胶体活性 meaning in English

colloidal activity

In the light of its special property being not easy to gain strength , through mechanics researches on different methods to stabilize this kind of low _ liquid _ limit silty soil as subbase material , evaluated both technically and economically , we have got a cement lime stabilization plan to meet the index requirements for non _ side _ limit strength of compression of subbase of class2 road stipulated in the specification ; by means of improving the workmanship , thickening the loose layer of soil , adding soil on covering weave fabric before compaction , such problems can be solved as very poor compaction , loose surface during compaction , roughness and unevenness , coats of layer and shear damages
本文针对黄河冲积而成的低液限粉土其粘粒含量极低、土的不均匀系数很小、胶体活性差的工程特性,通过采用不同方法稳定该类土作底基层材料的力学性能研究,从技术、经济角度综合评价,得到满足规范抗压强度指标要求的水泥石灰稳定方案。通过对原材料、试验配合比设计、施工、等方面进行优化,从而显著减轻了基层的早期及长期缩裂程度,从而提高了路面的耐久性。
