15kg/mm2 means 1.5N/mm2.

Am I right?

The individual variation of test reading should not exceed 15% of the average.

Sagar said:   7 years ago
What action shall be taken if the sample result is invalid based on individual variation is more than 15% despite having the individual test result is 35.17 mpa for M30 grade concrete.

Shall one go for in situ tests?

Please explain me.
