Concrete never gets the full strength in counting the days.

95 - 98 % concrete strength are 28 days. The full strength of concrete 3 years. Because hydration process of concrete 100 % will be 1 years.

Full strength of the concrete could not be specified after any particular period pf time as the strength varies from condition of surrounding and how it will be treated after setting?

Anji said:   10 years ago
