It is the early end of strength gain that is of greater interest. Naturally, the concrete gains 95% of its strength in 28 days, 3035% of its strength in 3 days, 6570 % in 7 days and 90% in 14 days. Here, we have given the compressive strength as 4,000 psi at 28 days. Chapter 3, Problem 35P is solved.Solved: Concrete As concrete cures, it gains strength.

Designing and Proportioning Normal Concrete Mixtures

Generally there is a 3- to 4-inch slump concrete at the job site. Add 3 gallons of Super Plasticizer to the mix and you will get 7- to 8-in slump concrete without any water added. One hour later the concrete reverts to the original 3- to 4- inch slump.Concrete Technology Manual Chapter 3, Review of As a consequence, the strength of hardened concrete depends almost entirely on the strength of the cement paste.
