Estimate Rebar Concrete Slab

Layout of rebar for concrete slabs to estimate the quantity of rebar in slab to strengthen concrete slabs you ll have to assess the required measure of rebar for your two dimensional shape.

Estimate rebar concrete slab.

Total length total width bar spacing exact spacing equal spacing adjusted edge clearance bar size. Calculating what you need for the sake of easy examples assume you re pouring a slab that s a simple rectangle of 20 by 30 feet and you ve figured out that you ll need the rebar set at 14 inches on center. Rebar calculator slab driveway or patio calculate the amount of rebar reinforcement needed for slabs and drive ways. Click the button to calculate the volume of concrete and man hours not including mixing needed for this job.

The grid is the horizontal and vertical spacing of your rebar. Add in walls and columns. Input length width and depth of the area. This is needed to determine both the lengths of the rebar and how many rows and columns are needed.

This calculator is to be used as an estimating tool only. Interactive scaled diagrams inch. Say 15m x 20m for simplicity as an example. Calculate rebar spacing layout and weight in a concrete slab.

Subtract the clearance from the length and width to find the dimensions of the grid. First work out your slab area. Regardless of what the particular format might be the procedure is generally the equivalent. For example if the slab is 10 x 10 and the clearance is 3 the size of the rebar grid will be 9 6 x 9 6.

Start by multiplying each of those measurements by 12 to get your dimensions in inches which in this case would be 240 inches by 360.
