In this tutorial, i have explained briefly How to calculate Cement sand and Aggregate quantity in the concrete slab. This tutorial is beneficial for not only the engineers working on site but also for those people who plan to build their homes and other establishments so that they can know How to calculate the quantity of materials in concrete and estimate the quantity of cement, sand, and aggregate required by themselves. This enables them to minimize the expenses on construction by reducing the construction cost. It is quite easy to calculate the amount of cement, sand, and aggregate required for the construction of slabs. Everyone and not only the engineers can calculate it and that too just while sitting back at home. After watching the complete tutorial you will be able to calculate the quantity of materials in slab for any grade of concrete. By using this method you will also know how to calculate Cement sand and aggregate for m20 grade concrete. PS: The procedure shown in this video is for PCC Slab (without steel) M15 is used for plain Cement concrete. For RCC Slab you can use the minimum grade M20(1:1.5:3) and do the calculations accordingly. Regards!
