Effect of different agents on the stabilisation of a clay soil contaminated with glycerol
Effect of cement, Ground Granulated Blast Furnace Slag (GGBS), GGBS:magnesia (MgO) and GGBS:MgO:cement were studied as agents on stabilisation of a clay soil contaminated with glycerol solution. The contaminated soil was mixed with 5, 10 and 15% of the above agents. Atterberg limits and compaction tests were conducted on these mixtures. Additionally, strength and durability tests were performed on prepared samples at different curing times. The strength of soil contaminated with 4, 8, and 12% glycerol was reduced by 23.5, 30.1, and 36.5%, respectively, compared to the natural soil. By adding 5% cement to the soil contaminated with 4% glycerol, its strength after 7, 14, and 28 days of curing time was increased to 1581, 1984.5, and 2343.4 kPa, respectively. All the selected agents increased the strength of the contaminated soil and its increase was dependent on the percentage of the agent and curing time. It was revealed that GGBS:MgO:cement was more effective in increasing the strength than the other used agents. Durability tests also showed that the weight loss of the samples at different conditions was less than 10%. SEM results showed that the increase in strength of the soil results from the interaction between soil and agent.
