Quantity measurements can frequently be a little off so we highly recommend ordering a little extra because coming up short can be a disaster a good rule of thumb is take your calculation and add 4 to 10 to the total to account for waste spillage overexcavation settlement spreading of forms loss of entrained air or any other changes in volume
2 ensp enspthe steel rebar is widely used as a tensioning tool to reinforce concrete structures it helps to strengthen the concrete and hold it in a tensioned state as well as it carries the tensile loads of the structure these elements of the structure are commonly supplied with the patterned surface which mechanically forms a firm bond with the concrete
Calculate the amount of rebar needed for reinforcing a wall this calculator assumes that you are using 20 foot long lengths of rebar if your wall is over 20 feet long it will add the amount of overlap required if your wall is over 40 feet long it will add 2x the amount of overlap required
2018411ensp enspwhen youre pouring any kind of concrete slab flooring in or around your home youll need to create a rebar grid first to reinforce the tensile strength of the concrete learn how to estimate the amount of rebar youll need before you purchase your materials to save time and money
Estimation of steel reinforcement quantity for concrete slab footing and column beams etc is crucial for the cost evaluation for the construction design drawings are used as a base for computing rebar quantity in different structural elements this article presents steel quantity computation process for slabs columns and footings contentscalculate steel quantity for slabcalculate steel
2017126ensp enspquantity estimation of materials is essentially required in any construction works and quantity of materials depend on the mix proportions of the concrete in our previous article we have already discussed how to calculate bricks in a wall today we will discuss how to calculate quantities of materials for different mix ratio of concrete

Methods of reinforcement quantity estimation there are different methods for estimating the quantities of reinforcement three methods of varying accuracy are method1 reinforcement estimation thumb rule method this simplest method is based on the type of structure and the volume of the reinforced concrete elements
2019623ensp enspmethod 1 you can make a rough estimate by using thumb rule that about 80 kg of rebar is required per cum of slab so if slab size is say 10m x 10m x 02m concrete 10 x 10 x 02 20 cum therefore rebar 80 kg x 20 1600 kg 16 mt method
