15 x 20 x 40 cm. CHB wall
find the area of the wall
A= 35 x 7
A= 275 sq. m.
1 sq. m. of a wall consist of 12.5 pcs of CHB
275 x 12.5 = 3,437.5 pcs of CHB
How to estimate concrete hollow blocks or CHB
A wall has a dimension of 35 meters long and and 7 meters high specify the use of 15 cm. concrete hollow blocks. Prepare a comparative bill of materials for CHB.

Thanks for the good example. This will be useful for checking and calculating new construction works on hollow blocks.
What is cheaper a concrete wall or a combination of concrete and mesh wire
35 x 7 is not 275 sq m. computations are way off.
standard computation of cement and sand for one hollow block????
s myxomatosis was introduced to control the rabbits, the fence still remains and but is now called The State Barrier Fence of WA. You can read more about it vinyl chain link fence
Is there any other standard of computation in using CHB? I read on other article that 10pcs of CHB for 1 sq.m., and this article is difference?
35*7 is not 275, it's just 245. Be thoughtful in giving ideas pls.
yes i noticed that the computation has an error
35 x 7 = 245
245 x 12.5 -= 3062.5 CHB
What kind of Computations do you have?
How do u get 12.5?
1sq.m wall area / 0.08sq.m chb area = 12.5pcs of chb
if you have 35m X 7m wall, you need to find the area of your wall, 35X7=245sq.m,
Then, 245sq.m X 12.5pcs of chb = 3,062.5 pcs of CHB
It is imperative that we read blog post very carefully. I am already done it and find that this post is really amazing. concrete contractors york pa
Estimating concrete hollow blocks (CHB) requires calculating the number needed per square meter. Measure the area and divide by the block's size for accurate estimation.AV Lancaster Concrete Co.
