Rcc Roof Concrete Ratio

Update your information about concrete roof tiles and shingles choose weather and fire resistant roofing material for your roof.

Rcc roof concrete ratio.

To find out the exact amount it will take to construct an rcc roof slab let s take an example. Based on the construction type ratio of tmt steel bar to concrete is. And the concrete mix ratio is 1 2 4 then to find out the construction cost you will need to calculate. Reinforced cement concrete or rcc calculator can be used to calculate m15 m20 and m25 mix ratio of cement sand and jelly.

5 part is sand and 3 part is aggregate. The proportions of materials cement sand coarse aggregate for nominal mix design mix concrete that are normally used are 1 3 6 or 1 4 8. It means 1 part of cement 1 5 part of fine aggregate coarse sand and 3 parts of coarse aggregate. This ratio of concrete also gives very high strength of cement concrete and is recommended for following works.

Concrete is an all time material for roofing. Steel required for 1000 sq ft slab steel bar calculation in roof slab reinforcement we provide there is a two types of steel bar used main bar and cross bar and know about roof slab steel calculation. Structure carries in heavy loads. Civil construction heavy industrial construction 130 kg m3.

Our mix on site concrete calculation is based on batching by volume large construction sites employ batching by weight which is more exact. If the rcc roof slab size is 25x20 sq. Simply multiply the volumetric quantity of sand and gravel with 1400 kg m 3 bulk density of sand and 1600 kg m 3 bulk density. This composition as we all know is called mixed design and varies quarry to quarry ie material properties climatic condition of that area etc hence cant say this proportion is best for this grade while thumb rules are their in existence hence foll.

100 kg of steel strengthen the structure in rcc. The ratio means for every 130 kg concrete 100 kg of steel is needed. 3 in which one part is cement 1. Failing this ratio of steel to concrete would cause weakening the structure and fatal cracks to it.

Cement concrete is strong in compressive strength but weak in tensile strength. The full form of rcc is reinforced cement concrete. Where cement concrete 1 1 5 3 is used. Simple flat roofs to sloped roofs concrete roof tiles offered various styles and colors to meet the architectural needs.

You can also estimate the quantity of sand and gravel required by weight. However you can get a rough estimate with a simple rcc roof slab steel calculation formula.
