For cement concrete of ratio 1 1 2 1 cement 1sand coarse sand 2graded stone aggregate require 11no bags of 50kg. Reinforced cement concrete or rcc calculator can be used to calculate m15 m20 and m25 mix ratio of cement sand and jelly. This is most important part of the structure generally 1 2 4 and 1 1 5. Contractors can cover the roof with any manner of finish tiles or shingles to help give it the desired look.

For cement concrete of ratio 1 3 6 require 4 25no bags of 50kg. This is because steeper looks tend to fit more with the golden ratio which all architects work by. If the rcc roof slab size is 25x20 sq. And the concrete mix ratio is 1 2 4 then to find out the construction cost you will need to calculate.

So if your roof rises 4 inches for every 12 inches of horizontal length then the pitch of your roof is expressed as 4 12. 3 ratios of rcc are used in construction work. A ratio of 1 1 62 is known as the golden ratio and therefore the vast majority of roof pitch in degrees charts you see will be working to this ratio at the very least. Rcc slab laying is one of major step in any type of construction so it is mandatory to know all the points related to laying rcc slab.

The way pitch also known as roof slope is measured is rise over run. For cement concrete of ratio 1 1 5 3 require 7 8no bags of 50kg. It means 1 part of cement 2 parts of fine aggregate coarse sand and 4 parts of coarse aggregate. Of course a concrete roof requires more support than a typical wooden roof.

Where cement concrete 1 2 4 is used. How many bags of rcc ratio 1 2 4 be used to cost of roof slab in one cu m or 35 3147 cu ft. A ratio is the most common way of expressing roof pitch or roof slope but degrees are also possible. For cement concrete of ratio 1 2 4 require 6 no bags of 50kg.

For best cement sand plaster on brick rcc.
