Are Longer and Heavier Vehicles (LHVs) Beneficial for Society? A Cost Benefit Analysis to Evaluate their Potential Implementation in Spain
(Universidad Politécnica de Madrid, 2014)
In this paper we carry out a thorough review of the current research related to the benefits and costs arising from the implementation of longer and heavier vehicles (LHVs). From this review we concluded that despite the ...
Resistance of blended concrete containing an industrial petrochemical residue to chloride ion penetration and carbonation
(Universidad Nacional de Colombia, 2014)
In this study, the resistance of blended concrete containing catalytic cracking residue (FCC) to chloride ion penetration and carbonation was examined. FCC was added at the levels of 10%, 20%, and 30% as partial replacement ...
Gasification of Biomass in a Fixed Bed Reactor
