Standardisering av brokonstruksjoner for nasjonale hovedveier
Masteroppgave bygg BYG500 - Universitetet i Agder 2017 Standardization is currently not being utilized much in the Norwegian road building industry compared to the rest of the construction industry and road construction abroad. To harvest the potential benefits, it is interesting to determine how to increase the use of standardization in road building. The aim of this master’s thesis is to determine how to make use of standardized concrete bridges for the construction of new national highways. To investigate this, the thesis has established knowledge on today’s situation and found dominant obstacles towards a more widespread use of standardized bridge solutions. The Norwegian Public Roads A…
From Waste to Resource – Utilising Residue from Ready-Made Concrete as New Aggregate
Abstract A new admixture is available, to reduce the sludge produced from the cleansing of production and transportation equipment in the fresh concrete industry. The result is agglomerations of hardening concrete, that might be utilised for aggregate. Utilisation depends on adequate properties. This paper reports from investigations on the physical and mechanical properties of the aggregate and discussions on the performance relative to natural and recycled aggregates and towards requirements for utilisation. The findings indicate substantial potential for utilisation, supporting the reduction of waste for deposit and development of the concrete industry towards a circular economy.
