The Influence of the Clay's Geotechnical Behaviors with the Fly Ash

Abstract:

In this paper, the different proportion and different time of fly ash soil mixed soil properties， mainly the plastic liquid limit and compressive strength were analyzed. The results showed that soil plasticity index was decreased with the increase of the content of fly ash and the plastic liquid limit decrease with the extension of time. The compressive strength of the three kinds mixing with the different water content was increase following the water content decrease. Moisture content is less than the best water content, compressive strength changes with the water content, water content is greater than the compressive strength of the best when water content with moisture content changes gently. This paper analyses the influence mechanism of the characteristics of the fly ash on soil.
