Effect of Exposure to Water at Different Temperatures during Curing on the Strength of Cement-Treated Soil
Publication: Geo-Congress 2023
ABSTRACT
This paper presents unconfined compressive strength (UCS) test results of cement-treated soil cured under different curing conditions. During curing in water at different temperatures (21.1°C and 45.0°C), the samples for short-term curing were demolded at different times and then placed into the water again to continue the curing. UCS tests were conducted on all the short-term curing samples after an entire curing time of 28 days. On the other hand, for long-term curing, some samples were demolded at seven days and exposed to the water for further curing, while the other samples were sealed by a plastic mold during the entire curing period without any exposure to the water. The entire curing times for the long-term curing were between 100 and 400 days. The UCS test results showed that for the short-term curing, a sample demolded later and exposed to water for a short period was stronger than the sample exposed to water early. This trend was more evident at a high temperature (45.0°C), but the differences in the strength were small. For the long-term curing, a sample cured in the mold at room temperature (21.1°C) for the entire curing time had a higher UCS than the sample demolded at seven days and exposed to water for further curing, while there was no demolding effect at 45.0°C. The test results implied that a cement-treated soil sample cured in the mold can have a higher strength than a soil-cement column for the wet method of deep mixing that is exposed to materials around the column depending on curing conditions.
