In this lecture, I'll show you how to figure out how much cement, sand, and aggregate is needed for any grade of concrete (M10, M15, M20 & M25), and at the end, I will provide you the excel sheet of this calculation in which you will only need to put the input values to get the results for all grades of concrete. Calculating the quantity of materials needed for any grade of concrete is simple. All you have to do is follow this simple procedure. The procedure is done with the following steps;
1) Calculate the volume of concrete (wet volume)
Volume = Length x Width x Height
2) Calculate the dry volume by using the formula;
Dry volume = Wet volume x 1.54
3) Volume of cement required;
Volume of cement = Ratio of cement/total ratio x dry volume
Number of cement bags required;
No of cement bags = Volume of cement/volume of 1 bag of cement
4) Volume of sand required;
The volume of sand = Ratio of sand/total ratio x dry volume
5) Volume of aggregate required;
The volume of aggregate = Ratio of aggregate/total ratio x dry volume
