How many concrete cubes to be taken from site for cube test?

Why the size of concrete cubes are 150mm?
Basically, the force supplied by a concrete compression machine is a definite value. For normal concrete strength application, say below 50MPa, the stress produced by a 150mmx150mmx150mm cube is sufficient for the machine to crush the concrete sample. However, if the designed concrete strength is 100MPa, under the same force (about 2,000kN) supplied by the machine, the stress under a 150mmx150mmx150mm cube is not sufficient to crush the concrete cube. Therefore, 100mmx100mmx100mm concrete cubes are used instead to increase the applied stress to crush the concrete cubes. For normal concrete strength, the cube size of 150mmx150mmx150mm is already sufficient for the crushing strength of the machine.
What is the probability that a roll of 2 number cubes roll a sum of 24?
If they are standard cubes - with numbers from 1 to 6 - the probability is 0.
How many ice cubes equal 8 lbs?
To determine how many ice cubes equal 8 lbs, we need to know the weight of a single ice cube. The weight of a standard ice cube is approximately 0.5 oz or 0.03125 lbs. To find the number of ice cubes that equal 8 lbs, we divide 8 by 0.03125, which equals 256 ice cubes. So, 256 ice cubes would equal 8 lbs.
What is the probability of rolling a pair of sixes 2 standard number cubes?
1/36
What is the Standard for Concrete cube Testing?
The standard for concrete cube testing is to put the cube under increased pressure. The pressure is increased until the cube breaks and determines the cubes compression strength.

Why does concrete bubble when wet?
I think due to the presence of Cao in the cement.... it may be the result of excessive drying of concrete cubes too...
How can you calculate the characteristic strength of concrete?
The characteristic strength of the concrete is the compressive strength of the(fck) concrete cubes of size 150 mm tested at 28 days. And compressive strength of cubes should not fall not more than 5% of this fck.
What is the probability of getting a sum of 3 when three number cubes are rolled?
If the number cubes are standard dice cubes, the odds of rolling 3 ones is 1 in 216.

How many concrete cubes?
It depends on the size of the unspecified cube size, and what and how they are to be used? More information is needed.
