How many chb can make in one cement bag?

The number of concrete hollow blocks (CHB) that can be produced from one standard 40 kg bag of cement typically ranges from 30 to 40 blocks, depending on the mix ratio and size of the blocks. A common mix ratio is 1 part cement to 6 parts aggregate, which can affect the final count. Additionally, the size and thickness of the blocks will also influence the total output. Always check local guidelines and standards for precise calculations.
