Abstract This study was to evaluate the engineering properties of cement stabilized expansive clay soils. considered an experimental program determine Atterberg limits, free swell index, compaction characteristics, California Bearing Ratio (CBR), and mixtures. The collected soils were using 10, 12, 14, 16 % by weight. laboratory results showed that have low shear strength high swelling potentia...

The undrained shear strength is a paramount parameter in determining the consistency and ultimate bearing capacity of clay layer. This resistance can be determined by in-situ tests, such as field vane test or laboratory including portable test, triaxial, simple compression penetrometer (i.e. Swedish cone). However, cone are most commonly used geotechnical experts. In this paper, relationships b...

The more coal production is produced, the waste coming from combustion process which leads to environmental pollution. Waste burning in form of fly ash can be used as a mixture subgrade stability highway construction. purpose this study determine characteristic value each combination ash, Liang Anggang sand and cement layer materials. test objects consist 10 combinations cement. Some tests were...

This experimental study investigated the effect of plastic waste powder on strength and swelling behavior tuff bentonite soils treated by cement since is highly compressible does not absorb much water. aimed to improve used in construction adding various ratios (5, 10, 20, 25%) a low content (2.5%). Atterberg limit, consolidation, loading-unloading tests were performed determine optimal composi...

Diatomite is a powdering mineral mainly composed of diatom microfossils present in marine and lacustrine soils, which influences their physical mechanical properties. Although many articles have been found the literature concerning influence diatomite overall behavior natural few research efforts carried out to evaluate microfossil species on shear resistance. Therefore, this research, content ...

This paper shows the use of dimension stone waste in manufacture soil-cement bricks. Initially, a sample soil was analyzed for mineralogical composition, particle size distribution (classifying it proportion silt, sand, and clay), physical performance by plasticity (Atterberg limits specified standard NBR 7180). A series soil/waste/cement mixtures were prepared with contents up to 90% wt.% wast...

Waste management is a complex and detailed process that involves evaluation of certain important factors, such as a geological, geotechnical, hydrological, hydrogeological, climate, urban management, environmental, along with social, cultural, and psychological parameters. Unfortunately, in Iran, there is minimal evaluation of initial parameters and in some cases even don’t exist. The purpose o...

One of the most important materials in building industry is earth brick. The current work focuses on evaluation Maroua soils and their potential usage manufacturing Compressed blocks (CEB). Four sites (Frolina, Goubeou, Mambang, Djoulgouf) were chosen to conduct this study. sample was collected at each location. Physico-chemical mineralogical characteristics obtained by using particle size, Att...

Fine-grained, more or less cohesive carbonate materials are extremely widespread in terms of surface area and are, therefore, commonly used as materials to construct impermeable cores for dams. However, it has not been adequately documented whether the carbonate content in fine-grained soils significantly affects their engineering behaviour. The present study shows that the carbonate content su...

Using low permeability soils in landfill liners is a guaranteed leachate control and prevents leakage which causes environmental pollution. In this matter, the application of new technologies such as nano provides more capable filters that are used for reducing pollutants modifying geotechnical properties liners. The presented study attempted to conduct experimental research on nanoclay–nanofib...
