What is the normal compressive strength of hollow

Failure Stress = Uniaxial Compressive Strength = Force / Area It should also be noted that concrete strength is more normally found by measuring "cube strength", that is where the concrete is pored into cube shaped moulds of 100 mm x 100 mm x 100 mm and is then allowed to cure for a period of time (typically 28 days).

Properties of concrete - Wikipedia

2019-10-14  Concrete tests can measure the "plastic" (unhydrated) properties of concrete prior to, and during placement. As these properties affect the hardened compressive strength and durability of concrete (resistance to freeze-thaw), the properties of workability (slump/flow), temperature, density and age are monitored to ensure the production and placement of 'quality' concrete.
