Which grade of concrete is used for?
Different types of concrete grades and their uses
| Concrete Grade | Mix Ratio (cement : sand : aggregates) | Compressive Strength |
|---|---|---|
| M10 | 1 : 3 : 6 | 1450 psi |
| M15 | 1 : 2 : 4 | 2175 psi |
| M20 | 1 : 1.5 : 3 | 2900 psi |
| Standard Grade of Concrete |
What are different concrete grades?
Regular grades of concrete are M15, M20, M25 etc. For plain cement concrete works, generally M15 is used. For reinforced concrete construction minimum M20 grade of concrete are used.
What is C20 concrete used for?
C20 concrete is often used for lightweight domestic and commercial construction, as well as for projects where the ground may be unstable. Because of its lightweight nature, this mix is best used for applications such as: Slab foundations — for small houses garages and extensions. Patio paving.
Where do we use M20 grade concrete?
Also good for workshop bases, garages, driveways, and internal floor slabs. Construction in all areas. Multi-purpose concrete mix, usually used for foundations. Pathways and roadways (this is the lowest grade concrete mix that can be used for this purpose).
What concrete grade is used for slabs?
M 25, M 30, M 35 are used for RCC ( Reinforced Cement Concrete ) like foundations, footings columns, beams, slabs etc. M-40 grade is used for Pre-stressed concrete work, slabs, beams, column, footing etc.
Which is better M20 or M25?
Modulus of elasticity of the M20 concrete is 22360MPa and M25 grade concrete is 25000Mpa. The behavior of M25 concrete is stiffer than M20. It can take more loads.
Which grade of concrete is used for slab?
Generally M10 and M15 grades of concrete are used for leveling course, and bedding for footings. Standard concrete and concrete of grade M20 is applicable for Reinforced Cement Concrete (RCC) works for slabs, beams, columns and so on. The high strength concrete has its applications for high rise buildings.
Which grade of concrete is used for foundation?
What is C7 5 concrete used for?
Lean Mix – Trench fill. Volume where no strength is needed. C7. 5 (formally called ST1) – A mix used for stabilising underground pipe work or for use as a dry backing when installing roadside kerbing, when erecting posts or for general use where no real strength is required.
What is GEN3 concrete?
GEN3. Gen 3 is commonly used for light duty domestic applications and foundations. It can be used to construct internal floor slabs that contain no embedded metal and will be covered by carpet, tiles or laminate flooring.
Which grade is used for slabs?
Generally M10 and M15 grades of concrete are used for leveling course, and bedding for footings. Standard concrete and concrete of grade M20 is applicable for Reinforced Cement Concrete (RCC) works for slabs, beams, columns and so on.
