hollow core pre-cast concrete slabs. primarily used as floor or roof deck systems, hollow core slabs also have applications as pedestrian bridge deck units. hollow core is the product of choice in buildings requiring sound barriers between floors.
accelerated bridge construction using precast bridge elements - duration: bridge deck removal using concrete cutting for demolition support for hollow-core slabs - duration: 1:43.
structural precast. insulated wall panels hollow core slabs precast bridge girders directly support the bridge deck and are more economical than steel girders. the durable, maintenance-free bridge product is prestressed to achieve favorable span-to-depth ratios.

hollow core concrete plank bridges are highly economical and quickly constructed. when compared with the construction of traditional beam and decking bridges, the cost of a hollow core plank bridge not only compares favourably but in addition offers a far more rapid construction time. for example in the case of a regional road, hollow core concrete
this technique is usually found in concrete beams, spandrels, columns, single and double tees, wall panels, segmental bridge units, bulb-tee girders, i-beam girders, flat slabs and hollow-core slabs. during post-tensioning of concrete, the compression is added following the curing process.
hollowcore commercial applications hollowcore commercial applications . massive strength and proven durability. hollowcore gets its strength from pretensioned steel strands that are embedded in high strength concrete. continuous voids in the planks reduce their overall weight and help keep building costs in check. bridge deck units
