Abstract: Unsaturated clays are subject to osmotic suction gradients in geoenvironmental engineering applications and it therefore becomes important to understand the effect of these chemical concentration gradients on soil-water ...

Abstract: Phosphogypsum is added to building materials to accelerate fly ash pozzolanic reaction and contributes to early strength development of concrete. The release of unacceptable fluoride levels by phoshogypsum on contact with ...

Abstract: Lime–fly ash reactions play a key role in improving the mechanical strength and tailoring the permeability characteristics of compacted fly ash. Activation of fly ash–lime pozzolanic reactions should accelerate the rate ...

Abstract: This paper examines the influence of variations in matric suction on the collapse behavior of compacted Bangalore clay soil. The ASTM filter paper method measured the matric suctions of the compacted soil specimens. The ...

Abstract: Bentonite clay is identified as potential buffer in deep geological repositories (DGR) that store high level radioactive wastes (HLW) as the expansive clay satisfies the expected mechanical and physicochemical functions ...

Abstract: To reduce carbon dioxide (CO2) emissions from the use of cement and lime in civil engineering applications, microbially induced calcite precipitation (MICP) is one of the sustainable technologies being explored. MICP ...

Abstract: This study reports the influence of physico-chemical factors on the swell/collapse characteristics of laboratory-prepared dry silty clay specimens. Also, a comparison of the physico-chemical behavior of dry and saturated ...

Abstract: Geopolymers are an alternative binder to portland cement in the manufacture of mortars and concrete, as its three-dimensional aluminosilicate network imparts excellent mechanical properties. Use of geopolymers in place of ...

Abstract: Soil and water pollution by chromium is a major environmental concern. Although existence of chromium in the

Abstract: Lime stabilization prevails to be the most widely adopted in situ stabilization method for controlling the swell-shrink potentials of expansive soils despite construction difficulties and its ineffectiveness in certain ...
