The effect of alkaline activated reservoir sediments used as a binder in concrete on its compressive strength

(Corresponding) Junakova N., Junak J.
Topic: 
Lakes, rivers, estuaries and ecosystem health
Sediment as the product of erosion processes is found in every water body and reduces the storage capacity and the lifetime of water reservoirs. The quantity of sediment which affects downstream areas and also their quality complicate sediment management. Dredged sediments are on the borderline of...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

Gas mixture candidates for SF6 replacement in medium voltage switchgear: Analysis and modeling of the filling episodes

(Corresponding) Espinazo A., Lombraña J., Alonso M., Alonso R., Izcara J., Izagirre J., Pereda-Ayo B.
Topic: 
Energy technologies and sustainability
A more environmentally friendly replacement for SF6 must be found for medium voltage switchgear, as a change in European regulations will come into force soon. The mixing process of alternative binary and ternary gas mixtures is studied, which are made up of the hydrofluoroolefin HFO-1336mzz(E) (...Read more
