The effect of glycerol on compressional strength of soil and soil - cement mixture

Glycerol is a hydrocarbon compound and is considered an environmental organic pollutant. This paper presents the effect of different percentages of glycerol on the strength of soil and soil-cement mixtures. Compressive strength experiments were conducted on natural soil and soil-cement (with %3 and %6 cement) samples contaminated with different percentages (%3, %6 and %9) of glycerol. Results indicated that compressive strength of soil samples prepared with different percentages of glycerol decrease compare to natural soil while increasing compressive strength of soil-cement mixtures at low percentages (%3) of glycerol. Furthermore using higher percentages of glycerol (%6 and %9) caused decrease in the compressive strength for soil-cement mixtures
