Stabilization Potential of Openly Burnt Coconut Waste AshesonA-7-5 Soi

Soil materials are a vital element in all civil engineering designs hence the first step in any geotechnical engineering project is to identify and describe the soil condition if not suitable, disposal or stabilization of the soil should be carried out . In lieu of these, this research was carried out to study the effects of coconut waste ash (CWA) derived from open uncontrolled burning on lime stabilized A-7-5 soil for road construction. Natural soil was collected from a borrow pit location ...

Pultruded FRP-Concrete hybrid beams: characterization of shear connection behavior through static push-out tests

This paper discusses the recent investigation into the composite action of pultruded Fibre Reinforced Polymer (FRP) and concrete hybrid systems, under static push-out tests. The study sought to experimentally determine the characteristic load-slip behaviour of the FRP-concrete composites under varying shear stud arrangements and failures modes associated with the variations and the push-out load capacity. For the initial tests, three composite test spe...

STABILIZATION OF SILTY CLAY SOIL USING CEMENT AND SAW DUST ASH samson et al

ABSTRACT Soils containing large quantities of clay and silt are the most burdensome to the engineer. These soils exhibit marked changes in volume with changes in water content and consequently affect the function of any layer lain upon it due to its shrink and up heave behavior when used as a subgrade or a layer built of it. The test assesses the geotechnical characteristics of silty clay soil in order to increase the shear strength and decrease the compressibility of the soil, so t...

EFFECTIVENESS OF PORTSMOUTH HIGHWAYS PRIVATE FINANCE INITIATIVES (PFI) SCHEME

Since the inception of the Private Finance Initiatives (PFI) in the United Kingdom, Government are increasingly adopting it as a means of proving infrastructure to the public neglecting the traditional procurement methods which relies completely on the public finance. Private Finance Initiative (PFI) is a method of contract procurement where the private organisation provides an infrastructure, finances, operates and maintains the infrastructure. This is done by transferring the risks involved...
