启培抗疏力改良膨胀土的自由膨胀率试验研究

Qi Pei CONSOLID Improving Expansive Soil experiment of free swell ratio

膨胀土是一种广范分布的,具有遇水膨胀、失水收缩的特殊性黏土,其特殊性质使其成为困扰工程建设的世界性技术难题。本文用启培抗疏力处理剂在试验室进行膨胀土的自由膨胀率试验研究,试验发现启培抗疏力可有效降低膨胀土的自由膨胀率,在加入2%、5%、15%时,可分别使低、中、高膨胀性膨胀土降到无膨胀性,表明启培抗疏力对于膨胀土的膨胀性抑制作用明显,可用于工程中膨胀土的抗膨胀处理。

Expansive soils are a kind of broad range distribution particularity clay,with water swelling,dehydration contraction,its special nature makes the construction of a world plagued by technical problems.In this article,Qi Pei CONSOLID treatment agent in laboratory studies to test free expansion of expansive soil test found Qi Pei CONSOLID can effectively reduce the free expansion of expansive soils in the incorporation of 2% ,5%, 15% ,they may be to make low,medium and high expansion expansive soil down to no expansion,in- dicating Kai Pei CONSOLID expansive soil to expansion antiexpansion project of expansive soils. significantly inhibition can be used to deal with theantiexpansion project of expansive soils.
