EFFECTS OF ORDINARY PORTLAND CEMENT ON THE SOIL-WATER CHARACTERISTICS CURVE OF LATERITIC SOIL

Suranaree Journal of Science and Technology, 2023
The lateritic soil, abundant in tropical and sub-tropical countries, is a common construction material used for various purposes, such as constructing transportation infrastructures, landfills, and other earthworks. The residual lateritic soil is usually

Strength and structure of laterites and lateritic soils

Engineering Geology, 1973
Abstract Ten soils from Puerto Rico representing various states of weathering were subjected to engineering index tests, strength and density measurement, mineralogic analyses, and scanning electron microscopy. Engineering classification systems used for temperate soils tend to underestimate the engineering behavior of these undisturbed lateritic ...

Laterite and lateritic soils in Sierra Leone

The Journal of Agricultural Science, 1927
(1) The formation of laterite and lateritic soils in Sierra Leone has been studied and the mode of formation and the composition of these soils is described.(2) It is suggested that since the clay fraction is regarded as the most important fraction in determining the reactions of a soil the classification of laterite and lateritic soils should be based

Laterite and lateritic soil in Sierra Leone, II

The Journal of Agricultural Science, 1930
1. A study has been made of the formation of lateritic soils in Sierra Leone and the composition is given of some of the intermediate and final products formed.2. The detrital soils in Sierra Leone appear on the whole to contain a higher proportion of alumina to silica than the residual soils.3.

Adsorption of carbofuran on lateritic soils

Journal of Hazardous Materials, 1998
Adsorption of carbofuran on the four selected lateritic soils is studied using batch experiments. Accordingly, the key influencing factors of carbofuran adsorption are determined. The adsorption isotherms on the lateritic soils correspond well with the Freundlich isotherm.

Effect of compaction water content and stress ratio on permanent deformation of a subgrade lateritic soil

, 2021
Permanent deformation is a potential distress that affects the functional characteristics of pavement. Subgrade soil might contribute to different levels of permanent deformation depending on traffic intensity.

Recent Laterites and Lateritic Soils

Soviet Geography, 1961
AbstractThe author notes that the large literature on laterites and lateritic soils is concerned mainly with regional description and the physical-chemical processes of soil formation. No attempt is made to analyze the geographical-genetic conditions under which such soils are formed.
