历城段一九五一年建坝时,剩余的浆灰都埋在了坑子里,直至今年都以为不能用了,但挖开一看,还是雪白鲜亮的灰浆,并且很好用。查其原因是:在整理集中这些灰浆时,曾在池上面盖上了0.50公尺厚的砂土,并经水浸润,又加该地很凹每年雨水流进,一直未有干固。据有经验的同志谈,白灰如浆后封好,只要干不了能十年下减低质量。
In 1951, when the dam was built, the rest of the ash was buried in the pit until this year it was thought that it could not be used. However, when it was dug up for a look, it was still a bright white mortar and was very good for use. The reason for this is as follows: During the consolidation of these mortars, the pond was covered with 0.50-meter-thick sand and infiltrated by water. In addition, there was a very concave annual inflow of rain water and there was no dry solid. According to experienced comrades, the ashes are sealed as they are, and as long as they can not be cured, the quality can be reduced over the next 10 years.
