A system for producig crack-free prestressed concrete by avoiding the temperature differentials due to escaping heat of hydration and sunshine is discussed. A description of girder production is followed by a report on slab production. The requirement of the strictest possible homogeneity of girders and slab is covered, and the structural, organizational, and economic advantages of the system are enumerated. If applied according to specifications, this system produces crackless prestressed concrete of such density and appearance that almost no maintenance is required. The system also yields considerable savings in material, labor, and overhead.
