What is M15 and M20 grade concrete?
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 is used. DIFFERENT GRADES OF CONCRETE. Mix Ratio.
What is M20 concrete?
M20 concrete mix ratio:- M20 concrete mix ratio is 1:1.5:3, made of mixture of cement, sand and aggregate in which one part is cement, 1.5 part is sand and 3 part is aggregate or stone. It means 1 bag of cement mixed with 1.5 bag of sand and three bag of aggregate to make concrete mix of M20 grade of concrete.
What is M15 grade of concrete?
1 : 2 : 4
Different types of concrete grades and their uses
| Concrete Grade | Mix Ratio (cement : sand : aggregates) | Compressive Strength |
|---|---|---|
| M15 | 1 : 2 : 4 | 2175 psi |
| M20 | 1 : 1.5 : 3 | 2900 psi |
| Standard Grade of Concrete | ||
| M25 | 1 : 1 : 2 | 3625 psi |
What is the meaning of M 20?
Answered by Mathew Roy T more than 6 months ago. M20- M stands for Design Mix And 20 stands compressive strength of concrete after 28 days curing.
Which concrete grade is best for slab?
GRADE: C25 CONCRETE
- Strength: 25 Newtons after 28 days.
- A multi-purpose concrete that is used on a wide range of commercial and domestic construction sites. C25 is often used when pouring foundations (footings). It is also the ideal concrete for domestic slab foundations for house and bungalow floors.
What is m30 cement?
∴ In the designation of a concrete mix, the letter ‘M’ and the number stands for Mix and characteristic compressive strength of 150 mm cube at 28 days. ∴ The M 30 grade of concrete means the concrete mix which attains 28 day strength (characteristics) as 30 MPa or 30 N/mm2.
What is the cost of M15 concrete?
Ultratech M15 Ready Mixed Concrete, Grade Standard: M15, Rs 3800 /cubic litre | ID: 19339560173.
What is the meaning of M10 M15 M20 grade of concrete?
, Student-Civil Engineering. M10 M15 M20 etc. are all grades of concrete, The ‘M’ denotes ‘Mix’ followed by a number representing the compressive strength of that mix in N/mm^2. A mix is a specific ratio in which cement, fine(sand) and coarse aggregate(gravel) are mixed.
What is the difference between M15 M20 M25 and M35?
M15 = 15N/mm2 compressive strength after 28days. M20 = 20N/mm2 compressive strength after 28days. M25 = 25N/mm2 compressive strength after 28days. M30 = 30N/mm2 compressive strength after 28days. M35 = 35N/mm2 compressive strength after 28days. M40 = 40N/mm2 compressive strength after 28days.
What is the compressive strength of M25 grade concrete?
The grade M25 grade concrete has a compressive strength of 25n/mm2 within 28days of curing. USAGE AND APPLICATION OF M25 GRADE CONCRETE: M25 grade concrete gets also used as an RCC, the Reinforced cement concrete. M25 is used majorly during the construction of slabs, columns, footing, or beams.
What is the mix ratio of M20 grade concrete?
PROPERTIES OF THE M20 GRADE CONCRETE: The M20 Grade Concrete comes in a mix ratio of 1:1.5:3.1 cement.1.5 sand and three aggregate. TheM20 stands for the mixture of aggregate, sand, and cement prepared so as the whole cement concrete cube of size becomes 154 cm by 15cm by another 15 cm.
