Different Concrete Grades and What They Are Used For

- C10 Concrete Grade. C10 is also known as Gen 1 concrete and is designed with a 10 Newton/28 day strength.
- C15 Concrete Grade.
- C20 Concrete Grade.
- C25 Concrete Grade.
- C30 Concrete Grade.
- C35 Concrete Grade.
- C40 Concrete Grade.

**What is C15 concrete mix ratio?**

For nominal mix, ratio of C15 concrete grade is 1:2:4 by volume, in which one part is portland stone cement mixed with 2 part of fine aggregate/sand and 4 part of coarse aggregate with required quantity of water to reach compressive strength 15 Newton per square millimetre (N/mm2) or 15 MPa at 28 days curing of a …

**What is the ratio of M40 grade concrete?**

### What is the application of 1/3 3 ratio?

One of the best concrete mixing ratios for a slab is 1 : 3 : 3 (cement : sand : stone), this will produce approximately a 3000 psi concrete mix. This mixing ratio is excellent for a shed slab but it’s also good for most concrete patios, footings, steps, and foundation walls.

### What is the ratio of m25 grade concrete?

Nominal mix ratio of m25 grade of concrete is 1:1:2, mixture of cement, sand, aggregate and water in which one part is cement, one part is sand and two part is aggregate and water cement ratio is 0.4 to 0.6.

**What is ratio of M40?**

40 MPa (After 28 Days) Material. Cement, Water, Aggregates, Sand, Admixture. Concrete Grade Mix Ratio. 1 Ratio 1.3 Ratio 2.6 (Cement, Water, Aggregates)

**What is C10 concrete mix?**

GEN 1 / C10 concrete is a very lightweight mix which can be used for a variety of non-structural applications. The standardised mix has a strength rating of 10 newtons after 28 days and is commonly used in domestic projects – but can also be used for commercial applications.
