Yes. That's what they're designed for.
It is a wall constructed from individual small concrete blocks. It may be steel reinforced or not depending on application. They are quick to erect.
The maximum thickness of a reinforced concrete wall is 203 mm.

The hollow block sizes in the Philippines are the following:40cm (length) X 20 cm (width) X 4 in (thickness)40cm (length) X 20 cm (width) X 5 in (thickness)40cm (length) X 20 cm (width) X 6 in (thickness)
classification of concrete blocks
Traditional Concrete Masonry Unit (CMU) Blocks have 2 rectangular voids through the block. These voids are called "Cells". The face shell thickness is the thickness of the block material from the cell to the front of the block. For example, a typical block of dimensions 8"high by 8"deep by 16" long probably has a face shell thickness of 1.25".
The answer depends on how much of the block is hollow.

The dry joint is hollow block work is called a mortar joint. After the blocks are stacked, they are filled with concrete.
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.
Yes- because they are not a solid block of concrete- they are hollow with a large air space. The weight of the water displaced is greater than the weight of the hollow concrete hull, and it will float.
