  • 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 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.
