you wouldn't even need 1 bag of cement and there are also lots of variables, thickness, mix ratio, bag sizes?
How many 8"X8"X16" concrete hollow block from 50 kg cement
34 PCs. of hollow blocks
0.42cub.m (Cement sand mortar)
There are many different formulas for concrete blocks, depending on what they will be used for. One of the more common formulas is one part Portland cement, 2 parts sand, and 1 part gravel.
One bag of cement, typically weighing 94 pounds (42.6 kg), can produce approximately 30 to 40 standard concrete blocks, depending on the specific mix design and the size of the blocks. Standard concrete blocks usually measure 16 inches by 8 inches by 8 inches. The exact number can vary based on the proportions of cement, sand, gravel, and water used in the mix.

While concrete has been used as a building material for many centuries, concrete hollow blocks have only been manufactured since the early 1900s. These blocks are used in all types of building projects.
The answer depends on the volume of the hollow.
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.

The number of concrete blocks that a 25 kg bag of cement can produce depends on the size of the blocks and the mix ratio used. Typically, a 25 kg bag of cement can produce about 6 to 10 standard concrete blocks (usually 400 mm x 200 mm x 200 mm) when mixed with sand and aggregate in a common ratio. However, this can vary based on the specific mix design and the density of the materials used.
To calculate the number of concrete hollow blocks needed for a 10 square meter wall, first determine the size of the blocks. A standard concrete hollow block typically measures 0.39 meters by 0.19 meters, which is approximately 0.0741 square meters per block. For a 10 square meter wall, you would need around 135 blocks (10 ÷ 0.0741 ≈ 135.2), assuming no waste or openings. However, it's wise to account for a 10% waste factor, bringing the total to about 150 blocks.
The number of hollow blocks that can be filled with 1 bag (50 kg) of cement varies based on the size of the blocks and the mix ratio of the mortar. Generally, a 50 kg bag of cement can produce enough mortar to fill approximately 30 to 40 standard hollow blocks, assuming a typical mix. It's important to consider factors like water content and aggregate size, which can affect the final yield. Always consult specific guidelines for the materials you are using for the most accurate estimate.
