Self-Compacting Concrete (SCC)
Since self-compacting concrete (SCC) emerged on the scene in the late 1980ies in Japan it has been the subject to numerous investigations in order to adapt it to modern concrete production. At the same time the producers of additives have developed more and more sophisticated plasticizers and stabilisers tailor-made for the precast and the ready-mix industry. SCC has a long line of advantages. From the contractors point of view costly labour operations are avoided improving the efficiency of the building site. Furthermore, the concrete workers avoid poker vibration which is a huge benefit for their working environment. When vibration is omitted from casting operations the workers experience a less strenuous work with significantly less noise and vibration exposure. It should also be noted that SCC is believed
to increase the durability relatively to vibrated concrete. This
is due to the lack of damage to the internal structure, which is
normally associated with vibration. © Copyright 2003 by ECOserve |
