Hollowcore slabs are precast prestressed concrete elements extensively used for floor, roof slabs and wall panels. The success of this precast product is owing to the combination of high efficiency of design, automated production technology resulting in remarkable low price, versatility in the selection of unit depth and capacity, in addition to its ready-to-paint smooth soffit as well as its high quality and durability.
The automated manufacturing process uses a combination of dry mix concrete and shear compaction, which considerably reduces the consumption of water and concrete if compared to conventional process. This key sustainable advantage is recognized by governmental authorities (such as Dubai Municipality, Abu Dhabi Municipality, and Estidama / Leed).Hollowcore is manufactured using long line extruders which form continuous cores running through the slabs. The primary purpose of these cores is to decrease by 40% to 50% the weight of the slabs, which leads to significant savings in the rest of the members of the building construction. They are also used as pre-existing conduits to place electrical cables and pipes, thus reducing even further the overall construction time.
