[ What is claimed is:] [1.]1. A precast concrete module comprising:a plurality of reinforced concrete ribs defining regions therebetween, wherein at least a first said region is substantially covered with at least a first concrete panel, wherein concrete in said ribs is cast and cured substantially simultaneously with concrete in said panels whereby said panels are coupled to said ribs substantially preventing relative rib movement, said ribs having a rib thickness in a first dimension, said panels having a panel thickness in said first dimension that is less than of said rib thickness, at least said first concrete panel being reinforced with a non-metallic reinforcement material comprising both carbon fiber and glass fiber, wherein said ribs define a maximum extent of said concrete module in said first dimension, and wherein exterior surfaces of said ribs are formed from concrete.
