What is the conrete mixing ratio in M25concrete?

Answer 1

The Concrete mixing ratio for M35 grade concrete as per IS Mix design is

• 1:1.6:2.907 (cement:Fineaggregate:Coarse aggregate)
  
• The ratio obtained is as per design calculations by considering the grade of aggregates and the type of cement used.
  
• The Water/cement ration is 0.43
  

Answer 2

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.
