粉煤灰与生石灰加固软土的力学特性试验研究

本文进行了无水泥状态下粉煤灰与生石灰加固土的无侧限抗压强度试验,相同比例的干土、水,再和不同比例的生石灰与粉煤灰掺合,人工拌和均匀后,装入模具,震动,养护,最后测定了不同龄期的试块的无侧限抗压强度;实验研究表明当同龄期时,试块的抗压强度会随着粉煤灰掺量的增加、生石灰的掺量的减少而变小。当相同粉煤灰和生石灰掺量,试块的抗压强度随着龄期增加有较大的增长。

The author of the cement state of fly ash and lime stabilized soil unconfined compressive strength test, the same proportion of dry soil, water, and different proportions of lime and fly ash blended artificial mixing evenly, into a mold, vibration, maintenance, and finally determined instars test block unconfined compressive strength; （ash content = fly ash ＋ lime） experimental studies have shown that when the age of the test block compressive strength With the increase of the amount of fly ash, lime dosage reduction becomes smaller. When the same fly ash and lime dosage, the compressive strength of the test block to increase with the age of a larger growth.
