expansible soils are those which will suffer considerable swelling and volume change when subjected to water. the resulting swelling pressure may cause complete destruction of such light structures as irrigation canal linings, floor slabs, etc. based upon previous investigations, swelling of clayey soils has been blamed for failure of many irrigation canals in iran and in other countries of the...

Soil Erosion is the detachment, transportation and deposition of soil sediment from one place to another. This has led loss lives infrastructure in many parts Nigeria. properties play a role it vulnerability extent erosion. study aims evaluate selected physical as they interact cause erosion area. The was conducted 2012 gully site relation its potential erodibility channel. done by collection v...

Atterberg limits are important index parameters used to classify soils for various engineering applications. Engineering properties of predicted through simple correlations with and thereby the behavior qualitatively assessed. There two popular methods determining liquid limit, plastic limit is commonly determined adopting rolling thread methods. To avoid operator related variations in by conve...

Soil particle density (rs) is not routinely measured and is assumed to range between 2.60 and 2.70Mgm or to be a constant (2.65Mgm) when estimating essential properties such as porosity, and volumetric water and air relations. Values of rs for the same soil may, however, differ significantly from the standard range due to managementinduced changes in soil organic carbon (SOC) concentrations.Weq...

Soil activity is a term generally applied to the ability of a soil to take in and dispose water under changing moisture conditions. It is due to presence of clay minerals with a net negative charge to neutralise which, water is attracted to the mineral surface. The water molecules are incorporated in the clay structure in between the clay plates and with increased water; both the exchangeable c...

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...

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...

Abstract This research aims to evaluate the physical and mechanical characteristics of soil stablized with microbial induced cementation method. The variation by 4%, 6%, 8%, while age variations bacterial culture 2, 4, and, 6 days a curing period 3,7,14 28 days. properties studied in this are as optimum moisture content 32.19%, dry volume weight (γd) 1.36 gr/cm 3 , density 2.63 atterberg limit ...
