Determination of the suction compression index, Ch, is necessary for predicting expansive soil heave based on soil suction. The CLOD Test is a convenient laboratory procedure for determining Ch, however it is not widely used. Rather, engineers often rely upon empirical correlations to find Ch. A laboratory investigation was conducted to verify previously established empirical relationships. The...

Tanah ekspansif termasuk dalam jenis tanah bermasalah yang sangat sensitif terhadap perubahan kadar air. Jenis ini menyusut secara signifikan sebagai akibat dari volume pori, menciptakan gaya angkat pada struktur ada dan berpotensi merusaknya. Tujuan penelitian untuk melihat perilaku berada di bawah slab beton, mulai pola pengembangan, tekanan ditimbulkan ketika mengembang kecepatan rambatan al...

Machine traffic and timber skidding significantly affect the soil surface and soil properties. The effects are mostly negative and result in soil erosion, worsening of soil properties and inhibition of the growth of roots and soil organisms. In this study, we evaluated forest soil damage caused by the HSM 805 HD wheeled skidder during timber skidding in selected forest stands in the School Fore...

A number of environmental, agronomic and engineering applications require knowledge the Atterberg limits (liquid limit, LL; plastic PL) plasticity index, PI soils. The tedious costly nature standard experimental methods, as well challenges with measurement repeatability motivated development regressions more sophisticated techniques to estimate from other properties such clay content, cation ex...

Cement is proven increasing the strength of soft clays. Monmorillonite has a high shrinkage. Another hand, Kaolin small Waste material usage for stabilization agent was widely carried out this decade. BAFA (bottom ash fly ash) and POFA (palm oil fuel are rich in Silica Alumina, so they used to substitute cement. The study examined effect Monmorillonite, Kaolin, on clay with Bentonite from 4% 16...

The study of geotechnical index properties soils in Oworoshoki, Kosofe, Lagos State was conducted to characterize and classify the soil samples. Disturbed undisturbed were collected at different shallow depths (1m, 2m 3m) from area laboratory test conducted. includes natural moisture content, atterberg limits (liquid limit plastic limit), particle size distribution, specific gravity, unit weigh...

Correlations between compression index and atterberg limits found in the literature are very important for preliminary estimation. These equations usually interpreted based on R-square parameter classified according to conditions of data (disturbed, undisturbed, remoulded, etc.). Although correlations reliable enough eliminate oedometer tests not yet fully available, these can be useful local c...

The Fall cone liquid limit testing procedure for low plasticity soil mixtures with sand, including the sample preparation and implementation of plastic determination suggestions are covered within this research. A apparatus was used in order to determine limits types, which Casagrande cup thread rolling methods proved inapplicable. Several issues addressed concerning standardized mixture fillin...
