I know full strength of concrete gain after 28 days.

Sujeet dubey said:   8 years ago
For testing of cube = 28 day

For concrete strength total in 3 year.

Because 28-day strength of concrete is 90%.

And 3-year strength 98-99%.

Amit said:   8 years ago
It should be after 35 days.

I have a confusion about 100% compressive strength after 1 year and 3 years.

Please tell me surely with proof.

Babu said:   8 years ago
Please tell me correct answer.

Maximum 100% strength to 3 years.
And
IS code 28-day full strength.
The answer is 3 year.

Bharat bhardwaj said:   8 years ago
The Correct answer is 28 days.

Anmol said:   8 years ago
After 28 days, concrete attains 75% of the ultimate strength of 1 year. And it takes 3 years to attain 100% strength.

Normally 28 days is correct.
