It really depends on how strong you want your blocks to be. I have seen some blocks that were made 129 blocks per bag, but that produces a porous and fragile block. My garage is built at 80 to 1 and my house at 60 to one, but it is small and single storied. So friends have gone as low as 30 blocks per bag, the blocks are strong but have little flex in them. going lower has and adverse effect on strength I am told
How many 8"X8"X16" concrete hollow block from 50 kg cement
34 PCs. of hollow blocks
20
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.
you wouldn't even need 1 bag of cement and there are also lots of variables, thickness, mix ratio, bag sizes?
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.
0.42cub.m (Cement sand mortar)
The answer depends on the size of the cement blocks which are not an international standard.
35kg
All things being equal; a bag of cement would lay 100 pieces of 5 inch blocks.
