Rcc Mixing Ratio For Roof

To find out the exact amount it will take to construct an rcc roof slab let s take an example.

Rcc mixing ratio for roof.

Where cement concrete 1 1 5 3 is used. One of the best concrete mix ratios is 1 part cement 3 parts sand and 3 parts aggregate this will produce approximately a 3000 psi concrete mix. It means 1 part of cement 1 5 part of fine aggregate coarse sand and 3 parts of coarse aggregate. The strength of this mix ratio is good for most concrete slabs footings steps and foundation walls.

Poisson s ratio ranges from 0 15 to 0 20. This roofing is very versatile and provides great protection. A solid roof on building is very important for everybody living in the house. Reinforced concrete requires very strong steel bars.

If the rcc roof slab size is 25x20 sq. Rcc mixture has low elastic modulus because the heat of hydration generated is proportional to elastic modulus. The minimum grade of concrete for plain cement concrete pcc is m15 the minimum grade of concrete for reinforced cement concrete rcc is m20 concrete grade and mix ratio table as per is 456 2000 the grades less than m20 should not be used in rcc works. This article provides a brief view of steel bars in cement concrete work.

And the concrete mix ratio is 1 2 4 then to find out the construction cost you will need to calculate. Size of aggregates mm water for dry aggregates liter water for aggregates condition from dry to moist batch liter water for best consistency liter small precast work fence posts poles garden furniture and other work of very thin sections. Structure carries in heavy loads. Like the normal concrete the ratio depends on aggregate type cement content age etc.

This ratio of concrete also gives very high strength of cement concrete and is recommended for following works. Enough water should be collected in water tanks. However you can get a rough estimate with a simple rcc roof slab steel calculation formula. Rcc mixture has low heat of hydration.

For a right roof slab concreting we have to prepare proper concrete mix.
