Abstract

The experimental study is to understand the mix ratio of fly ash and GGBS (ground granulated blast-furnace slag) in improving the shrink-swell characteristic of soil. The strength of the soil improved considerably after the addition of these stabilisers. In this study, experiments were conducted to observe the influence of the soil stabilisers in the improvement of the strength of the subgrade in expansive soil regions. This influential study will reveal the percentage of Flyash and GGBS mixture. Then the Standard Proctor Compaction test is used to determine the optimum moisture content required to compact the soil with Flyash and GGBS to attain the maximum dry density. The soil’s California Bearing ratio (CBR) was computed to understand the behaviour of improved soil if used as a subgrade. Hence the existing soil can be used as a subgrade with effective treatment of soil.

膨胀土稳定成分有效处理的实验室评价

本试验旨在了解粉煤灰与矿渣微粉的配合比对改善土壤收缩膨胀特性的作用。添加这些稳定剂后，土壤强度显著提高。在本研究中，通过试验观察了土壤稳定剂对提高膨胀土地区路基强度的影响。这项有影响力的研究将揭示粉煤灰和GGBS混合物的百分比。然后使用标准普氏压实试验来确定用粉煤灰和GGBS压实土壤以达到最大干密度所需的最佳含水量。计算土壤的加州承载比（CBR），以了解改良土壤用作路基时的性能。因此，现有土壤可以作为路基，并对土壤进行有效处理。

期刊介绍： Asia, as a whole region, faces severe stress on water availability, primarily due to high population density. Many regions of the continent face severe problems of water pollution on local as well as regional scale and these have to be tackled with a pan-Asian approach. However, the available literature on the subject is generally based on research done in Europe and North America. Therefore, there is an urgent and strong need for an Asian journal with its focus on the region and wherein the region specific problems are addressed in an intelligent manner. In Asia, besides water, there are several other issues related to environment, such as; global warming and its impact; intense land/use and shifting pattern of agriculture; issues related to fertilizer applications and pesticide residues in soil and water; and solid and liquid waste management particularly in industrial and urban areas. Asia is also a region with intense mining activities whereby serious environmental problems related to land/use, loss of top soil, water pollution and acid mine drainage are faced by various communities. Essentially, Asians are confronted with environmental problems on many fronts. Many pressing issues in the region interlink various aspects of environmental problems faced by population in this densely habited region in the world. Pollution is one such serious issue for many countries since there are many transnational water bodies that spread the pollutants across the entire region. Water, environment and pollution together constitute a three axial problem that all concerned people in the region would like to focus on.
