CHB - Concrete Hollow Blocks

[gary505]

Can anyone tell the standard size(s) of concrete hollow blocks in the Philippines, particularily in Mindanao. I've seen some photos of construction that looks like 18x8x8 inch blocks, but I've also heard of 12 inch and 18 inch blocks. Which would be used in the rural regions of Mindanoa? Thanks!

Standard sizes are 40 cm in length and 20 cm in height. Depth is a nominal 4, 5 and 6 inches. These are the standard sizes used throughout the country. And these blocks are not load bearing. A kid can break these blocks with a karate kick.
