Cure Time Effect on Compressibility Characteristics of Expansive Soils Treated with Eco-Cement
The objective of this paper is to investigate the influence of curing time on expansive soil as a construction material when treated with eco-cement stabilizer, as partly substituting the Portland cement. Standard consolidation samples were prepared from treated soils with 10 % cement (5% eco-cement and 5% Portland cement), reported to the dry unit weight of soil, and cured for 1, 7 and 14 days. After this period the soil samples were then socked in water and standard consolidation tests were performed on them. The compressibility characteristics, for the improved soil with 10% cement, Eoed, mv and Cv have shown a significant improvement during the first 7 days. After 7 days curing time the variation of compressibility characteristics is less pronounced.
