If two cubes of different sizes but prepared from the same concrete, are tested then they will show different test results. For example, strength of a cube specimen having 10 cm in size is 10% less than strength of a cube specimen having 15 cm in size.If two cubes of different shapes (such as cube & cylinder) are tested, then they will show different test rSee more on civilblog

Measurement of Concrete StrengthFactors Affecting Concrete StrengthA More Detailed Look at Concrete StrengthTraditionally, this is done by preparing concrete cubes or prisms, then curing them for specified times. Common curing times are 2, 7, 28 and 90 days. The curing temperature is typically 20 degrees Centigrade. After reaching the required age for testing, the cubes/prisms are crushed in a large press. The SI unit for concrete strength measurement is the Mega Pascal, although 'Newtons per square millimetre' is still widely used as the See more on understanding-cement
