### Compression Test on Concrete - Building Research …

The prismoidal compressive strength of concrete has been found to decrease with the increase in the ratio of height 'h' to lateral dimension 'd' till it reaches a value of 4 (h/d=4), beyond which it approximately remains constant equal to 0.7 times the strength of cube for which h/d ratio equals to unity.
