It’s 28 days strength is 40 N. The mix ratio in C40 concrete is **1: 1.5: 3**, which is same as mix ratio of M20 grade of concrete.

## Why is a bag of cement 50kg?

The reason why a **bag of cement** is of 50kgs. It’s easy to pack **cement** in **50kg bags** and supply them in big numbers when compared to **bags** smaller quantities. Because **cement** is a product which is used in large quantities in construction.

## How much concrete will one bag of cement make?

**bag** of Portland **Cement makes** 4.5 cubic feet of **concrete**. For thicknesses less than 2 inches and toppings, use: **1** part of Portland **Cement** with 3–4 parts of **concrete** sand or general purpose sand.

## Is it cheaper to mix your own concrete?
