Duct covers made from carbon-reinforced concrete

Carbon-reinforced concrete is suitable for a number of applications, including façades, walls, columns, beams, floor slabs, and modular buildings, as well as for repairing and upgrading existing structures. A precast production environment appears to be particularly beneficial for manufacturing carbon-reinforced concrete components; it is thus the predominantly used method at this stage. One of the reasons for this trend relates to the uniform, optimized conditions prevailing at the precast plant, which enable the production of more slender components at a lower cost than, for instance, with...
