How do you find the mix design of concrete?
Procedure for Concrete Mix Design of M25 Concrete
- ftarget = fck + 1.65 x S.
- = 25 + 1.65 x 4.0 = 31.6 N/mm2
- Cement Content = (197.4/0.5) = 394.8 kg/m3
- Cement content = (197.4/0.55) = 358.9 kg/m3
Is 10262 method of mix design?
Procedure for concrete mix design calculation as per IS 10262-2009 based on strength and durability, workability, economy is discussed in this article. To produce concrete of required strength and properties, selection of ingredients and their quantity is to be found which is called concrete mix design.
Which of these data is required for the design of concrete mix as per IS 10262-2009?

Is code 10262 new?
IS 10262-2019 is a comprehensive code for standard and high-performance concrete mix designs. Guidelines for proportioning raw materials for concrete to achieve the desired strength are provided in this IS Code.
How do you find the ratio of a mix design?
Concrete Mix Design Calculation
- Target Mean Strength = 50 + ( 5 X 1.65 ) = 58.25 Mpa.
- Selection of water cement ratio: Assume water cement ratio = 0.35.
- Calculation of water content: Ad.
- Calculation of cement content: Water cement ratio = 0.35.
- Calculation of Sand & Coarse Aggregate Quantities:
Is mix design a procedure?
While a concrete mix design is a process of selecting ingredients for a concrete mixture and deciding on their proportions. When designing a mix, you should always consider the desired strength, durability, and workability of the concrete for the project in question.
What is the procedure of mix design?
Is method of mix design procedure?
The compaction factor for the design mix is taken as 0.9. The maximum size of aggregate is 20 mm (angular)….Materials and Methods.

Is method of mix design?
The various methods of mix design are applied for determining the qualities & quantity of concrete. The objective of designing a mix is to produce a concrete of required strength, durability and workability as economically as possible.
