粉煤灰水泥土强度增长机理研究及其试验验证

Study on fly-ash-cemented-soil stress development mechanism and its test verification

分析粉煤灰—水泥系统在土骨架中水化反应,研究粉煤灰—水泥土强度增长机理,通过粉煤灰—水泥土室内试验验证所得出的机理,得出其强度受晶体生长控制的结论。

To study the stress development mechanism of fly-ash-cemented-soil,its hydration reactions of fly-ash-cement system’s hydration process in soil frame are analyzed. To test the mechanism,plenty of indoors experiments of fly-ash-cemented-soil are researched and developed. Through these test,the stress development mechanism of fly-ash-cemented-soil is verified,and get the conclusion that the stress of fly-ash-cemented-soil is controlled by crystal growth process.
