| Summary: | A reinforced concrete hollow core one-way slab is one of the types of slabs used widely around the world in <a id="_GPLITA_0" style="border: none !important; display: inline-block !important; text-indent: 0px !important; float: none !important; font-weight: bold !important; height: auto !important; margin: 0px !important; min-height: 0px !important; min-width: 0px !important; padding: 0px !important; text-transform: uppercase !important; text-decoration: underline !important; vertical-align: baseline !important; width: auto !important; background: transparent !important;" title="Click to Continue > by UltraCoupon" href="#">residential<img style="border: none !important; display: inline-block !important; text-indent: 0px !important; float: none !important; font-weight: bold !important; height: 10px !important; margin: 0px 0px 0px 3px !important; min-height: 0px !important; min-width: 0px !important; padding: 0px !important; text-transform: uppercase !important; text-decoration: underline !important; vertical-align: super !important; width: 10px !important; background: transparent !important;" src="http://cdncache-a.akamaihd.net/items/it/img/arrow-10x10.png" alt="" /></a> and industrial buildings to take advantage of them Economic and thermal insulation as well as to reduce the self-weight of the construction.
