Research evaluates strength estimation method for cement-treated soils with varying cement content, suggesting effective prediction under high temperatures.
Key Points
This research investigates the applicability of a strength estimation method based on curing history for cement-treated soils with different cement content.
Conducted uniaxial compression tests under controlled temperatures of 20-55°C.
Performed thermal analysis to assess hydration reactions.
Examined the impact of equivalent age on strength enhancement and reaction progress.
The strength improvement characteristics can be evaluated using equivalent age regardless of cement content.
The apparent activation energy decreases with higher cement content, indicating enhanced strength response.
The estimation accuracy for strengths at ages 28-112 days is high under lower temperature combinations for all cement amounts.
