Monolithic Concrete Arches

These arches are constructed for roofing of buildings, bridges and culverts. Monolithic concrete arches are constructed from cast-in-situ concrete, either plain or reinforced, depending upon the span and magnitude of loading. These arches are quite appropriate for larger span. The arch thickness is 15 cm for arches up to 3 m span. Formwork is used for casting the arch, and is erased only while the concrete has sufficiently gained and hardened strength. The curing is complete for 2 to 4 weeks.
