The FCS is a simple saw model for the purpose of cutting fresh slabs lengthwise to non-standard widths for slabs smaller than those produced in the slipformer mould. The saw blade is electrically driven. To save costs a used diamond saw blade (Ø 1100 or 1300) can also be used. The machine is manually operated by pushing it forward on the bed rails and is fitted with a loose power cable. 1.2 .

Therefore, slabs in the vicinity of the beams act as flanges for the beam. Interior beams have a flange on both sides, which are called T-beams. Edge beams have a flange on one side only, and referred to as L-beams as shown in Figure 8. Isolated T-beams, which are produced as precast concrete elements, are used in concrete construction.

Prestressed Concrete - an overview | ScienceDirect Topics

Prestressed concrete is a system devised to provide sufficient precompression in the concrete beam by tensioned steel wires, cables, or rods that under working conditions the concrete has no tensile stresses or the tensile stresses are so low that no visible cracking occurs. Figure 14 illustrates the principle.
