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

Declassification of drilling waste from oil & gas exploitation through end-of-waste criteria to be used as construction materials
Kazamias G., (Corresponding) Zorpas A.
Topic:
Hazardous waste management
All activities related to Oil & Gas Exploration, Production, Storage and Transportation involve waste generation associated to potential risk to environment. Waste types are related to Exploration and Producing (E&P) activities. These activities are: Drilling operations, Production...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
