水泥加固类路面基层填料的浸水强度

在浸水条件下,对不同水泥占比和不同养生时间的加固土进行单轴抗压强度试验,试验结果表明:低液限黏土经固化剂加固后的最佳的含水率灵敏度比原土样有所减小,且随着水泥占比的增加而下降;养生时间一定的情况下,加固土的抗压强度随着水泥占比的增加而增大,水泥占比的增加对后期强度的影响较前期强度更显著;抗压强度随着养生时间增加而增大,...

Study on Flooding Strength of Cement Reinforced Road Base Filler

Uniaxial compressive strength test was carried out under the condition of immersion in water to improve the cement soil under different influencing factors. The test results show that the optimum moisture content sensitivity is lower than that of the original soil sample. The compressive strength of reinforced soil increases with the increase of the proportion of cement, and decreases with the increase of the proportion of cement. The increase of the proportion of cement has more significant influence on the strength in later stage. The compressive strength increased with the increase of curing time, and the growth rate gradually slowed down with the increase of curing time. The hydration reaction of cement was basically completed at 28d. The water resistance coefficient increases at each age. With the increase of the proportion of cement, the water stability of the reinforced soil is enhanced, but the water resistance coefficient under various conditions is less than 0.75.
