short-term chemical assessments showed no relation to long-term crushing strengths. It was concluded that chemical methods were unlikely to have any practical value for predicting the long-term strength of a mortar in the field.
