Reinforced Concrete concrete &The number of pieces, size, length and bending details of the reinforcement in each slab SLEEVE—A tube which encloses a bar, dowel, or anchor rodFor one way slab, main reinforcement is computed by a formula (In limit state design) that is determined by comparing compressive force as well as tensile forces Ast = 05 Fck/Fu 1√126Mu/Fckbdbd and the distribution steel is computed as 015% of Ag, for mild steel

SLAB SCHEDULE—Table on a placing drawing giving the quantity and mark of the slabs;An overview of twoway slab systems Twoway slabs are slabs that are supported on four sides In twoway slabs, the load will be carried in both directions, thus main reinforcement is provided in both directions for twoway slabs The slabs are considered as spanning twoway when the longer to shorter span length is less than a ratio of twoThe Ontario Building Code Slab Construction Slab Construction (1) Concrete shall be cast against form work in accordance with CSA 31, Concrete Materials and Methods of Concrete Construction (2) The slab shall be not less than 125 mm thick (3) The slab shall be reinforced with 10M bars spaced not more than 0 mm oc in each direction, with 30 mm clear
8153 Welded wire reinforcement (with wire size not greater than MW30 or MD30) used in slabs not exceeding 3 m in span shall be permitted to be curved from a point near the top of slab over the support to a point near the bottom of slab at midspan, provided such reinforcement5 Things to Look for When Inspecting a Suspended Concrete Slab 1 Reinforcement at Maximum Moment At the most basic level, you are checking that the reinforcement is placed in the 2 Supports are Where the Drawings Say They Are When you're walking around on top of a suspended slab deck, makeThickness of the slab is decided based on span to depth ratio specified in IS Minimum reinforcement is 012% for HYSD bars and 015% for mild steel bars The diameter of bar generally used in slabs are 6 mm, 8 mm, 10 mm, 12mm and 16mm The maximum diameter of bar used in slab should not exceed 1/8 of the total thickness of slab

Suspended slabs are made of concrete and steel mesh, the same as a ground slab They are normally prefabricated offsite, and transported by truck Some slabs have hollow channels running through them these 'hollow core slabs' are used to help reduce weight, and also to allow cabling and piping to be run through the slabThe clear cover is 15mm 2) Generally the reinforcement consists of 8mm &32—Slabsonground 33—Suspended slabs 34—Miscellaneous details Chapter 4—Site preparation and placing environment, p 3021R17 41—Soilsupport system preparation 42—Suspended slabs 43—Bulkheads 44—Setting screed guides 45—Installation of auxiliary materials 46—Concrete placement conditions Chapter 5—Materials, p
