what is the compressive strength of a lightweight concrete hollow blocks

Testing of Concrete Blocks - Civil Engineering Portal ...

Concrete can be converted into precast masonry units such as Hollow and Solid normal and light weight concrete blocks of suitable size to be used for load and non-load bearing units for wallings. Use of such concrete blocks are more appropriate in region where soil bricks are costly, poor in strength and are not available.
