The Concrete mixing ratio for M35 grade concrete as per IS Mix design is
The mix ratio for Grade 25 concrete is generally specified by the characteristic compressive strength of the concrete at 28 days, which is 25 megapascals (MPa) or 3625 pounds per square inch (psi). The mix ratio is typically denoted by the proportion of the main ingredients used to produce the concrete, including cement, aggregates, and water.
The mix ratio for Grade 25 concrete can vary depending on the specific requirements and local practices. However, a commonly used mix ratio for Grade 25 concrete is:
1 part cement: 2 parts fine aggregate (sand): 4 parts coarse aggregate (gravel)
This mix ratio corresponds to a concrete mix that uses one part cement, two parts fine aggregate (sand), and four parts coarse aggregate (gravel) by volume. The amount of water added to the mix will depend on the desired workability of the concrete and the moisture content of the aggregates.
It's important to note that different regions or countries may have variations in the mix ratios for concrete of the same grade. Moreover, the mix ratio can be adjusted based on specific project requirements, such as the strength, durability, and workability needed for the particular application.
To ensure the best results, it is recommended to consult with a qualified civil engineer or concrete mix designer who can provide a mix design tailored to the project's needs and in accordance with local standards and practices. Additionally, proper quality control measures should be in place during concrete production to achieve the desired characteristics and performance of the Grade 25 concrete.

What is mixing ratio for concrete grade 30
The grading of aggregate influences the mix proportions for a specified workability and water-cement ratio. Coarser the grading leaner will be mix which can be used. Very lean mix is not desirable since it does not contain enough finer material to make the concrete cohesive. The type of aggregate influences strongly the aggregate-cement ratio for the desired workability and stipulated water cement ratio. An important feature of a satisfactory aggregate is the uniformity of the grading which can be achieved by mixing different size fractions.
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.
Why does concrete mix with low water cement ratio resulted in hardened concrete having higher strength than those with high water cement ratio?
The answer is actually called: The mixing ratio.
