About this event

The emergence of a wide range of soil and aggregate cementitious binders in pursuance of sustainability and/or the mitigation of the effects of climate change has somewhat clouded the understanding of classical soil and aggregate binding mechanisms.

In this regard, lime has been the traditional binder for soils, with or without involving the participation of Portland cement. The performance of lime has been boosted by the emergent use of various geo-polymer binding approaches that have looked at supplementary and/or complimentary cementation capability. The central role played by lime has therefore been somewhat eroded by the emergence of these new approaches.

It is however critical that there remains a sound understanding of the original soil stabilisation mechanism among geotechnical engineers, while at the same time embracing the emergent methods. This is the best way for achieving optimal and superior performance never before achievable using lime alone.

This lecture will explore the mechanisms involved in classical soil stabilisation using lime, during which the speaker will use various cases studies to highlight more recent advances in the topic.

John Kinuthia

Prof. John Kinuthia is a professor of Civil Engineering at the University of South Wales (UK). Research interests include sustainable development of infrastructure. Research highlights include a prestigious Royal Society award for innovation in soil stabilization, and for this he was awarded the Brian Mercer award for innovation by the Royal Society in 2003. He is also an innovator in a registered patent on novel cement utilizing Wastepaper Ash and Blastfurnace Slag.

Currently, Prof Kinuthia is head of the Centre for Engineering Research & Environmental Applications (CERA) at the School of Engineering at USW. The centre maintains accreditation by the United Kingdom Accreditation Service (UKAS) for testing of materials. It is also an Accredited Notified Body under the EU Construction Products Regulation, for testing steel, concrete, masonry and related products. The centre undertakes a wide range of consultancies in construction and materials-related problem diagnosis and analysis, R & D, regeneration, and in civil engineering project design.
