The structure and morphology of nonmaterial formed by colloidal synthesis represent a subject of interest as it is a factor deciding the physicochemical properties and biological applications of nanostructures. Among various nanoparticles, gold can develop fractal assembled patterns. Herein, we report a nano-aggregate of a thiol-on-gold self-assembled structure and the influence of β-cyclodextr...

Abstract Steel slag aggregates can be utilized as unbound materials for road bases or fine/coarse in asphalt/cement paving concrete. However, the availability of free lime (f-CaO) is detrimental to volumetric stability, affecting strength durability resulting products incorporating steel aggregates. This paper investigates potential expansion fine and coarse compacted at different compaction de...

In the UK, at present, the majority of aggregate materials, for all construction applications, are obtained from primary resources such as crushed rock and sand and gravel. Material extraction results in many adverse environmental impacts and utilisation consumes a finite natural resource. In the UK we also produce large quantities of waste and by-product materials, from industrial and domestic...

The policy of driving organization such as Highways Agency is towards the use of performance related specifications. This policy and adoption of European wide aggregate standards on the one hand, and sustainable construction pressures on the other, all strongly emphasize on further need for more developments to specifications and performance assessment methodologies inst...

The diminishing quantity of natural resources has resulted in a search for alternative materials. Reusing industrial by-products, such as steel slag, provides opportunities sustainable highway construction practices due to the valuable space they occupy and potential environmental impacts when are stockpiled. In this paper, mechanical suitability slag an unbound aggregate is investigated, its p...
