Innovative methods of ground improvement for problematic transport earthwork materials
(Corresponding) Mavroulidou M., Safdar M., Gunn M., Gray C., Payne I., Garelick J., Purchase D.
Topic:
Environmental management and policies
The paper focuses on emerging (bio-) chemical techniques used to improve engineering properties of two problematic earthwork materials of the UK rail network to address transport earthwork infrastructure resilience in view of climate change. Studied techniques include novel cementing agents (e.g...Read more
A comparative study of alkali activated slag cement concretes with carbonate and silicate activators.
Sanam I., (Corresponding) Mavroulidou M.
Topic:
Environmental management and policies
Alkali-activated cements are increasingly gaining interest as viable alternatives to Portland cement, because they are considerably reducing CO2 emissions compared to traditional Portland cements while maintaining or exceeding performance requirements commonly specified for construction...Read more
A comparative assessment of alkali-activated stabilisers including waste materials, for the treatment of swelling-shrinking soils
(Corresponding) Mavroulidou M., Gray C., Gunn M.
Topic:
Solid waste management
Swelling-shrinking soils (also known as expansive soils) experience very considerable volume changes upon changes in moisture content, thus causing major damages to lightweight structures, pavements, slopes and utilities. To counteract this problem chemical stabilisation of this type of soil with...Read more

A study of the properties of alkali activated cement concrete with potassium carbonate activator.
(Corresponding) Mavroulidou M.
Topic:
Net Zero emission transition
Alkali-activated cements (AAC) have recently attracted the vivid interest of the civil engineering industry as promising innovative alternatives to Portland Cement (PC) which is responsible for 8% of anthropogenic CO2 emissions. In this context, this paper studies concrete produced using potassium...Read more
Use of food waste as culture media in biocementation for ground improvement applications
Mwandira W., (Corresponding) Mavroulidou M., Gunn M., Gray C.
Topic:
CIRCULAR ECONOMY AND BIOECONOMY
The paper investigates the use of mixed fruit and vegetable (FV) waste to extract liquid to grow bacteria. The bacteria will be used to induce biocementation of soils and two metabolic pathways are examined. These are the ureolytic pathway and the carbonic anhydrase pathway (which absorbs CO2)...Read more
