Rcc Mixing Ratio For Roof

This ratio of concrete also gives very high strength of cement concrete and is recommended for following works.

Rcc mixing ratio for roof.

And the concrete mix ratio is 1 2 4 then to find out the construction cost you will need to calculate. To find out the exact amount it will take to construct an rcc roof slab let s take an example. 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. The strength of this mix ratio is good for most concrete slabs footings steps and foundation walls.

Like the normal concrete the ratio depends on aggregate type cement content age etc. A solid roof on building is very important for everybody living in the house. Poisson s ratio ranges from 0 15 to 0 20. For a right roof slab concreting we have to prepare proper concrete mix.

Concrete mixer and vibrator is needed. This roofing is very versatile and provides great protection. Structure carries in heavy loads. It means 1 part of cement 1 5 part of fine aggregate coarse sand and 3 parts of coarse aggregate.

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. 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. Where cement concrete 1 1 5 3 is used.

However you can get a rough estimate with a simple rcc roof slab steel calculation formula. Elastic modulus and poisson s ratio. Rcc mixture has low heat of hydration. Reinforced concrete requires very strong steel bars.

The main point to bear in mind is keep the ratio between fine aggregate and coarse aggregate should be 1 2.
