Is 25mpa concrete not good enough?

2018-02-16 · And I polish concrete and can 100% guarantee that a 40 mpa concrete will have a higher earlier strength (e.g. after 14 days) than a 25 mpa slab which means I CAN grind it earlier and achieve outstanding results. Yes stronger concrete equals higher earlier strength all else being equal.

Concrete Mix Ratios - Cement, Sand, Aggregate and Water

Concrete mix ratio is a vital topic in concrete mix design. The four basic ingredients for making concrete are: Portland cement, sand, aggregate (stone) and water. The strength of concrete mixture depends on the ratio in which these four ingredients are mixed.

PROPERTIES AND MIX DESIGNATIONS

to freeze-thaw conditions. Concrete having a total air void content of about 6.5% seems optimal. A mix having 6.5% total air voids will have approximately 1.5% entrapped air voids and 5.0% entrained air voids. Entrapped air is the larger bubbles formed in the mixing process and does not provide much protection against freeze-thaw action.
