High-Performance Concretes-Behavior of Fresh Concrete
(Universitatea "Dunarea de Jos" din Galaţi, 2003)
Most of the research in High-Performance Concretes (HPC) since the
publication of the State-of-the-Art Report in 1990 has concentrated on
increasing basic knowledge regarding HPC performance and properties
rather than ...
Hydraulic Plant with Energy Inertia Recuperator for Single Bucket Excavator
(Universitatea "Dunărea de Jos" din Galați, 2004)
This paper analyse the driving solutions for hydraulic single bucket
excavators, by the point of view of the energy consumptionon the
technological working cycle. It is presented a solution of accumulation
and re-circulate ...
