A mixing ratio of concrete

What if you wanted to install your concrete slab and didn’t know what steps to take? Don’t worry and read this article. Surely, you will find the best concrete mix ratios. 

Getting the right concrete mix ratio is very important.

We will try below to guide how to mix concrete for different applications, whether for foundations, garden walls, or patios.

For long-lasting, good-quality work, you need to mix the concrete and get the right concrete mix ratio. Moreover, to turn that target off, we will help you determine the exact amounts to a better mix.

What is Concrete?

Concrete is a mixture of cement with sand, stone/aggregate, and water. This mixture builds up a paste that can be used to mix building materials together.

The proportion of the mixture of cement, sand, stones, or aggregates determines concrete strength.

On the market, there are different qualities of concrete, which vary according to these ratios (M10, M20, M30, M35, etc.).

When the amount of water is large, the workability of concrete will be high, and concrete strength will be reduced. On the other hand, when the quantity of water is too low, the water’s workability will decrease. Therefore, the amount of water required may vary for different grades of concrete. Therefore, it is necessary to make a balanced mixture of concrete.

Different concrete mixes:

There are different concrete mixes for different environments. 

C10 concrete: for a domestic and commercial environment. It is used for patio slabs, pedestrian paths, and domestic exterior work.

Concrete C15: for a domestic and commercial environment.

It is used for border edging and floor fasteners in home environments and small commercial projects.

Concrete C20 is used to build strong and durable floor foundations. It has a high resistance level. So it is able to withstand the heavyweight of machinery and heavy work. It is ideal for aligning floors in garages, walkways, and workshops.

C25 concrete: for a mainly domestic environment

 C25 is for use in all concrete construction requirements, building foundations, and flooring.

C30 concrete: for a domestic and commercial environment

It is used in the construction of roads, driveways, and heavy flooding.

Concrete C35: for a commercial environment.

It is a very strong concrete and able to withstand constant pressure. It is used to construct exterior walls to support buildings, structural piles, and multi-story parking lots.

C40 concrete: for a large-scale commercial environment

C40 concrete is the strongest and most durable mix. It is used for creating solid and supporting beams and foundations for huge buildings and heavily trafficked roads. It is ideal for farm and laboratory environments.

What Is a Concrete Mix Ratio?

The manufacture of concrete requires four main basic materials: cement, sand, aggregate, water, and an additional mixture.

This mixing ratio is an important factor in determining the compressive strength of the concrete mix.

In order to have a strong, durable, and long-lasting concrete mix, the correct concrete mix ratios must be used.

To produce a concrete mix of around 2,500 to 3,000 psi, you can make a concrete mix ratio of 1 part cement, 1 part sand, and three parts aggregate. This mixture will form a paste, which will bind the materials together with water until a mixture hardens. You have to put into consideration that the more water you use to mix this concrete, the weaker the concrete mix, and the less water you use to mix this concrete, the stronger the concrete mix.

Types of concrete mixing ratio:

According to IS code 456-2000; generally, there are three types of concrete mixing ratio.

Nominal Concrete Mix Ratios:

Nominal mixes are mixtures of the fixed ratio of cement, sand, and aggregates, ensuring adequate strength.

These blends provide simplicity.

This nominal mixing ratio is designed for small scale constructions and is prefixed and specified.

Standard mixing ratio:

According to Indian standards (IS 456–2000), concrete mixes have different qualities ranging from M5 to M40. Of which M denotes mix, and the numbers (from 5 to 40) indicate the strength of Mix N / mm2.

M30 to M45 grade standard concrete mixing ratio is manually designed.

For M45, the amount of cement, sand, and coarse aggregate are batched by volume according to the design mix.

High Strength Concrete Mix Ratio

The high strength concrete mixing ratio is M50 to M70 grade and is designed by hand.

For M70, the amount of cement, sand, and coarse aggregate are batched by volume according to the design mix.

Mixing ratios used for concrete of varying strength

Concrete mixing ratios are accurate. They are obtained while measuring dry materials using buckets, for example.

Therefore, we will get a uniform concrete mix for the whole project by measuring the cement, stone, and sand.

When you use less water to mix concrete, the concrete mix will be stronger.


For a 3,000 psi cubic yard of concrete, the concrete mix ratio requires:

234 kg of cement

707 kg of sand

725kg of stone

132L of water

This concrete mix is ​​strong and durable.


For a 4000 psi cubic yard of concrete, the concrete mixing ratio requires:

277 kg of cement

 657 kg of sand

 725kg of stone

 133L of water

This concrete mix is ​​strong and ideal for driveways, pool decks, sidewalks, and commercial garages.


In order to make a strong and durable concrete mix, it is important to use the best concrete mix ratios to produce

The four basic materials needed for this mixture are cement, sand, aggregate (stone), and water.

To ensure that the expected results are strong, lasting, and accurate every time, you should follow the tips we presented to you above.

To conclude, In this article, we have taught you the information you need to manufacture the best concrete mix ratios successfully.
