This post contains a detailed procedure of concrete mix design using concrete mix design calculator application as per IS -456:2000 and IS - 10262:2009.
M-25 is the most common design mix in routine construction work. Learning this is an essential step for becoming an excellent civil engineer, whether at site or for your degree courses. Here you will learn to design this through our concrete mix design calculator application and apply this knowledge to your practice.
The Concrete Mix Design calculator app will help you quickly grasp the concept of mix design as it is effortless to use and has an excellent graphical interface. Here you can go a step further by varying the parameters and analysing the effect in design to get a in depth knowledge.
In this tutorial, you'll learn:
What M-25 means?
Important steps involved in the design.
How to effectively set different parameter to get efficient design?
To get the most out of this tutorial, you should know characteristic strength, MSA, Moisture content, Specific gravity, and Dry volume. Having some understanding of these concepts will greatly help you understand the new ones you'll be exploring in this tutorial.
The different design stipulations required for the desired mix are shown in the table below:

Different steps involved in concrete mix design of M25 using concrete mix design calculator application are as follows:
Download : Download the application from play store and install it. Once you are done with the installation, open the application and select the first option "Design mix" -to design a concrete mix as per IS 10262:2009.
Background data: Check the details of each entity by just clicking on it. For example if you want to know more about the type of concrete. Then just click on the entity and you will get the details like this.
Input parameters: Input the data as per the problem. The different stipulations for proportioning, data of sieve analysis of aggregates, data of chemical admixtures if applicable, and also the different test data for materials.
One click: Next just press the play symbol, to get the final output.
Remark: The application will also let you know if you have entered an incompatible combination of exposure conditions and grade of concrete as per Indian standards correct it and again press the play symbol, to get the final output.
We hope you understand the concept of design and how to set a parameter to create a design mix of M-25. Further, you can use the concrete mix design calculator app to change the parameter and study the effect on the design mix.
In conclusion, the detailed calculation of M25 concrete mix design using IS 10262:2009 and IS 456:2000 is a crucial aspect of construction. The concrete calculator makes the process much easier and more efficient.
Some of the major key points are as follows:
Advantage of using calculator: Proper calculation and design will go a long way in ensuring that the project is completed on time and within budget, while also meeting the required standards.
Detailed calculation: Yes, you will also get the complete calculation of the mix design. Just you have to go back from this final output page to get the complete calculation.
If you again go back then you will be directed to the input page. You can repeat the design using different problems.
