A study of alkali-activated concrete mixes in seawater environments
Mengasini L., (Corresponding) Mavroulidou M., Gunn M.
Topic:
Marine environment and coastal management
This paper assesses the performance in seawater environment of concrete mixes based on alkali-activated (AA) cements; these are proposed as an alternative to Ordinary Portland Cement (OPC) to address environmental footprint of cement production and to find new uses for waste materials. The proposed...Read more

Reducing the environmental impact of construction wastes by their use in the preparation of construction mixtures
(Corresponding) Junak J., Sicakova A.
Topic:
Hazardous waste management
At present, great emphasis is placed on protecting the environment. Civil engineering, mainly cement production, greatly pollutes the surrounding environment. Even the excavation of aggregate, which is one of the basic components of concrete, does not make any extra contribution to the...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
Improved storage and handling of fine recycled concrete aggregates by accelerated carbonation: towards a quantification method
Vogt S., Koeniger L., Brück F., (Corresponding) Weigand H.
Topic:
Construction and demolition waste
The fines fraction generated by crushing of concrete waste for production of recycled concrete aggregates amounts to 40 - 60 mass-%. Technically, fine recycled concrete aggregates (0 - 2 mm, fRCA) may be employed as a sand substitute in new concrete products. This is, however, hampered by the...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
