Compressive Strength of Concrete Concrete Cubes | .
Concrete specimens are a cast and tested under the action of compressive loads to determine the strength of concrete. In very simple words, compressive strength is calculated by dividing the failure load with the area of application of load, usually after 28 days of curing.

Using limestone aggregates and different cements .
1/8/2005· The concrete C5 recorded the most significant loss of 44% in crushing load which was much greater than the 14% loss of the reference concrete C1. The increase in crushing load during the initial period of immersion in acid solution was likely due to continued hydration of cement and an early formation of gypsum and ettringite, which would fill the pores of concrete.

Properties of Concrete Blocks — Strength
In Taylor and Thompson''s work on concrete, a safe load of 450 pounds for concrete 1 to 2 to 4 is recommended; this allows a factor of safety of On the other hand, the Building Code of the city of Cleveland permits concrete to be loaded only to 150 pounds per square inch, and limits the height of walls of 12inch blocks to 44 feet.
