Abstract

Through a laboratory experiment of improving the silt in Huangdun Lake flood detention area, the reinforcement effect of two different soil conditioners-cement and fly ash on silt of detention area were researched. The study found that soil conditioners can effectively improve the soil compaction and gentle the compaction curves in the peak range, which was beneficial to the control of water content in the concrete construction. Compaction degree had different effects on the compressive strength of this two kinds of improved filler soil. With the increase of compaction degree, the compressive strength firstly showed a different proportion of growth, and began to be steady or reduce weakly after increasing to a certain value. The best compaction degree of the two kinds of improved soil was both between 95%~97%, and the cement fly ash stabilized soil had best ratio in strength, namely with the increase of fly ash content , the compressive strength firstly increased and then decreased, which means the fly ash had the beat optimum mix content.
