The M15 grade of concrete typically has a mix ratio of 1:2:4, which means 1 part cement, 2 parts sand, and 4 parts coarse aggregate. The cement content for M15 concrete is generally around 240 kg per cubic meter of concrete. However, this can vary based on specific project requirements and local practices. Always consult relevant standards and guidelines for precise specifications.

What is the minimum content cement in RCC?
The minimum cement content in reinforced cement concrete (RCC) typically varies depending on the application and environmental conditions, but it is generally around 300 kg/m³ for structural applications. In aggressive environments, this value may need to be increased to ensure durability and strength. For specific projects, local building codes and standards should always be consulted to determine the precise minimum requirements.
What is the ratio of cement sand and aggregate in M30 mix of concrete?
The ratios of cement to sand to aggregate for the different grades of concrete are as follows. M10 has a ratio of 1:3:6. M15 has a ratio of 1:2:4. M20 has a ratio of 1:1.5:3. M25 has a ratio of 1:1:2, but M30 has no set ratio. It is a designed mixture to achieve the stress tolerance desired.
What is the cement content for M7.5 grade concrete?
For M7.5 concrete, the common mix ratio is 1:4:8. This means:1 part cement 4 parts fine aggregates (sand)8 parts coarse aggregates. These ratio is by volume.
How the changing of workability when the concrete mixture containing high aggregate content?
Aggregate to cement ratio is an important thing which affects the workability....! If the aggregate/cement ratio is higher , the concrete will be Leaner. Less quantity of paste is available for lubrication, Hence workability decreases..!! On the other hand if the aggregate/cement ratio is lower, the concrete will be fatty. Higher quantity of paste is available for lubrication. Hence workability increases. ! Thus Higher aggregate content leads to lowering of workability....!

What can you add to Portland cement to make it sulphate resistant?
The sulphate resistant cement is made with low C3A content is found to be effective.Such cement with low C3A and comparitively low C4AF content is known as sulphate resisting cement.This cement has a high silicate content.The specification generally limits the C3A content to 5 percent.
