초록

In the present study, an investigation has been made on the application of cement-bentonite soil mixtures as the countermeasure against leachate produced by buried animal carcasses. For this purpose, the strength characteristics of the cement-bentonite soil mixtures mixed with geotextile and metakaolin. After the mixtures with different contents of the cement (0 %, 10 %), bentonite (0 %, 5 %, 10 %, 15 %, 20 %), and weathered soil (100 %, 95 %, 90 %, 85 %, 80 %) were prepared, metakaolin and geotextile were added with different contents (metakaolin : 0 %, 5 %, 10 %, 15 %, 20 % of the cement weight; geotextile : 0 %, 0.5 %, 1 %, 1.5 %, 2 %). Experimental results suggested that the early strength of the mixture increases due to the pore filling, the hydration acceleration, and the pozzolan reaction when metakaolin of 5~10 % of the cement weight was added. In addition, the compressive strength increase when 0.5~1 % geotextile contents were added, and the above these contents, the rate of strength increase was gradually decreased because of the fibrous tangles.
