文章通过对水泥土加固机理和水泥水化、硬化原理的分析,以及对粉煤灰特性的研究基础上,发现影响水泥土强度的主要因素是有机质含量,其次是水泥掺入比,再次之是粉煤灰掺入量。有机质含量越高,水泥土强度越低;粉煤灰对高有机质软土具有很好的加固效果,但强度并非是随着粉煤灰掺量的增加而不断增长,当粉煤灰掺量超过12%时,强度不但不增加反而降低,而且降低的幅度很大。
Based on the analysis of cement-soil reinforcement mechanism, cement hydration and hardening principle, and the research on fly ash properties, the main factors affecting the strength of cement-soil are found to be organic matter content, followed by cement incorporation ratio, and again Fly ash incorporation. The higher the content of organic matter, the lower the strength of cement soil; fly ash on the high organic matter soft soil has a good reinforcement effect, but the intensity is not with the increase of fly ash content increases, when the fly ash content exceeds 12%, the strength not only does not increase, but lower, and reduce the magnitude.
