Due to its significant deficiencies such as low permeability, bearing and shear strength, excessive compressibility, soft soil is one of the most problematic types in civil engineering stabilization can be considered a suitable technique for pavements. This study investigates use ground granulated blast slag (GGBS) cement kiln dust (CKD) stabilizers soil. Thus, this involves two optimization st...

The study evaluated the effect of four treatment compositions on plasticity tropical red soil (Lateritic soil) admixed with Bacillus coagulans (B. coagulans). Samples for Atterberg limits test were prepared using compositional variables. They include 25% B. suspension and 75% cementation reagent, (25%B /75%C); 50% reagent (50% B /50%C); (75%B /25% C) above three being in equivalent volumes corr...

Abstract This research paper is concerned with studying and evaluating the geoengineering characteristics potential risks of area under study a view to safe urban expansion using GIS techniques. Different geotechnical laboratory tests such Atterberg limits, free swelling test, swell pressure tests, chemical analysis, unconfined compressive strength (UCS) rock quality designation (RQD) were perf...

Abstract Expansive subgrade soil needs to be re-engineered enhance the load-bearing capacity as it lacks sustain traffic and pavement load. Although various chemical modification techniques have proven effective for stabilization, they are expensive unsustainable. Coronus aggregate material is an uplifted coralline deposit abundantly available in Pacific. The current study focuses on strength b...

‎We firstly prove the completeness of the category of crossed modules in a modified category of interest‎. ‎Afterwards‎, ‎we define pullback crossed modules and pullback cat objects that are both obtained by pullback diagrams with extra structures on certain arrows‎. ‎These constructions unify many corresponding results for the cases of groups‎, ‎commutative algebras and can also be adapted to ...

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...

Most of Iraqi soil is classified as Quaternary deposits, especially in the Mesopotamian plain and tributaries of the River Tigris. Soil varies from north to south of Iraq. These differences in soil affected the process to select the suitable type of foundation. This research is to study the effect of bearing capacity on shallow foundations in different regions of Iraq. Seventy nine samples were...

There is a continuous attempt at seeking different, economical and environmental-friendly means of improving the strength soils. This work therefore studied effects shredded plastic waste (SPW) on selected To achieve aim study, lateritic soil samples were collected from two identified active borrow pits in Ile-Ife. Following standard procedures, following tests conducted soils their natural sta...
