Abstract
This paper aims to effectively evaluate the accelerating effect of curing conditions at differ-ent temperatures on the strength development of cement treated soil.The study conducts the uniaxial com-pression tests and thermogravimetric analysis on the cement treated soil samples cured at different temper-atures and investigates the accelerating effect of temperature on strength development.The results indicate that with the increase of curing temperature,the acceleration effect of the strength development of cement treated soil is enhanced.Based on Arrhenius rule,the accelerated intensity development effect of equiva-lent age can be evaluated accurately.With the same equivalent age,the hydration reaction could go at the same speed regardless of the curing temperature.When cured at 70 ℃,the acceleration effects of strength development and hydration reaction are equal to or less than 55 ℃,indicating that there is an upper limit to the temperature of the acceleration effect of strength development.This research results have reference significance for high-temperature curing cement treated soil in engineering practice.关键词
