M10 concrete is a standard grade of concrete defined by its specific strength and mix proportions.
Understanding Concrete Grades
Concrete is classified into different "grades" based on its compressive strength after 28 days of curing. This strength is measured in Newtons per square millimeter (N/mm²). The grade designation starts with the letter 'M', which stands for "Mix," followed by a number indicating the characteristic compressive strength.
Defining M10 Concrete
Based on the provided reference, M10 is a grade of concrete. This means that the compressive strength of M10 concrete, when tested after 28 days of curing, is 10 N/mm². This 28-day strength is a crucial parameter for engineers to ensure the concrete is suitable for its intended use.
The M10 Mix Ratio
A key characteristic of M10 concrete is its standard nominal mix ratio. The reference states that M10 concrete's ratio is 1:3:6. This ratio represents the proportions of the main components by volume or weight (though typically volume for nominal mixes like this) in the following order:
- Cement: 1 part
- Sand (Fine Aggregate): 3 parts
- Coarse Aggregates: 6 parts
This specific ratio helps achieve the target 10 N/mm² strength under standard conditions and proper water-cement ratio.
M10 Concrete Mix Components
The table below summarizes the components and their proportions in the M10 mix:
| Component | Proportion |
|---|---|
| Cement | 1 part |
| Sand | 3 parts |
| Coarse Aggregate | 6 parts |
In summary, M10 concrete is defined by its 10 N/mm² compressive strength at 28 days and its common 1:3:6 mix ratio of cement, sand, and coarse aggregates.
