−	The hollow core ~~[https://coolcivilengineering.com/~~ concrete] slab has tubular voids that run the entire length of the slab, typically with a diameter equal to 2/3-3/4 of the slab's thickness, which decreases the weight of the slab, as well as the amount of concrete required. They can also function as service ducts. This type of slab is generally reinforced with longitudinal rebar and can achieve long spans, making it suitable for office buildings, multi-story car parks, and so on.	+	The hollow core concrete slab has tubular voids that run the entire length of the slab, typically with a diameter equal to 2/3-3/4 of the slab's thickness, which decreases the weight of the slab, as well as the amount of concrete required.
