粉煤灰加固软土地基的室内配方试验研究

Experimental study of formula indoor of fly ash improving soft foundation

粉煤灰是一种强度较高的工业废弃物,可用来加固软土地基。本文进行了粉煤灰加固土的室内配方试验,分别将生石灰或水泥与粉煤灰按照不同的比例干拌均匀后,再与不同含水量的软土人工拌和均匀,测定了4个龄期的无侧限抗压强度,并进一步分析了其加固机理,旨在为其进一步的研究和工程应用提供参考。

Fly ash is the instruction waste material of higher strength, which can be used to improve soft foundation. The formula experiments indoor of fly ash improving soft foundation were done in the paper. According to the different proportion of plaster stone or cement to fly ash, the samples mixed with soft soil of different water content evenly. Then unconfined compression strength of the samples at four different times were tested and analyzed The improvement mechanism was studied further more. The results we...
