Effects of lime on improving swelling characteristics of the soilweathered from acid magmatic rock in the central highlands of Vietnam
03/01/2024This paper presents the research results on the effects of lime on improving expansive characteristics and shear strength of soils weathered from acid igneous rocks in the Central Highlands of Vietnam. Swell tests were implemented for the mixtures of soil and lime with variety of lime contents of 1%, 3% and 5% over periods of 0, 7, 14 and 30 days. Direct shear tests on soil-lime mixtures were also carried out to analyze the effects of lime on shear resistance characteristics of those samples. By adding 5% of lime, the swelling degree of the soil shows a significant decrease, from 19% to 4%. In addition, the shear strength of the soil also has a noticeable improvement.
