Concrete mix estimation. Our mix-on-site concrete calculation is based on batching by volume (Large construction sites employ batching by weight which is more exact). You can also estimate the quantity of sand and gravel required by weight; Simply multiply the volumetric quantity of sand and gravel with 1400 kg/m 3 (bulk density of sand) and ...
Method 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 0.2m. Concrete = 10 x 10 x 0.2 = 20 cum. Therefore, Rebar = 80 kg x 20 = 1600 kg = 1.6 MT.
🕑 Reading time: 1 minute Concrete work in a project usually holds the maximum weightage in terms of overall cost and work quantity. It therefore becomes an important step to calculate the concrete related costs while preparing a project estimate. The cost of concrete depends upon the cost of materials, mix design, workforce, and machinery. […]

31-08-2016· If the total cost, i.e labor+equipment+shutterings+rebars+concrete, are tabulated, divided it with the total volume in order to get the per unit cost. I have no idea how much the cost of Labor, equipment, etc. in UAE - I am in KSA but basically this is the processes.
02-09-2016· Normally Rough estimate can be done by considering following. 1) % of steel volume in fiundation concrete = 1 to 3 %. 2) % of steel volume in column concrete = 2 to 5 %. 3) % of steel volume in Beam concrete = 1.25 to 3 %. 4) % of steel volume in Slab concrete = 0.7 to 1.25 % in single mesh

Beams +15%; Columns +15%; Walls +15%. Average values for typical concrete frames: Heavy industrial = 130 kg/m3. Commercial = 100 kg/m3. Institutional = 90 kg/m3. Your comments.
Maximum quantity of steel required for 1m3 concrete beam is 2%, now 2% of 1m3 = 0.02m3, and we know that 1m3 steel weight is 7850 Kg, so weight of 0.02m3 steel = 0.02 × 7850 = 157 kg, so maximum quantity of steel required for 1m3 concrete beam is 157 Kg. Quantity of steel required for 1m3 concrete Column. Thumb rule for steel in slab = 2% to 4%.

12-09-2019· Reinforced Concrete and Importance of Rebar. The structural elements in the buildings are having the internal forces namely compression, tension, bending moments and torsion. Withstanding these internal forces with low tendency for collapse and any undesirable deformation for serviceability condition is the main task of the construction materials.
As an estimating tool there are two features which par-ticularly contribute to this book: (1) It covers pra c t i c a l l y e ve r y type of concrete construction that will be encoun-t e r ed on residential, commercial and industrial build-ing including form s, re i n f o r cing steel, and concre t e placement.
16-05-2020· Rebars are used for reinforcement on a concrete structure and masonry to strengthen and help it withstand tension forces. The price is per length of rebar.
