Example calculation estimate the quantity of cement sand and stone aggregate required for 1 cubic meter of 1 2 4 concrete mix.
Roof slab concrete ratio of concrete mixture.
M25 grade concrete ratio is 1 1 2 mixture of cement fine aggregates and course aggregate in which one part is cement one part is sand and two part is aggregate.
The strength of this mix ratio is good for most concrete slabs footings steps and foundation walls.
Used as reinforced cement concrete rcc.
As such it can productively be used in a wide variety of weight bearing projects.
Its compressive strength is 20 mpa.
The 1 2 3 ratio s make up is described right in its name.
1 sand part 2aggregate part.
Concrete mix ratio for beams.
Concrete mix ratio for roof slab.
That is because it is among the most versatile mix ratios regardless of what scale it is being used at.
The 1 2 3 concrete mix ratio is considered the classic mix ratio by many professional builders.
As we know that roof slab is rcc structure so we can use minimum grade of m20 grade and concrete mix ratio 1 1 5 3 for roof slab maximum grade of concrete m25 m30 and much higher are used as per design for roof slab.
M25 grade mixing ratio is 1 1 2 1cement part.
Mixing ratio is 1 1 5 3 1cement part.
Standard grades of concrete.
1 1 5 3 m20 is concrete mix ratio used for roof slab.
There are two types of m25 concrete ratio concrete mixes nominal mix and design mix.
For general rcc work in buildings bed plates lintels rcc shelves pavement etc.
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.
Materials required are 7 nos.
Its compressive.
Concrete mix ratio compressive strength is the most important property of hardened concrete.
Where cement concrete 1 2 4 is used.
This ratio of cement concrete gives high strength of cement concrete and is recommended for following works.
Used for construction of slabs beams columns etc.
It means 1 part of cement 2 parts of fine aggregate coarse sand and 4 parts of coarse aggregate.
